Types of grinders

This is a tool where the surface is grinded in a unidirectional direction, with the help of grinding sandpaper tape, which is located on the rollers provided for rotation. This kind of tool is suitable for polishing large surfaces.

This type of machine is also called a flat grinder. It is a tool with a flat sole, hence the name. Surface grinding is performed by reciprocating movements of the sandpaper. It is this action that is vibratory in nature. This type of machines also has a vacuum cleaner for collecting construction dust.

To work on the ledges and corners there is another kind of machines of vibrating type, it is a delta sander. The sole of this type of tool has a triangular shape, which allows you to perform work in hard-to-reach places.

Such a variety, it is customary to call orbital. The name again was formed due to the appearance of the grinding pad. It resembles an orbit or, simply put, a circle.

How to choose a tool

First, you must decide for what type and amount of work needed tool, whether it will be a one-time job or the grinder is needed for permanent use in the workshop or production.

If it is a one-time job, after which the grinder is no longer needed, and at hand there is a drill, an electric screwdriver or angle grinder, then it is worth paying attention to the grinding attachments for these tools. If they are suitable for the work, then this way you will save your time and money

When the work is of a periodic nature, and their volume is not great, then it is worth paying attention to the renovator. This tool will not only be able to perform grinding, but will come in handy in the future, t.К

It is indispensable for occasional, small jobs on wood, metal, even tile in hard-to-reach places. In the household, it can replace a bunch of other tools.

If the tool is needed in the workshop for regular work, where both rough sanding and finishing are required, including.Ч. In hard-to-reach places, two or three tools are needed at once:

  • The combination of belt, eccentric and delta sander would be a serious blow to the budget, but could cover all needs at once. The result is fast deburring and fast finishing, as well as the treatment of angles that are inaccessible with previous models.
  • The combination of a surface grinder and delta grinder will not be as effective on a large volume of preparatory work on rough sanding wood, it will take more time.
  • The combination of an eccentric and delta sander will be even slower, but the sanding results will be better.

For occasional carpentry work at home or in the shed or workshop, cheaper models of sanders are suitable. Household machines can be designed for limited intermittent use.

This is why NOBODY will tell YOU this ANGLE GRINDER Hack!

About assembling a homemade device is worth thinking only if you have your own workshop or shed, where there are all the necessary materials, as well as a place to install the tool. You also need a lot of time, patience, and understanding of what you need it for.

Important Features

Characteristics you need to pay attention to when choosing:

Power consumption, as it determines the performance. In this case, the power is compared between models, not between types of machines. Whether the machine has a built-in dust extraction system on the soleplate, an outlet for connecting a vacuum cleaner. Without it, dust particles will interfere: spoil the surface of the product, get clogged in the abrasive, reducing the effectiveness of the work. The more holes on the sole. The better, they should be evenly spaced over its entire area. The longer the power cord, the better

An extension cord compensates for this drawback, but it is not very convenient to lug around on a cord a box with a socket. Handles must rest comfortably in the hand and rubber pads are used for this. All buttons should be easy to access and lie flat on the handlebar so you don’t have to intercept the buttons to operate them. Note the weight. A lightweight tool is comfortable to handle vertically

Heavy models are easier to control. Have a “soft start” function. When the speed is set gradually. It depends on the tool life, it is also more pleasant when the tool starts working smoothly, rather than jerk. Must be able to adjust the number of revolutions. For grinding, use a large number of revolutions, but there are places where you want to accurately process the surface of the product at low revolutions. Overheat protection feature extends the life of the unit. In models with clips for sandpaper, you need to check whether they are conveniently located, whether they click easily. Replacing the abrasive blade should not be a problem.


Angle grinder was originally created for grinding surfaces. But due to significant design upgrades, it quickly enough began to perform such useful functions as cutting and processing all kinds of building materials, including cement, concrete, brick, tile, slate and all types of metals.

According to the way the work is done, the angle grinder, as well as all power tools, are created to operate in one of two modes:

  • Constant work in the conditions of construction with the overcoming of the maximum loads during a full work shift. Professional models;
  • For single use with the organization of breaks at rated loads. Household tool.

This is one of the important differences to consider when buying. It affects the cost of the angle grinder.

Even the plastic composition of the body is chosen so that when heated to 140 ° C does not transfer high temperatures to the hands of the operator, while at the same time did not lose its strength.

  • Vibration protection inserts on the handles to prevent the development of occupational diseases;
  • SDS quick lock nuts which allow you to install the working parts without using a special wrench;
  • Swivel back handle;
  • Swivel function of the gearbox or possibility to change the front handle in one of three positions;
  • Special design of the bearings, which ensure the balance of the tool;
  • Long power cord with protective layer of solid insulation;
  • The ability to regulate the rotation speed of the working wheel and a number of other useful functions.
