The 8 Best Concrete Grinders – Guide

Especially in renovation and restoration work, concrete grinders are needed to grind down surfaces such as concrete, plaster or screed. Here you can find out which drive power is required for your purposes and much more.

We have summarized all the important information for you in a checklist . You can find a selection of practical concrete grinders in our product recommendations.

Checklist For Concrete Grinder

Design
  • Hand-held concrete grinders are available in a so-called tower shape or in the angle grinder shape. In the tower shape, the drive motor sits vertically above the grinding plate. The handles are mounted on the right and left.
  • With concrete grinders in angle grinder form, the motor sits at right angles to the grinding plate. The grinder is held by a handle and the rear end of the drive motor.
Grinding Disc Diameter
  • You can get concrete grinders for grinding wheels with diameters of 115, 125, 150, 180 and 230 mm. The larger the surface to be ground, the larger the grinding wheel diameter should be. For occasional and smaller work, for example, on a staircase or poured walls in preparation for tiling, a concrete grinder with a 115 or 125 mm grinding wheel is sufficient.
  • For larger jobs, for example, if you want to completely grind a new screed in a basement room, you should choose the largest possible grinding wheel and a strong concrete grinder.
Motor Power
  • A concrete grinder must have enough power so that you can work quickly. The motor should not be less than about 800 watts. Higher motor powers of 1,400 to 1,500 watts are better.
  • As a rule, the higher the motor power, the heavier the machine.
  • Concrete grinders with a motor power of 800 to 1,000 watts weigh about 2.5 to 3 kg. More powerful grinders can weigh up to 4.5 kg .
Grinding Wheel Material
  • Only diamond-studded grinding wheels are suitable for grinding concrete. The hard mineral components of concrete ensure that grinding wheels made of other materials wear out very quickly. Diamond grinding wheels last a very long time.
Accessories
  • An important accessory for a concrete grinder is an exhaust hood that can be connected to a vacuum cleaner. The grinding dust is very fine and potentially hazardous to health.
  • Also included should be one or two grinding wheels. A storage and transport case is practical, with which you can transport the machine and all accessories to the place of use and store the concrete grinder protected when not in use.
