Concrete grinders mainly are 2 types, which are walk-behind concrete grinder and hand-held concrete grinder.

Walk-behind Concrete Grinder

These grinders are powerful and come with more speed options compared to hand-held concrete grinders. A range of choices is also available for  walk-behind concrete grinders. For example, restricted or small areas require single disc models. While for larger areas, you can choose between double, triple, and even four disc configurations. More disc configuration means more areas can be covered in a short amount of time.

Metal diamond grinding tools such as Scanmaskin Diamond Grinding Shoe, EZ Change Diamond Grinding Head are often used on walk-behind concrete grinder. They are build for floor surface prep, concrete grinding, coating removal and concrete floor leveling. These metal diamond grinding tools are also available in different diamond segment designs and diamond grits for different grinding applications. They are widely used for a variety of interior residential concrete floor, warehouse commercial concrete floors, exterior concrete floors and sports ground.

Hand-held Concrete Grinder

It is best suited for smaller areas, such as home projects. You can use them for industrial work also if the surface is tight. And for narrow areas such as edge and corner, a hand-held concrete grinder can do the job perfectly. One thing worth mentioning is that a variety of disc attachments is available for hand-held tools. Another additional benefit of hand-held concrete grinders is that dust control will be much easier when you can hook them up to an industrial vac.

And they are ideal for polishing countertops, floor edge, spot repair of concrete, terrazzo, granite, engineered stone, quartz, quartzite, marble.

Diamond grinding cup wheels are often used on hand-held concrete grinder as well. They works efficiently for aggressive material removal, concrete grinding and surface preparation.
