The 100 Grit Diamabrush Spring Tool 8" is perfect for light profiling of concrete and sanding a top-coat for refinishing.  The diamond grit is bonded to a metallic backing and assembled to a flexible, spring-steel blade. The flexible blade allows the diamond to remain in constant contact with the floor, maximizing the tool's effectiveness. ­

The 100 Grit Diamabrush Spring Tool 8" is combatable with the OF20 series machines.  

It is also designed with replaceable blades to minimize downtime and maximize production. When the blades get worn, just replace them with the replacement kit. The blades are easy to remove and reattach with existing hardware.
