Disc For Angle Grinder For Removing Paint

Metal nozzle for cleaning, removing rust and paint

Such a nozzle is a metal brush. With its help, you can remove paint or rust, level some surface. But for polishing, grinding such attachments are unsuitable, since after them scratches remain on the material.

Cutting attachments

For cutting metal, those circles are used that are intended specifically for him. At the same time, when working with other materials, they heat up to such an extent that sometimes they fly apart and can seriously injure. There are labels on the cutting discs themselves, which indicate the permissible rotation speed. The material with which this disc should be used is also indicated. It is also necessary to understand that the diameter of the circle depends on the thickness of the workpiece.

Disc For Angle Grinder For Removing Paint

Angle Grinder Accessory Types: For Cutting, Grinding, Rust Paint Removal

Angle grinder is called angle grinder in detail about its choice I wrote not so long ago. It is a versatile tool with which you can perform various works. They cut it, saw it, grind it, clean it from rust, remove the old paint. This has to be done both during construction and during repairs, and just in everyday life. However, various operations require a suitable attachment for an angle grinder.

Many users do different jobs with the same attachment. This leads to both a shorter tool life and increased wear on the working disc. The fact is that manufacturers produce circles that differ not only in size or thickness. They have differences both in the material from which the work surface is made, and in the form.

It should also be borne in mind that each processed material has its own hardness. Therefore, the safety of the person working with the tool depends on the correct selection of the right circle.

Grinding, polishing

For grinding and polishing metal, glass, porcelain and some other materials, we use Velcro attachments (with adhesive felt) made of coarse wool. For grinding, there are discs with sandpaper. When choosing a disc, you should pay attention to its diameter. Too small disk will take a long time to process.

There are carbide coated discs available. They come in different sizes and shapes. You need to know that they cannot be used for working with metals.

It should be borne in mind that professionals work as they are used to. But for the amateur, both the size of the disc and its shape matter. Therefore, consultation with the seller will not hurt, especially since manufacturers produce a wide range of attachments for various types of work.

Sewing off a jammed circle

If, after applying the first 3 methods, the nut does not unscrew, then the remaining abrasive disc between the flanges can be ground off. To do this, do the following.

  1. Use pliers to remove the rest of the circle around the edges of the nut as much as possible.
  2. Clamp a piece of sheet metal as thick as the disc itself in a vice, turn on the angle grinder and grind off the rest of the wheel on the end of the sheet metal.

But the use of a stationary abrasive wheel requires great care, because when grinding off the remains of the tool, the geometry of the flange can be damaged. If this happens, you will have to face the nut.

Using a puncher

Some owners of grinders, in a situation where the clamping nut is jammed, install a nozzle in the perforator “chisel” or “jackhammer”, insert it into the hole of the flange at an angle and turn on the jackhammer mode without rotation. Accordingly, the stop button must be pressed. Just a couple of gentle clicks with a perforator are enough (so as not to break the shaft retainer), and the nut will begin to turn.

Heating nut

The nut can be heated with a gas torch, hot air gun or blowtorch. The heated flange can usually be unscrewed with a standard wrench for an angle grinder.

Cutting discs

The most common task performed with an angle grinder is cutting various materials. The choice of tool material depends on what material needs to be cut.

  1. Metal cutting. The metal cutting disc is made from crystalline alumina corundum, as well as from a synthetic corundum called fused alumina. The main color of wheels for cutting metals is blue.
  2. Cutting stone and concrete. For stone cutting, choose a disc made of a different silicon carbide abrasive material. This abrasive cuts white brick (silicate) and slate with ease. But to cut red brick, some types of concrete or ceramic tiles, this circle material will not work. Stone discs are available in green.
  3. Cutting ceramic tiles, red brick, porcelain stoneware and concrete. For these purposes, a diamond disc is already used. This nozzle is made of metal, an abrasive mass with diamond chips is applied to the cutting edge. The picture above shows a segmented saw blade designed for dry cutting of material. All-metal discs require water cooling during operation.
  • Wood cutting. Although there are saw blades on the market for wood that are no different from circular saw blades, it is best to avoid using them for safety reasons. When working with such a tool, the user often receives severe injuries due to jamming, bouncing, accidental slipping of the tool, etc.

Therefore, if you are still going to use a saw blade for wood, then you should adhere to safety measures. The angle grinder must be fitted with a protective cover and handle and the user must wear a face shield or goggles. In addition, you must not use this tool to cut materials that are not intended for it.

Roughing

If it is necessary to remove a layer of paint or other application, as well as rust from any surface, use a brush. They are disc or bowl-shaped with built-in metal wire.

The wire in these attachments can be twisted or loose. Its thickness can also be different. The thicker the wire, the coarser the roughing is used for the roughing disc or bowl and vice versa.

Using a penetrating lubricant

Liberally spray the flange to shaft connection with WD-40. It tends to penetrate into inter-threaded spaces and small cracks. After applying the liquid, wait about 5 minutes and try to unscrew the fasteners with a standard wrench.

From the walls

First of all, in order to remove paint from the wall, craftsmen try to use brushes with thick twisted wire (discussed above). This method is quite effective, but a lot of dust is generated during roughing work. Therefore, it is necessary to use protective equipment (goggles, respirator). It is also recommended to use a vacuum cleaner with a special attachment that completely hides the brush.

Bowl nozzles are also used to remove paint from concrete walls. The angle grinder must be held at such an angle that the paint layer is removed, but the tool does not deepen into the wall.

In addition to roughing work, this nozzle is also used for leveling surfaces, removing various sagging on the wall, for removing plaster, putty, etc.

Wood cutters are available in a large assortment. They differ in size, position and shape of the teeth. Polishing and Grinding

There are many types of such circles. They can be cloth, spongy, felt and with replaceable abrasive.

To work with them, it is necessary to use special pastes with fine abrasives, as well as various liquids. Fine abrasive wheels are used for cleaning and rough grinding. The use of discs for grinding makes it possible to bring the surface of any material to the desired roughness. Such angle grinder attachments are used for polishing car body.

Using a drill or punch to remove paint from walls.

If you have a powerful drill, you can try the paint removers designed for the drill.

Drill bit

Drill attachment for attaching sheets of abrasive material. Fixation is due to the Velcro. To be honest, this is complete nonsense and in fact such a nozzle turns out to be useless. Never buy one.

You can try this brush. The removal process turns out to be quite effective and of high quality. The surface cleans well, but don’t think that you can clean even a quarter of a square meter in an hour with such a brush. Suitable for those who have a lot of time.

Hammer drill owners are more fortunate than their neighbors. Thanks to a specially designed spatula nozzle, you can quite successfully beat off a layer of old paint along with a layer of putty and plaster and concrete :). A square meter per hour is quite realistic. I think the neighbors hated me because I pounded for 2 hours on Saturday.

The attachments were immediately purchased after purchasing the hammer drill. Such pribluds are inexpensive, 100-200 rubles for each.

Nozzle for removing paint and top coat of putty and plaster

I tortured the neighbors with this attachment and tested their patience, but no one seemed to come running to complain. Everyone reacted with understanding.

I note that the wall after using the punch becomes very impartial, but it completely removes the paint, and then you can re-plaster and putty.

On the wall, grooves were previously made for sockets and switches. As a result, the wall generally turned into a terrible concrete mess. In one of the next posts I will show you how I plastered it.

Purpose:

  • Surface cleaning before painting.
  • End and edge processing.
  • Scraping parquet floors.
  • Sanding wood surfaces.

Sharpening discs

This category of discs is designed for rough metal work. The sharpening disc can be used for cleaning welded seams, chamfering cut metal parts, and for sharpening tools (drills, chisels, etc.) if there is no grinding machine nearby.

It is worth knowing that when installing such a disc, the revolutions on an angle grinder must be set to the minimum or not exceeding the values ​​indicated on the abrasive wheel.

The grinding wheel can be distinguished from the cut-off wheel by its thickness (at least 5 mm) and by the presence of a recess in the center for more convenient use of the plane of the disc for sharpening the tool.

With the proper use of an angle grinder, this device becomes a versatile tool that can handle any material. In this case, the main factor is to choose the right attachments for the angle grinder.

Using an angle grinder, you can perform many different operations using different discs and attachments: peeling, sharpening, polishing, and also perform other types of work where you can use the rotational movement of the tool.

Overview of grinding and grinding wheels for an angle grinder

Removing paint from walls or metal surfaces, as well as removing rust, takes a lot of effort and time. Therefore, it is sometimes impossible to do without the use of a power tool. An angle grinder (angle grinder) with special grinding attachments can be used as a device to facilitate the process.

Paint Remover Tips

Old paint most often has to be removed from either walls or metal surfaces. In each case, different types of angle grinder attachments are used.

From metal surfaces

For roughing work on metal, whether it is removing a layer of old paint or removing rust, craftsmen use brushes. They look like a brush made of twisted or non-twisted metal wire inserted into a metal cup, or a disc of the same wire.

Depending on the quality of the roughing work you want to carry out, the thickness and hardness of the brushes are selected. It should be borne in mind that the metal wire used in brushes leaves scratches on the treated surface. Therefore, it is better not to use them to remove paint, for example, from a car body. They can only be useful for removing rust and paintwork from hard-to-reach places.

For metal-friendly roughing, it is better to use special discs made of silicone carbide fibers (XCS), they are usually black. Also, for these purposes, Clean and Strip discs, which are more resistant to wear, are used. They are blue in color, have a similar structure, but are composed of nylon threads.

This grinding wheel is available in 2 versions: for a drill and for an angle grinder. Its distinctive feature from other types of nozzles for removing paint from metal is that it does not clog and does not damage the metal in the form of scratches. They also successfully remove welding spatter, rust, various sealants and anti-corrosion coatings.

Often, flap attachments for an angle grinder are used to remove paint from metal. They represent a disc with sandpaper glued to its plane in the form of petals.

For rough surface treatment, nozzles with a large grain size are used. For finishing work, it is necessary to select a grinding wheel with fine sandpaper. Although this sanding disc will wear out quickly and become clogged with remnants of stripped paint, it can be easily repaired. How this is done can be understood from this.

From the walls

First of all, in order to remove paint from the wall, craftsmen try to use brushes with thick twisted wire (discussed above). This method is quite effective, but a lot of dust is generated during roughing work. Therefore, it is necessary to use protective equipment (goggles, respirator). It is also recommended to use a vacuum cleaner with a special attachment that completely hides the brush.

Bowl nozzles are also used to remove paint from concrete walls. The angle grinder must be held at such an angle that the paint layer is removed, but the tool does not deepen into the wall.

In addition to roughing work, this nozzle is also used for leveling surfaces, removing various sagging on the wall, for removing plaster, putty, etc.
