What Is A Concrete Grinder?

A Concrete Grinder can come in many configurations, the most common being a hand-held Hand Grinder or hand-held Angle Grinder, but it may be a specialised tool for countertops or worktops. Angle Grinders and Hand Grinders are small and mobile, and allow one to work on harder-to-reach areas and perform more precise work.

There are also small, medium, and large walk-behind Concrete Grinders for tackling larger projects; there is even riding on Concrete Grinders for industrial projects.

All concrete grinders use some sort of abrasive to grind or polish, such as diamond tools or silicon carbide. The diamond tools used for Concrete Grinding are most commonly diamond grinding cup wheels; other machines may use diamond segments, mounted on various plates, slide-on diamond grinding shoes, and for polishing are usually circular Resin diamond polishing pads.

The use of diamond attachments is the most common type of abrasive used under concrete grinders and comes in many grits that range from 16 grit to the high thousands, although 3,000 grit is considered by the industry as the highest shine possible to apply to a floor surface.
