How to replace a wheel on an angle grinder. How to change a disc with or without an angle grinder key? Step-by-step algorithm of actions

An angle grinder, or as it is more popularly called, an angle grinder, is an indispensable and very useful tool in our time. Without him, neither here nor there! And if it suddenly malfunctions, then you have to dodge in every possible way, look for alternatives and think about restoring the instrument. At the same time, you cannot use the grinder for its intended purpose because of what appears to be a simple lining when the disc cannot be unscrewed. Or rather, the nut that holds this disk does not unscrew. Here you can “break the woods”, namely, bend or break the key, damage the locking button, break the case, but still not unscrew that same ill-fated nut. So, we will immediately warn you, if it is not too late... If you suddenly cannot unscrew the nut holding the disk with a wrench, then you need to change tactics. And it is precisely this radical method of unscrewing that our article will be devoted to.

Why does he bite the nut on the grinder that holds the disc?

I will tell, perhaps, a well-known truth. It bites the nuts more often on grinders with a significant disc size, say 150-180 mm or more. The thing is that the resulting torque, in the event of a disk impact at the start of cutting, is significantly greater than for a disk of, say, 125 mm. As a result, the nut is tightened so tightly by inertia that it is very difficult to remove it using ordinary and customary methods. Now about special methods.

How to unscrew the nut of an angle grinder (angle grinder) if it is stuck

So, if the key doesn’t work, even if you insert it and hit it lightly with a hammer, then we start using something more serious.

The first thing you can try, but again without fanaticism, is to take a rod, insert it into the holes on the nut and, using a hammer, move the nut in the direction of unscrewing it. The main thing here is not to break the button or tear off the holes, as here

The second thing many people advise is to warm the nut. Warm up the nut. As a result, it is slightly, but physically still obliged to expand. Resizing may or may not help...

There is no need to pull as hard as possible until the lock on the anti-rotation button or the button itself breaks. In this case, it is not the tool you use to unscrew that breaks, but often it is the body of the angle grinder.

The third method is the most effective, and, oddly enough, one of the safest for the grinder herself.
Take and break off the edges of the disk along the nut.

Next, we use a thin metal plate or another disk (thinner), and perhaps a second grinder with a disk. In this case, the broken disk must be turned either with a plate or a disk. We try to sharpen the disk so as not to damage the nuts holding this disk, because they will be useful to us later. We sharpen the entire broken circle in this way until we grind it down and the nut comes off.

This is a matter of 4-5 minutes, no more.

If you use a second disk or metal plate, it is better to insert it into a vice to hold it. Since holding such objects with your hands is dangerous. This method is the most effective!

How to prevent the nut and disc from biting on an angle grinder

And a few words about preventing such unpleasant precedents again. You can use small cardboard spacers, inserting them between the disc and the nut. As a last resort, we use a disk with a smaller diameter, unless, of course, the nut is tightened from above. As a result, you can unscrew such a nut without any problems. It won't pinch, it won't bite on the thread...

And another small video on a topic that I learned from my own experience.

An angle grinder is a universal power tool. With its help, you can cut steel profiles and wood, process concrete and stones, perform grinding and roughing work, and sharpen hacksaws. And for each operation there is a specific circle. For example, you cannot grind surfaces with a thin cutting wheel for an angle grinder - it will quickly break. How to properly place a disc on a grinder when grinding and breaking a wheel or switching to another type of work?

According to the instruction manual, replacing the disc on an angle grinder should be done as follows.

1. Unplug the power tool cord from the outlet.
2. Press the spindle rotation lock button.
3. While holding the grinder's stop button, use an open-end wrench to unscrew the flange nut. You need to turn the angle grinder wrench in the direction of rotation of the disk. If it is difficult to press a button with one hand and operate the key with the other, ask someone close to you to help.
4. Remove the old disc from the spindle shaft.
5. Install new disk.
6. Secure it with a nut manually or using the same universal key. At this moment, you need to hold the stopper with your other hand. Do not overtighten the nut.
7. Plug in the grinder for 30 seconds at maximum speed. If the disk rotates freely, without beating, without touching the protective casing, you can start working.

The delivery set of the angle grinder must include an open-end wrench. Cheap grinders often come with a key Bad quality. It can quickly break (however, this also happens with tools from leading manufacturers). In the end, the key can simply be lost . How to properly install a disc on an angle grinder in this case, without having a suitable tool at hand?

Most reliable way- just buy a new key. You can take a standard one, for a specific flange for an angle grinder, or a sliding one, with the ability to adjust the jaws. But keys for angle grinders are not sold in all hardware stores, and finding the right tool can be difficult. We bring to your attention several tricks with which you can change the disc on an angle grinder without a universal key and save nerves and money.

How to change a disc on an angle grinder without a key?

Method 1. Use a gas wrench. Use an adjustable pipe wrench to grasp the nut and carefully unscrew it without applying much force. Disadvantage: you can crush the nut and break the rotation lock.

Method 2. Make a homemade key for an angle grinder. To do this you will need a long nail (at least 100 mm). You need to cut off the head, the point and give the nail a U-shape. It should be bent in such a way that the “tool” posts fit into the holes in the flange. If the nut is tightened tightly, insert any metal rod between the posts of the nail and, holding it with both hands, rotate the structure in the direction of movement of the circle. At this time, you need to press and hold the spindle lock button. The method is safe, but takes time and additional tools– hacksaws, vices, hammers.

Method 3. Tapping with a chisel. Before changing the disk, you can treat the spindle shaft with WD-40 and wait at least 15 minutes. Then place the tip of a thin chisel at an angle to the hole of the flange nut and gently tap over the entire surface of the hole with a plumber's hammer. Sooner or later, thanks to gentle tapping, the nut will move, and it will be possible to unscrew it manually. The disadvantage of this method is that the holes can be damaged and the flange can be damaged.

Method 4. Heat the nut. If it is difficult to unscrew the angle grinder nut by hand, you can heat it a little with a gas burner or autogen. You need to wear gloves when unscrewing the flange to avoid getting burned. This is the riskiest of the proposed methods. It is possible to overheat the bearings and oil in the gearbox of an angle grinder.

Finally, I would like to mention Several important points regarding replacing a disc on an angle grinder.

The main thing is that when changing a disc on an angle grinder, do not violate safety precautions and perform all manipulations with the tool unplugged.

An angle grinder (popularly called “grinder”) is the most common tool for home craftsmen after an electric drill.

Despite the ease of use, “hobbyists” often have questions about servicing the tool, especially when emergency situations arise. As a rule, breakdowns occur due to improper use of the tool.

Main uses of angle grinders

It is with such attachments that emergency situations most often occur.

Let’s take a closer look at cutting wheels

The question of which side to place the disc on the grinder does not have a correct answer. Abrasive wheels do not have a programmed direction of rotation, so it doesn't matter how you set it. The direction of rotation (from yourself or towards you) is determined by the position of the protective casing. The choice depends on the position of the tool that is convenient for the operator.


In addition, the direction of the flow of sparks (or stone dust) depends on the position of the casing.

note

It is advisable to place the disc with the front side (with the marking) facing up. In this case, you will not forget which nozzle is installed: for stone or metal. They are not interchangeable.

To install the disk on the shaft, the kit includes a dismountable flange. The lower part is rigidly fixed with chamfers, top part– a regular self-tightening nut. It is she who determines in which direction the disc on the grinder should rotate. During operation, the threaded connection is tightened, preventing the nozzle from coming off.


Sometimes the kit includes spacer washers designed to dampen transverse vibrations. You can make them yourself from thick electrical cardboard or paronite.


To secure the flange, a special open-end wrench is included with the tool. The shaft is fixed with a clamping button to create the necessary tightening force.

The main spare part of an angle grinder (angle grinder) is a replaceable cutting tool. An abrasive disc rotating at high speed cuts, grinds or polishes materials. For metal processing, circles are made from abrasive chips; for wood, steel cutters are used; for stone, metal discs coated with diamond are used. Special attachments - brushes, flap sanding wheels - further expand the capabilities of your grinder. Next, we will find out what types of discs there are, how to properly remove the old one and install a new one, and also consider possible problems problems that arise during the replacement process, and ways to solve them.

Types of discs for grinders: how to choose the right one

The industry produces grinders and wheels for them in standard sizes: 115, 125, 150, 180 and 230 mm. Angle grinders from 180 mm are used for cutting stone. The most common size of machines for home and garden use is 125 mm; they produce the most discs and attachments for them.

Attention! Always select a disc that matches the size of your angle grinder. A disc with a smaller diameter can be installed in an angle grinder. But removing the casing and installing a disk with a larger diameter is extremely dangerous!

We suggest dividing the discs according to their purpose: cutting, grinding, sharpening and roughing. Let's look at each type in detail.

Cut-off

Cutting through metal

Inexpensive steel disc from Luga plant

Cutting materials is the most common task during repairs and construction; a simple abrasive wheel for metal will easily cut through a steel bar, roofing iron or plastic. These wheels are made of corundum (crystalline alumina) or electrocorundum (synthetic corundum).

Sawing stone

The budget stone disc is produced by the Luga plant

To cut stone, we recommend taking a special disc - they use a different abrasive - silicon carbide. It can handle white sand-lime brick and slate. But red brick, tiles and especially concrete will not succumb to it - you need to take a diamond blade.

Letting go of the tree

These are also available for grinders

The blades that cut wood are very similar to the blade of a circular saw. Actually, this is a disk for a circular saw, only the mounting diameter of 22.2 mm is suitable for the grinder spindle.

Diamond

As you know, diamond is a very hard mineral, so diamond discs can easily cope with red brick, porcelain stoneware, and tiles. The main material that is cut with diamond blades is concrete.

Diamonds must be handled with care - the disc cannot be used to cut steel, and it must not be overheated. After just two minutes of sawing concrete, the disc will become very hot - take a break. Slots are made around the circumference of the dry cutting disc for cooling.

They produce discs for wet cutting of ceramic tiles and porcelain stoneware. The water cools the disc and washes away dangerous dust.

How to choose the thickness of cutting discs

Every master knows that the thinner the tool, the better. Less material goes into chips, it’s easier to saw, and the cut comes out cleaner.

Discs for grinders 115 and 125 mm are produced with a thickness of 1.0–2.5 mm. Discs 150 and 200 mm - thickness 1.8–4.0 mm. Pressed corundum powder is reinforced with synthetic mesh.

Attention! The thinnest disk (1.0 mm) “walks” when sawing and breaks easily, its pieces fly at high speed in all directions. Don't forget to protect your eyes and hands.

Grinding

The next most important job that craftsmen entrust to an angle grinder is grinding and polishing. Similar processing is applied to metal, wood, plastic and other materials.

Flap wheel for wood: dozens of sanding flaps quickly cut off chips

The choice of grinding discs is very wide. If you are restoring a sideboard, a flap wheel is suitable for removing layers of shellac. It covers large surfaces and cuts a lot of material in one pass.

The sanding attachment is a plastic circle to which sandpaper is attached with Velcro

Another attachment is screwed onto the grinder spindle. Sandpaper is attached to it with Velcro. For coarse processing - P60 or P80, for finer processing - P120 or P180. As the grain size decreases, grinding smoothly turns into polishing.

Polishing disc made from alpaca wool

Especially for polishing, there are attachments in the form of pads, felt or fabric discs. Before work, polishing paste, for example, GOI, is applied to them.

Grinding wheels

In fact, there are special machines for sharpening tools - sharpeners. Nevertheless, the rotating disk of the grinder is capable of correcting a dull ax or cleaver, knife or scythe. Taking into account the wishes of the craftsmen, the industry produces 115 and 125 mm sharpening discs for grinders.

Sharpening discs turn the grinder into a sharpener

The discs are made of coarse abrasive, compressed into a thick plate (more than 5 mm) with a bulge in the center. If you install such a disk on a spindle, the flange is hidden in the recess and does not protrude above the plane of the disk. Coarse grinding wheels are also used for cleaning welds.

Sanding brushes and discs

Craftsmen renovating mid-century homes are faced with removing oil paint from walls. Wire brushes are suitable for this type of work.

Not a single paint can resist such a steel cup.

The brush is a cup with steel or brass strands around its circumference. They differ in the thickness and rigidity of the wire - for coarse and fine stripping. The brush is screwed onto the spindle using an M14 thread.

Stone grinding disc cuts old cement evenly

After removing the oil paint, the curved concrete wall must be sanded. Only a grinder can cope with such a task. Working surface diamond grinding disc - perpendicular to the axis of rotation. Synthetic diamonds cut and smooth concrete like sandpapering wood.

How to make a replacement

It’s already inconvenient to cut with such a disk

Grinder discs are a consumable material; when cutting, they wear out quite quickly. A worn out disk must be replaced. Let's see how to do this using our Interskol-115 angle grinder as an example.

Attention! Before starting work, check that the machine is disconnected from electrical network!

Step-by-step instruction

The disc is mounted on the spindle of the angle grinder with a clamping flange with an M14 thread. To unscrew the flange, the grinder kit includes an open-end wrench. Its pins cling to the flange holes.

An open-end wrench will unscrew the flange

To unscrew the flange, the spindle must be locked. To do this, a clamp is made on the side of the case opposite to the disk. When you press the button, the cotter pin enters the hole in the driven disk of the gearbox and prevents the spindle from rotating.

The button locks the spindle

Insert the open-end wrench into the flange holes. With our right hand we press the lock button, at the same time with our left hand we turn the key counterclockwise and remove the flange from its place.

An open-end wrench is inserted into the flange holes

Our grinder rotates clockwise. If your direction is different, remember - you need to unscrew in the direction of rotation of the disk.

If the flange gives way, unscrew it by hand, remove it and put it aside.

Top flange removed

We remove the old disk. We don't need it anymore, we can throw it away.

Old disk removed

Remove the bottom flange.

Bottom flange removed

During intensive sawing, a hardening of burnt metal and abrasive particles is formed on the inside of the casing. Let's use a steel brush to clean the casing.

The brush cleans the casing

We install the lower flange on the spindle, making sure that the flats on the flange coincide with the grooves on the spindle. Place a gasket on top.

Bottom flange and gasket installed

If your grinder does not come with gaskets, such a washer can be cut out of cardboard or tin.

We put the disk in place and cover it with the second gasket.

New disk installed

Thanks to the gaskets, if the disc gets stuck in the material and breaks, you can still easily unscrew the flange.

We tighten the upper flange by hand against the direction of rotation of the wheel (in our case, clockwise), holding the abrasive disc. With your right hand, press the lock button and twist it by hand until you feel resistance. Insert the open-end wrench and tighten it a little more, no more than a quarter turn. There is no need to tighten the flange too much; the disc will warp.

The disk has been replaced, the angle grinder is ready for work

At this point, the replacement of the disk is completed, you can continue sawing. Sometimes when changing a disk, obstacles stand in the way of the master. We will consider what to do in such situations further.

Possible difficulties in the process

What to do if there is no key

The open-end wrench is not attached to the grinder and may well get lost. How to unscrew the flange in this case?

1. We make an open-end wrench from a nail. We take a weaving nail and bend it in the shape of the letter “P” so that the distance between the vertical posts is equal to the distance between the holes in the flange. Cut off the tip and head with a hacksaw. We stick the resulting “key” into the holes of the flange and unscrew the mount, not forgetting to fix the spindle. If the nut is tightly tightened and your fingers are not strong enough, insert another nail between the vertical sections - the lever will be greater.
2. We use the gas key. We take a large pipe wrench, it is also called a “gas wrench”. Plumbers use this tool to twist steel pipes. We spread the key so that it covers the entire flange. We try to move the nut from its place, securing the spindle. The gas key has a huge leverage. If you apply force, the spindle lock will break.
3. Tapping the nut. Take a metal rod or thin chisel. Lock the spindle. Tap the edge of the hole in the flange in the direction of rotation of the disc. This way you can move the nut out of place. This method is not the safest: the tool damages the flange and breaks the key holes.

The disk is broken, the flange is jammed

Let’s imagine that a craftsman is making an anvil from a steel rail and cutting out the tip with a grinder. The disk became distorted in the material and jammed. The motor continues to run and tightens the flange tightly. All work stopped. How to change the disk if now it does not unscrew?

1. Let's disassemble the gearbox. Unscrew the fastening and remove the gearbox housing. We hold the spindle shaft with a gas wrench or pliers, and twist the flange with a horn or another gas wrench. The disc is not affected by this method; the normal one can also be removed. good disc. The method works even if the spindle lock is broken.
2. We use two gas keys. The method does not require disassembling the grinder. Carefully break out the remains of the disk to get to the bottom flange. We clamp the upper flange with the first gas wrench, and engage the lower flange with the second key. We twist in opposite directions.
3. Heat the nut with a torch. We heat the stuck nut with a portable gas burner. The nut will expand as it heats up and can be easily unscrewed.
4. Cut the flange with a hacksaw. Some craftsmen prefer to cut through a stuck flange with a hacksaw. The method is barbaric - you will have to buy a new nut.
5. Lubricate the threads with penetrating lubricant. Spray the stuck nut with WD-40. It penetrates into narrow crevices and threaded connections. After a five-minute break, try to move the nut with a wrench.
6. Cut out the remaining disk with a hacksaw. We break the disk with pliers while it is possible. We remove the protective casing, insert a hacksaw into the gap and cut out the remains of the abrasive wheel. Delicate and reliable method. Does not require disassembling the grinder and harsh influences on the tool. The master must have patience, as the method will take up to an hour. The abrasive quickly wears out hacksaw blades; you will need several of them. The advantage is that the angle grinder maintains the warranty, there is no risk of breakdown. These circles ensure that the flange does not get stuck

   Such discs can come complete with an angle grinder, or you can cut them yourself.

   For spindles of angle grinders, factories produce thin and thick abrasive discs, metal cutting wheels, and nylon brushes. All these spare parts turn the angle grinder into a universal tool and reveal its capabilities in unexpected ways. For example, a grinder turns into a sharpener. Changing the disk is not difficult, but the technician must know about some features of the process so as not to get into a difficult situation.

When working with any mechanisms, you should always expect emergency situations, which cannot always be resolved in accordance with the recommendations of the manufacturers. The angle grinder is no exception. During operation, you may encounter excessive clamping of the cutting disc. This problem occurs especially often with large, powerful models, with a power of more than 2 kW. What should you do if the disc on the grinder is stuck or the nut cannot be unscrewed? We will deal with this issue further.

What is causing the problem?

When rotating at idle, it is difficult to encounter a similar problem. Especially when working with light wheels and tools with a soft start function. However, after increasing speed and contact with the surface being cut, the following occurs:

1. When material resistance occurs at the wheel, the angular velocity of rotation sharply decreases and it slows down.
2. The engine, by inertia, continues to operate for several moments at the same speed, dragging the gearbox and spindle with it.
3. The locking nut is tightened by inertia more strongly along the threads of the spindle head, thereby pressing in the cutting disc.

That's it, the process of tightening the fixing flange is completed - an emergency situation is obvious. The following factors influence its occurrence:

• Large circle size.
• High power of the tool.
• Massiveness of the rotor.
• A sharp increase in cutting depth, i.e. increase in resistance.

In this case, removing the disc from the grinder can be very difficult. Additional measures need to be taken.

Replacing a disk in normal mode

When working regularly with an angle grinder, you need to constantly change the circles, which are consumables. If the tool is no longer comfortable to work with, then the worn abrasive wheel should be replaced.

Important! Be sure to check the electrical disconnection to avoid personal injury.

Step-by-step algorithm of actions

The circle is secured to the spindle head with a locking nut having an M14 thread. The standard configuration includes an open-end wrench with special protrusions for engaging with the holes of the fixing flange.

To unscrew the nut, you need to fix the spindle. For these purposes, there is a special lock located on the back of the angle grinder. By pressing the button, you will secure the gearbox with a cotter pin, eliminating the possibility of its rotation.

Insert the key into the holes. Hold the latch with one hand, and with the other turn the wrench counterclockwise, moving the nut.

The direction of movement of the disk is usually clockwise. However, there are models that may have something different. In any case, unscrewing occurs in the opposite direction to rotation.

Once the nut is in place, it can be unscrewed by hand without any effort.

Remove the retainer and the old circle.

Remove the bottom flange.

After intensive work with a tool with metal inside the casing, you can find a layer of burnt scale with abrasive. Use a steel brush to remove residue.

After cleaning, install the lower flange in place, aligning the grooves of the spindle with the grooves of the flange. A gasket is placed on top.

If your model does not have additional spacers, then such washers can be prepared from plastic or thick cardboard. Next, you need to correctly place the disc on the grinder and cover it with a similar gasket.

Important! Installed spacers allow you to easily unscrew the nut, even if the disc is pinched or broken.

Use your hand to tighten the top clamp counterclockwise (counter-rotation), supporting the cutting wheel. In this case, you also need to tighten the spindle lock and tighten the flange until there is noticeable resistance. Use the open-end wrench to tighten it with a little more effort. Do not over-tighten the fastener, otherwise you can overtighten the circle and it will warp.

The nut is stuck - how to unscrew it?

Removing a disc on an angle grinder if it is bitten is not so easy, especially without damaging the cutting element or tool. We will also consider several options for action.

Replacing a counter-rotating disc

This method has several advantages - it can be done without a key and with a broken spindle lock. Beginners in working with angle grinders mistakenly believe that if the stopper breaks, it is almost impossible to unscrew the nut. However, this is not the case. You don't even need keys.

The point is that the abrasive wheel needs to be rotated in different directions. Wearing thick gloves, you need to hit the cutting edge of the circle several times. This is what will ensure variable movement in different directions. As a rule, a couple of sharp blows are enough so that the nut can be easily unscrewed.

Open-end wrench and socket head

In this case, you will have to slightly modify the existing standard tools - a 17 mm open-end wrench and a 24 mm socket. The thickness of the key is ground down to 4 mm. 4 protrusions are machined on the head and fit into the holes of the retaining nut.

After preparation, the key is placed in the space under the disk, and the head is put on the flange of the angle grinder and rotated in the direction opposite to the rotation of the wheel. After this, you can easily remove it and install a new one.

Heat

This is one way to remove a disc from an angle grinder without a key. The fixing nut is heated with an industrial hair dryer or a gas burner. After this, the flange will unscrew much easier. However, there is a risk of damage to the plastic parts of the angle grinder or gearbox.

With a nail

For these purposes, a 100 mm nail is best suited. It should be bent into a U-shape so that the ends fit freely into the holes of the clamping flange. The tip and cap are removed. By inserting a nail into the holes, the latch is unscrewed. If the manual effort is not enough, then add a nail or screwdriver in the shape of a lever.

Using a gas wrench

The use of this tool is justified by an increase in the applied moment of force due to the increased arm. Using a gas wrench will make it much easier to unscrew a jammed connection. However, when eliminating snagging, it is important to remember that if you apply excessive force, there is a risk of damaging the spindle lock or clamping nut.

Using a rotary hammer or drill in chiselling mode

You can unscrew the disc on an angle grinder without a key using a drill or hammer drill, having first switched it to jackhammer mode. A suitable drill, most often 6 millimeters, is used as a working attachment. Place the drill against the edge of the hole in the clamping nut, fix the movement of the spindle and briefly turn it on to move it from place. This method allows you to turn away even very complex snacks.

Tapping the nut

This method is similar to the previous one, only you can use a suitable metal rod or chisel. Having fixed the spindle head, tap along the edges of the clamp holes in the direction of movement of the wheel. By slightly moving the lock from its dead point, you can unscrew it by hand. However, the method is not the most harmless for the tool - the mounting holes for a standard key are damaged.

Cutting wheel destruction

You can unscrew a jammed nut by completely destroying the disk. If there is already damage, you can break it off with your hands, but most often this will not be possible. It’s better to take a hacksaw or metal blade and cut it. This will leave you with a center ring and hard-to-reach pieces. Having found a suitable plate, holding it in a vice, grind off the remaining abrasive on it to a metal ring. After this, it will be easily unscrewed with a standard key.

The most radical way to unscrew a jammed clamp nut is to cut it. It is advisable to resort to it only in extreme cases. Of course, you can find a new one, but you will have to spend your time and money. It is not uncommon for spare clamping elements to be included in the delivery set of an angle grinder.

Measures to prevent jamming

By taking care of the safe operation of the angle grinder in advance, you will save yourself from the need to take measures to eliminate an emergency situation. Such events include:

• Place cardboard or plastic washers between the disk, flange and spindle head. They do not allow the tool to jam, but even in the event of a corkscrew, they can be removed/melted and the element can be easily unscrewed.
• The abrasive wheel must be installed correctly. To do this, place the front side of the circle on the support flange (with the picture facing the gearbox). It should not come into contact with the clamping nut. In this case, the standard metal ring in the center will act as a washer preventing jamming.
• Weld a regular nut onto the clamping flange, which allows you to press installed disk using a regular wrench.
• Check the tightening force. No excessive effort is required to install the cutting element. Otherwise, it will jam under intense loads.

Safety regulations

When working with an angle grinder, it is important to remember that this tool has an increased risk of injury. Accordingly, you should not lose vigilance under any circumstances, even when disconnected from the power supply. When using auxiliary tools and materials to replace the disk, pay close attention to them. Plumber tools can also cause significant injury.
