Diamond Cup Wheels and Grinding Discs: Concrete Leveling and Surface Preparation
Direct Answer: Diamond cup wheels and grinding discs utilize heavy-duty diamond segments welded to a saucer-shaped steel body for concrete floor leveling, high-spot grinding, and coating removal (epoxy, urethane, mastic). Single-row cups offer fast aggressive stock removal, double-row cups deliver smooth finish grinding, and arrow/PCD segments tear through stubborn rubberized coatings without smearing.

Frequently Asked Questions
What cup wheel segment design is best for removing thick epoxy coatings?
PCD (Polycrystalline Diamond) or Arrow-segment cup wheels are best because they scrape coatings off in chunks rather than heating and smearing the adhesive.
