Drill is an indispensable tool in the repair and construction. A variety of nozzles helps to carry out a large number of works. This and drilling technical holes, and the assembly of furniture, and the mixing of mortars. The versatility of the electric drill allows you to save on the purchase of a fairly wide line of various additional tools.
One of the interesting areas of application is grinding with a drill. Moreover, the nozzles on the market will allow working with concrete, wood, metal, and plastered surfaces. This topic should be considered in detail.
Electric drill. Kinds
If you recall the old tool, then the cartridge in it changed only with the key.
Modern models are already equipped with quick-release heads.
There are several basic options for such a tool:
- Drums. The impact process of a mechanical property. Designed to work with materials with good strength properties.
- Unstressed. Used for drilling holes in less durable substrates.
- Corner Used in confined spaces.
- Mixers Equipped with additional handles, which gives additional convenience when mixing mortars.
- For diamond drilling.
When choosing a drill, you should pay attention to the main characteristics:
- Power. For domestic purposes, an indicator of 1500 watts is suitable.
- Rotational speed (up to 3000 W typical for electric drills for domestic use).
- Drilling diameter. For home use does not require large parameters.
The larger the range for each value, the more versatile the tool becomes. Everyone selects a drill based on their needs. Someone needs a professional, someone needs a universal one. But one thing is certain: when it is possible to shift the mechanical process onto the “shoulders” of the power tool, no one will refuse to do so. Yes, while also saving a significant amount on the purchase of additional equipment.
Types of grinding work
The versatility of the drill and the variety of nozzles allow it to be used for:
- polishing metal, wooden products, glass, coatings;
- stripping metal from corrosion, old paint (base preparation);
- grinding metal, wood products, glass edges;
- stripping of scale, burr, sag 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, if any difficulties arise, this tool is simply necessary.
Classification of grinding tips
There are a number of modifications of such devices: plate, cup, end, drum, disk, soft, abrasive, fan.
The grinding nozzle for a drill looks similar to interchangeable blocks for specialized machines with the only difference being that instead of a threaded connection, a pin is arranged for fixing in an electric drill chuck. Depending on the size of the tool, power, speed of rotation, dexterity of the worker, the quality of grinding or polishing is found. Some craftsmen come up with additional devices for fixing the drill in working condition, which greatly facilitates the processing of parts.
Each of the above grinding nozzles for drill has in its modification a number of options.
All types and areas of their application should be considered.
Plate
Such a nozzle for grinding is available in two versions - plastic and rubber. The second version of the foundation is considered more popular. With its help, more gentle processing of parts is performed. Consequently, damage due to excessive pressure will be minimized.
The polishing base of such nozzles is covered with sanding paper, which is attached by its sticky 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, manufacturers have provided 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 layer between the emery layer and the base. This helps to avoid large grinding defects.
The scope of application of this device will depend on the size of the granularity and hardness of sandpaper.
This can be a rough and finish treatment of a wooden, metal surface. Another interesting use is sanding walls after plastering or puttying. The process is quite dusty, when working, the use of PPE of the respiratory and visual organs will be required.
Cup
The devices are made in the form of a bowl. It can be brushes with metal bristles, and soft filling, for example, foam rubber. It all depends on the planned work.
Metal brushes are used to clean products from the old layer of paint, rust and for skinning wood. For example, for the texture selection process. The brush loosens the wood fibers, after which the plane is gently polished already with a plate nozzle.
And then stain and varnish are applied. Such items after decoration have a clear woody pattern, texture. Soft filling cup devices are used for fine polishing and stripping.
Disk
We can say that this is a kind of cup nozzles, with the only difference being that the bristles are directed from the center to the edges. That is, the process will be carried out by the end method.
By disk can also be attributed a variety of fan. This is when the petals are attached parallel to the base. These devices are used to strip hard-to-reach areas of products from old finishes, corrosion. To work with such nozzles requires some skill.
Drum
Devices are available in the form of cylinders. The working area is located on the side surface on which sanding paper is worn. It can be infinite and with an end element. Fastening is carried out by means of inflation (rubber and pneumatic blocks) or a fixing bolt.
Such a grinding nozzle for a drill is used for processing metal, wood, glass.
The most relevant application is the skinning of radius holes and end elements.
Fan (petal)
They are a grinding disk, on which a plurality of petals of sandpaper or other abrasive material are glued in a circle . Such devices are used more often for the treatment of wooden surfaces.
There is another option when the petals are fixed in the form of a cylinder. Due to their mobility, the nozzle for
polishing wood is used for geometrically complex parts.
Soft
These nozzles are used for soft polishing products. Made of foam rubber, felt or twisted rope material, leather. Mounted with two washers. Such products are intended for soft polishing of paintwork surfaces, as well as for cleaning debris from surfaces that are vulnerable to abrasion.
End Grinding Wheel
It is available in the form of a cylinder, ball, cone. It is made of grinding stone or soft material. Such elements are used for hard-to-reach places, small parts, even for processing precious metals. The abrasive nozzle on the drill can be used to finish metal, glass surfaces. In fact, the file is replaced, only the speed of skinning is several times greater. Soft is used for polishing.
Grinding stone
This interchangeable block is polished and the errors are removed not only from metal, but also from concrete bases. For example, cleaning sag when working with bulk floors. The size of the abrasive fractions is responsible for the quality of grinding and polishing.
Types of grinding substrates
Depending on the material, a grinding disc is selected. There are several main types:
- Sandpaper. Such material has a wide range of stiffness and grit. The larger the abrasive, the rougher the surface will be sanded. There is also closed and open paper. The first option is used for metal processing, and the second - for wood. In the open version, the distance between the chips is greater, this allows you not to accumulate on the plane of wooden chips, sawdust.
- Soft materials. As already mentioned, this can be foam rubber, felt, twisted rope surface, leather. Nozzles with this material allow you to perform fine polishing work.
- Grinding stone. Another type of abrasive coating that allows you to remove more complex defects from the plane. Such a device can process metal, concrete.
Variants of materials for nozzles and the very variety of devices allow the use of a drill for grinding and polishing various materials, up to and including application in jewelry.
Features of work
As mentioned earlier, an electric drill is a multifunctional tool that can replace a number of other devices. And if you do not have the right nozzle for the drill on sale, you can take a similar one for the grinder and fix it using an adapter.
It is made in the form of a threaded rod.
The main difficulty when grinding with an electric drill is to properly hold the device relative to the polished surface. If you perform work using a grinding wheel of 150 mm, while not observing a clear horizontal direction, then radius marks may appear on the plane. In any case, you should first practice on a rough surface.
Two methods of grinding with an electric drill can be distinguished:
- Holding the tool in weight. The disadvantages of this method have already been announced. Advantages include the ability to polish hard-to-reach places and products with complex geometry.
- Using a fixed drill on a carpentry table. This method is good because now the quality of grinding is improved by fixing the tool, and in some cases the part itself. The disadvantages include the lack of electric drill mobility. You will need to remove it from the fasteners to clean up inaccessible places.
When working with the start button, the rotation speed is adjusted, which means the intensity of grinding or polishing surfaces.
It is recommended that the tool does not overheat. Allow time to cool.
When grinding and polishing it is necessary to use personal protective equipment: glasses, a respirator, gloves. All these PPEs will be able to qualitatively protect the respiratory, hearing, and vision organs from dust, which will be formed in the process of sanding products. This must be done especially when processing glass, stone, metal, wood. Do not ignore the use of personal protective equipment.
Conclusion
A drill is a truly universal tool.
Using it for grinding surfaces is justified in everyday single cases. This is a good alternative to manually sanding surfaces. If intensive use is required over a long period, it is better to buy a separate
grinding machine, the range of models of which is quite wide.
So, we found out what grinding nozzles for a drill exist. The choice of a particular type of product depends on the specific objectives of the work.
