Grinder selection: basic parameters and their influence

The abundance of grinders confuses those buyers who rarely have to deal with construction tools. The task is complicated by the fact that visually similar devices often have completely different designs and are suitable for solving fundamentally different tasks.

Although all grinders are designed for grinding and deburring, their uses may vary. In order not to make a mistake with the choice and purchase the grinder that is suitable for solving specific tasks, it is advisable to pay attention to 5 characteristics that affect the operation process.

Manufacturer

The developer is another criterion from which to start in the selection process. The following characteristics depend on the good faith of the manufacturer:

  1. instrument quality,
  2. functionality and performance,
  3. durability,
  4. security.

In order to avoid unpleasant incidents during use, you should give priority to the development of brands with a positive reputation. Among them: Bosch, Makita, Ryobi and many others.

Variety

There are four types of grinders. By type of construction, devices are divided:

  • for corners,
  • tape,
  • straight,
  • vibrating.

Models with angular configuration are more common. They are called grinders. Such devices are suitable for rough grinding, polishing and cutting various materials.

Devices with tape are designed for rough surface treatment. Their advantage is the ability to perform large volumes of work. They easily remove rust, blackening, thick layers of paint.

Straight grinders are convenient to use in workshops for the manufacture of furniture from metal products. They use small burrs (different shapes of abrasive bits), so they can easily find their way into hard-to-reach places.

It is advisable to buy vibrating tools for finishing. They do not leave dents or marks from the working surface, so they help a lot in the final stages of construction and repair.

Power

The performance of a grinder motor determines efficiency and effectiveness. However, this does not mean that choosing a tool should be based on the principle “the more powerful the better”. For household use, you should not buy an expensive model with a 1000 or 2000 W motor.

In the process of doing simple household tasks, you will hardly be able to experience all its benefits in practice. It is advisable to purchase such a grinder for a workshop. At home, power from 200 to 750 W is quite enough.

Nutrition

Grinding machines of the network type successfully solve those tasks for which top performance and precision of grinding are important, but at the same time mobility fades into the background.

Important: The range of the power tool can be increased by using an extension cord.

Battery models work without being tied to an outlet. They are better at coping with those jobs in which the user must actively move.

Work surface area

The size of the sanding belt, blade or disc determines the speed at which tasks are completed. Therefore, for processing large products, it is worth using devices with the largest grinding attachments (grinders, vibration models). They allow you to reduce the number of roughing passes and get closer to the desired result faster.

Additional Features

The process of using grinding machines is influenced by the presence of:

  • functions for adjusting the speed of rotation of the working surface,
  • protection mechanisms against accidental activation and overload,
  • additional handle for easy fixation,
  • transport case as standard.

Another feature for comfortable work is the built-in dust collector.
