Use PCD tooling for coating and adhesive removal, standard segments for flat surface grinding, trapezoid tooling for fast stock removal and smoother operation, and bush hammer plates for a decorative exposed-aggregate finish. The right choice depends on the substrate and the finish you are targeting.
| Tool Type | Best For | Bond / Grit | Speed |
|---|---|---|---|
| Trapezoid | Aggressive stock removal, flat grinding | Metal bond, 25–60 grit | Fast |
| Standard segment | General grinding and levelling | Metal bond, 30–80 grit | Medium |
| PCD | Epoxy, glue, coatings, paint | PCD inserts | Very fast on coatings |
| Bush hammer | Texture, exposed aggregate, slip resistance | Tungsten / diamond tips | Medium |
A: PCD is designed for coatings, not for grinding the slab itself. Switch to metal-bond tooling once the surface is bare.
A: Trapezoid tooling comes in standard 3-inch, 6-segment and single-head sizes — verify your drive plate pattern.
A: No. Bush hammers texture the surface; segments grind it flat. They serve different finishing goals.
Match the tool to the task: PCD strips coatings, trapezoid and segment tooling grind flat, and bush hammers create texture. For aggressive grinding, the Diamond Trapezoid Grinding Disc (JOY-TP-R3) is a proven choice; for coating removal, see the WerkMaster PCD Tooling for Coating Removing (JOY-WM-PCD1R1).
