Rating of the TOP-15 discs for the grinder of 2022: an overview of the best grinding, cutting for metal and diamond models

Without such a tool as a grinder, it is impossible to complete any more or less serious repairs. But she needs an assistant - a nozzle. And you need to choose such nozzles correctly. How - now we will tell.

Bulgarian (technical name angle grinder, angle grinder) used during home repairs, and at construction sites.

The list of technological manipulations that it helps to carry out is long, but let's talk a little about something else, namely: how choose the right nozzles and discs for angle grinders.

They are chosen by appointment. (depending on the material and purpose of the work) and in size.

The assortment in power tool stores is large, but not everyone can approach this issue professionally. It is precisely for such doubters and those who do not understand that our article is designed.

What features of discs for angle grinders to pay attention to when choosing?

There are not so many nuances in this matter (household appliances are much more difficult to choose), so study them properly.

  • Standard sizes of circles.
    The outside diameter of the disc cannot exceed the limits set for your angle grinder.
    Otherwise, the linear speed of the cutting edge will be constantly exceeded, and this is fraught not only with the destruction of the disk itself, but also with significant injuries to the user - after all, the protective cover will have to be removed!
    In addition, a small unit simply does not have enough power for high-quality work.
    There are several standard sizes: 115, 125, 150, 180, 230 mm.
    All the necessary information is printed on the wheel (thickness, diameter, maximum rotation speed, etc.).
  • Appointment.
    They are divided into 4 types: cutting, peeling, grinding and sharpening.
    Cutting discs suitable for metal work (blue, made of crystalline or synthetic corundum); stone, slate and silicate brick (material - silicon cabide, color - green); diamond (for red brick, concrete, ceramic tiles and porcelain stoneware, made of metal with diamond chips in the form of an abrasive mass); on wood (requiring special security measures, as they often slip or bounce).
    Peelers help remove the old layer of paint and rust (they are made in the form of a bowl with bundles of wire of different thicknesses or a disk).
    Grinding - assistants in polishing and grinding wood, metal, plastic and other surfaces.
  • Material.
    Can be abrasive and diamond.
    Diamonds are used in the processing of quartz glass, ceramics, quartz and other durable materials, abrasives work well with metals.
Reference! Do not rush to throw away the old grinder that you inherited from your father: even if its landing diameter does not match the current standards (the current figure is 22.2 mm), you can buy special adapters and use the device without problems.
