Description
Smooth, controlled grinding without the bounce. The Weha 4" Resin Filled Diamond Cup Wheel is engineered for chip-free grinding and honing on granite, marble, engineered stone, and other natural stone materials. The resin-filled design eliminates the aggressive biting and bouncing common with standard cup wheels — delivering faster cutting with better surface control and cleaner edges.
Strategically placed diamond segments maximize cutting speed and efficiency, while the perfectly balanced design ensures stable, vibration-free operation throughout the grind.
Which Grit to Choose
- Coarse — aggressive stock removal; use for heavy grinding, leveling uneven surfaces, and initial surface prep after cutting
- Medium — intermediate refinement; use after Coarse to smooth the surface before moving to Fine or polishing pads
- Fine — controlled finish grinding; use for final surface prep before polishing or honing sequences
Where It Fits in the Grinding Sequence
The Resin Filled Cup Wheel sits in the middle of the grinding workflow — after aggressive diamond cup wheels and before polishing pads:
- Flap Diamond Cup Wheel (60 or 120 grit) — initial polish removal and surface leveling
- Resin Filled Cup Wheel (this product) — Coarse → Medium → Fine for controlled stock removal and surface refinement
- Rubber Diamond Cup Wheel — flexible finish grinding on contoured surfaces
- Polishing pads — final gloss restoration
