Description
Purpose-built for controlled shaping, surface refinement, and polish removal. The Weha 4" Flap Diamond Cup Wheel delivers smooth, vibration-free performance with zero chipping on granite, marble, engineered stone, quartzite, porcelain, ceramic, and concrete. The rigid aluminum backing and precision-balanced design keep the surface flat and controlled throughout the grind.
The flap diamond construction exposes new diamond layers as the top layer wears — maintaining consistent cutting performance and extending working life beyond standard cup wheels.
Which Grit to Choose
- 60 Grit — aggressive material removal; use for heavy polish removal, surface leveling, and preparation for honed or leathered finishes
- 120 Grit — finer finish; use for light surface refinement, smoothing after 60 grit, and preparation for polishing pads
