7" Cup Wheel, 12 Segment - 1/8" PCD

- Aggressive PCD cup wheel for hand-grinder coating removal — the cup-wheel version of the same PCD technology used in floor-grinder Piranha tools, packaged for 7" angle grinders. The 12 polycrystalline diamond segments scrape and rip surface coatings off the substrate rather than grinding them away, removing epoxy, urethane, mastic, glue, paint, thin-set, and waterproofing membranes much faster than a metal-bond cup wheel can.

- 1/8" PCD configuration for fine-cut scraping — the 1/8" designation refers to the depth of the PCD scraping bite. This finer cut handles thinner coatings, paint, and adhesive residue without gouging the slab as severely as larger PCD profiles would. For thicker coatings (over 3mm) and heavier urethane, a deeper-cut PCD removes material faster but leaves a more aggressive scratch pattern to clean up afterward.

- Built specifically for edges, corners, and detail prep — the 7" cup-wheel format is the right answer for places a walk-behind PCD grinder can't reach: perimeters, around columns, on stair treads, in tight commercial spaces, and on vertical surfaces. Lets a contractor strip an entire coating system with one technology — PCD walk-behind for the field, PCD cup wheel for the edges — without switching to a different scratch profile at the perimeter.

- Scraping action prevents segment gumming — the PCD design's signature advantage over standard diamond cup wheels: the scraping action lifts and clears coating debris rather than smearing it across the segments. Standard diamond cup wheels load up and stop cutting when tackling sticky materials like urethane or carpet adhesive; PCD keeps cutting at full speed. Suitable for both wet and dry use on concrete, tile, and asphalt.

- Plan for follow-up grinding to clean up the PCD scratch pattern — PCDs cut aggressively and leave a deep scratch pattern in the concrete underneath the coating. Always plan a follow-up metal-bond grinding pass (typically starting at 16 or 25 grit) before progressing through standard prep or polishing — or before coating application, since most coatings won't bond properly to a raw PCD profile. Best paired with a dust shroud + HEPA vacuum for OSHA silica compliance (29 CFR 1926.1153) during indoor work. Always verify the wheel's stamped max RPM against your grinder's rated speed.
