The Precision Scraper for Sensitive Substrates
"The primary failure in coating removal is 'Galling'—where high-speed friction melts sticky glue into the tool. At Supreme Diamond Tools, we engineered our Standard PCD Series to act as a precision scraper. Unlike our aggressive 'Studded Aggressor' wheels that shatter concrete, these 1/4 PCD chips are designed to slice and shave away coatings with 'cold-cutting' action. This prevents smearing and protects the concrete substrate from unnecessary damage, providing the perfect profile for thin-set reapplications."
— The Supreme Diamond Engineering Team
The Supreme Professional Standard PCD Cup Wheel is the contractor's first choice for removing "gummy" or "sticky" materials. Featuring high-grade 1/4 PCD (Polycrystalline Diamond) chips, this wheel slices through epoxy, polyurethane, and adhesives rather than grinding them, ensuring your machine stays productive without the frustration of tool clogging.

Watch for Nails and Fasteners: PCD (Polycrystalline Diamond) is the hardest man-made material, but it is also brittle. If your cut path strikes a metal screw, bolt, or concrete anchor, it can fracture the PCD chip. Always sweep the floor for protruding metal before starting. If you must remove coating over metal, slow your RPM and use a light touch to preserve the shaving edge.
