This makes it ideal for commercial areas like workshops or residential projects such as outdoor patios and garages. While it has a compact design that allows it to fit through standard, 35-inch doorways, it has a 28-inch working width so you can cover more space quickly and can grind and polish up to your floor’s edge.

Available as both an electric floor grinder and a propane floor grinder, the 2807 improves your productivity and efficiency with a powerful performance. The electric grinder is equipped with a 7.5 HP motor that can operate as a single-phase or three-phase, while the propane option has an 18HP Kawasaki motor.

With a robust motor paired with the adjustable weights, the 2807 can tackle most surface preparation tasks, from light polishing projects on marble, stone, and terrazzo to grinding through heavy coatings and thin-set on concrete.

A Floor Grinder Your Whole Team Can Use

The two tool plates can fit six tools that are designed on counter rotation gears so it glides smoothly across surfaces, even uneven areas. Adding weight plates to the front increases pressure, while its variable speed makes it easy to drive. This improves its performance without adding additional work to the operator, reducing fatigue and improving productivity.
