Economy PCD with 2 Segments and Sacrificial Bars on trapezoid Quick Change holder 

PCD WITH Sacrificial Bars or Metal Bond Button are less aggressive so they do not damage the concrete. The sacrificial bars or the metal button act as a stabilizer and depth guide, and reduce the gauging of the floor caused by the aggressive pcd segments. These tools are suitable for removal of medium to thin mastics or glues, and failing epoxy coatings (30 mils or less).

PCDs are direction specific tools – use the BLACK PCD tools for Electric grinders with the exception of 32″ Elite models, and the BLUE PCD tools for Propane grinders and 32″ electric Elite models. 

Recommended RPMs – 550-650 rpm for electric machines, 1800-2100 rpm for propane machines.
