Sanding attachment for drill: types, purpose

The drill is an indispensable tool for repair and construction. A variety of nozzles helps to carry out a large number of works. This is the drilling of technical holes, and the assembly of furniture, and kneading mortars. The versatility of the electric drill allows you to save on buying a fairly wide range of various additional tools.

One of the most interesting applications is grinding with a drill. And the nozzles present on the market will allow to work with concrete, wood, metal, plastered surfaces. You should consider this topic in detail.

Electric drill. Kinds

If you recall the old tool, then the cartridge in it changed only with the help of a key. Modern models are already equipped with quick-release heads.

There are several basic options for this tool:

• Drums. The process of mechanical impact. Designed to work with materials that have good strength properties.
• Impudent. Used for drilling holes in less strong bases.
• Corner ones. Are applied in the limited space.
• Mixers. Equipped with additional handles, which gives additional convenience when kneading mortars.
• For diamond drilling.

When choosing a drill, you should pay attention to the main characteristics:

• Power. For household purposes, the figure is 1500 watts.
• The speed of rotation (up to 3000 W is characteristic of electric relays for domestic use).
• Drilling diameter. For home use, no large parameters are required.

The larger the range for each value, the more universal the tool becomes. Everyone chooses a drill, based on their needs. Someone needs a professional, someone - a household universal. But one is indisputable: when there is a possibility to shift the mechanical process to the "shoulders" of the power tool, no one will refuse to do this. Yes, while still saving a considerable amount on the purchase of additional equipment.

Types of grinding work

The versatility of the drill and the variety of attachments allow it to be used for:

• Polishing metal, wood products, glass, paint and varnish coatings;
• Stripping metal from corrosion, old paint (preparation of the substrate);
• Grinding of metal, wooden products, the edge of glass;
• Stripping scales, burrs, rushes on metal, wood, concrete.

This is just a small list of works for which you can use an electric drill and specialized components. In fact, when there are any difficulties, this tool is just necessary.

Classification of grinding nozzles

There are a number of modifications of such devices: plate, cup, end, drum, disc, soft, abrasive, fan.

The grinding nozzle on the drill looks similar to the replaceable blocks for specialized machines with the only difference being that instead of a threaded joint a pin is arranged for fixing the electric drill in the cartridge. Depending on the size of the tool, power, speed of rotation, work of the worker is the quality of grinding or polishing. Some craftsmen come up with additional tools for fixing the drill in working order, which greatly facilitates the processing of parts.

Each of the above grinding nozzle on the drill has in its modification a number of options for execution. All kinds and spheres of their application should be considered.

Cymbals

Such a nozzle for grinding can be made in two versions - plastic and rubber. The second variant of the base is considered more popular. With its help, the parts are treated more sparing. Consequently, damage due to excessive pressure will be minimized.

The polishing base of these nozzles is covered by grinding paper, which is fastened by its adhesive layer.

The main difficulty of the work is the inability to hold the tool strictly perpendicular to the surface, which leads to defects on the machined plane.

For such cases, the manufacturers provide a grinding nozzle for a drill with an adjustable angle of the fixing pin. True, the cost of such a device is quite high. When choosing a nozzle, you should pay attention to the presence of a soft interlayer between the emery layer and the substrate. This helps to avoid large defects in grinding.

The size of the granularity and rigidity of the sandpaper will determine the scope of application of this device. This can be roughing and finishing the wooden, metal surface. Another interesting use is the sanding of the walls after plastering or shpatlevaniya. The process is quite dusty, and the use of PPE of respiratory organs and eyesight is absolutely essential.

Cup

The devices are made in the form of a bowl. It can be brushes with a metal bristle, and soft filling, for example, foam rubber. Everything depends on the planned work.

Metal brushes are used to clean the products from the old paint layer, rust and for wood burning. For example, for the process of selecting a texture. The brush rinses the wood fibers, after which the plane is neatly grinded already with the plate nozzle. And then apply stain and lacquer. Such items after finishing have a clear wood pattern, texture. Soft fillings of cup devices are used for fine polishing and stripping.

Disk

It can be said that this is a kind of cup attachment, with the only difference being that the bristles are directed from the center to the edges. That is, the process will be done in an end-to-end manner.

To disk it is possible to carry also a kind of fan. This is when the petals are attached parallel to the base. These devices are used for cleaning hard-to-reach places of products from old finish, corrosion. To work with such attachments requires a certain skill.

Drum

The devices are available in the form of cylinders. The working area is located on the side surface on which the grinding paper is put. It can be infinite and with an end element. Fastening is made by inflating (rubber and pneumatic blocks) or fixing bolt.

Such a grinding nozzle for a drill is used for processing metal, wood, glass. The most actual application is the scouring of radius holes and end elements.

Fan (petal)

They are a grinding wheel, on which a lot of petals of sandpaper or other abrasive material are glued in a circle . Such devices are used more often for processing of wooden surfaces. There is another option, when the petals are fixed in the form of a cylinder. Due to their mobility, the wood grinding head is used for geometrically complex parts.

Soft

These nozzles are used for soft polishing products. Produced from foam rubber, felt or twisted rope material, leather. Mounted with two washers. Such products are designed for soft polishing of paintwork surfaces, as well as cleaning debris from vulnerable to abrasion planes.

End grinding wheel

It is available in the form of a cylinder, ball, cone. It is made of a grinding stone or a soft material. Such elements are used for hard-to-reach places, small parts, even for the processing of precious metals. Abrasive nozzle on the drill can be used for finishing metal, glass surfaces. In fact, the file is replaced, only the speed of puffing is many times greater. Soft serves for polishing.

Abrasive stone

This replaceable block grind and remove errors not only from metal, but also from concrete bases. For example, cleaning strikes when working with bulk floors. The size of the abrasive fractions is responsible for the quality of grinding and polishing.

Types of grinding bases

Depending on the material, a grinding wheel is selected. There are several main types:

• Sandpaper. Such material has a wide range of stiffness and granularity. The larger the abrasive, the rougher the surface will be. Closed and open paper also exists. The first option is used for metal processing, and the second one for wood. In the open version, the distance between the crumb is larger, this allows not to accumulate on the plane of the wood shavings, sawdust.
• Soft materials. As already mentioned, it can be foam rubber, felt, twisted rope surface, skin. Nozzles with this material allow you to perform fine polishing.
• Grinding stone. Another type of abrasive coating, which allows you to remove more complex defects from the plane. Such a device can handle metal, concrete.

Variants of materials for attachments and a variety of devices allow the use of a drill for grinding and polishing various materials, up to the use in jewelry.

Features of work

As it was mentioned before, the electric drill is a multifunctional tool that can replace a number of other devices. And if on sale there is no that the necessary nozzle for a drill, it is possible to take similar for болгарки and to fix, using an adapter.
It is made in the form of a rod with a thread.

The main difficulty in grinding an electric drill is to hold the appliance correctly with respect to the polished surface. If the work is done using a grinding wheel 150 mm, while not observing a clear horizontal direction, radial marks may appear on the plane. In any case, you should first practice on the rough surface.

There are two methods of grinding an electric drill:

• Hold the tool on the weight. Disadvantages of this method have already been announced. The advantage is the ability to grind hard-to-reach places and products with complex geometry.
• Using a fixed drill on the carpenter's desk. This method is good because now the quality of the grinding is increased due to the fixation of the tool, and in some cases - the part itself. The drawbacks can be attributed just to the lack of mobility of the electric drill. It will be required to remove it from the fasteners for cleaning hard-to-reach places.

When working with the start button, the speed of rotation is regulated, which means the intensity of grinding or polishing the surfaces. It is recommended to ensure that the instrument does not overheat. Allow time for cooling.

When grinding and polishing, personal protective equipment should be used: glasses, respirator, gloves. All these PPEs will be able to protect the respiratory, hearing, and visual organs from dust, which will be formed during the sanding process. This must be done especially when processing glass, stone, metal, wood. Do not ignore the use of personal protective equipment.

Conclusion

A drill is really a universal tool. Its use for grinding surfaces is completely justified in everyday cases. This is a good alternative to manual sanding of surfaces. If intensive use is required over a long period, it is better to buy a separate grinding machine, the range of which is quite wide.

So, we found out what kind of grinding attachments there are for a drill. The choice of a particular type of product depends on the specific objectives of the work.
