Trapezoid 3piece of half PCD and 1 Button Grinding Disc / diamond grinding shoes / grinding block is typically used in floor grinders for grinding concrete, terrazzo, or stone surfaces, removing old coatings, epoxy resins, and adhesives, as well as leveling uneven areas.
• Application: Suitable for the first stage of concrete surface pre-treatment, coarse grinding, and polishing. The dot or bar design helps quickly start the grinding process and improve cutting efficiency.
• Features an aggressive diamond segment that serves as both a stabilizer and depth guide, allowing it to scrape even the thickest coatings aggressively before transitioning to a conventional grind—all in a single pass. These PCDs are direction-specific and are available in both clockwise and counterclockwise orientations.
• Working type: Dry grinding / Wet grinding
