Aggressive PCD for Carpet Glue Removal Concrete 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.
1.Standard PCD shoes usually have one or two large segments. This tool By having five separate segments, the tool has more leading edges to “catch” and lift the coating. This makes it significantly faster at removing stubborn materials.
• Reduced Friction: Smaller segments create less surface drag than one massive square segment, allowing your grinder to maintain higher RPMs even under heavy loads.
• Aggressive Shredding: It doesn’t just scrape; it effectively shreds the coating into smaller chips, which helps prevent your vacuum system from clogging with large “ribbons” of epoxy or mastic.
2. The Stabilizing Bar (The Middle Guard)
Because five PCDs are incredibly aggressive, the metal-bond bar in the middle is essential for control.The bar functions as a ‘floor’ or depth stop, preventing the five sharp PCDs from diving too deeply into the concrete—a significant risk with high-segment counts. The metal bar aids in pulling heat away from the PCD tips, helping extend the tool’s life during extended use. As the PCDs cut through the coating, the metal bar simultaneously performs a light ‘first-cut’ grind on the concrete, clearing away residue immediately.
3. Best Use for Heavy Coatings (>3mm): Multiple layers of old epoxy, thick waterproof membranes, or pool deck coatings. Difficult Adhesives: Thicker mastics or high-build glues that standard diamonds would simply smear. Uneven Concrete: The multiple points of contact allow the tool to ride over “waves” in the concrete more effectively than a single large segment.
4. Directionality: Like all PCDs, these are directional. You must verify if your machine needs Clockwise (CW) or Counter-Clockwise (CCW) rotation.
