Description
The Weha Pitbull Hybrid Resin Diamond Cup Wheel bridges the gap between aggressive stock removal and chip-free finishing. Where standard metal-bond cup wheels cut fast but risk chipping, and standard resin pads finish smooth but wear quickly, the Pitbull's hybrid resin bond delivers both — aggressive enough to grind, shape, and remove fiber mesh, refined enough to leave a clean, scratch-controlled surface ready for polishing. Mounted on a rigid aluminum backer for stability and low vibration, it runs wet or dry on granite, marble, quartz, engineered stone, porcelain, ceramic, and concrete.
What Makes the Pitbull Different
The hybrid resin bond is harder and longer-lasting than standard resin polishing pads, but uses a diamond matrix that cuts without the micro-chipping risk of metal-bond wheels. The result is a cup wheel that handles demanding fabrication tasks — bevel creation, radius forming, underside smoothing, honed finish creation, fiber mesh removal — with speed and control in a single tool.
Applications
- Edge grinding and shaping
- Bevel and radius creation
- Underside smoothing of countertop overhangs
- Breaking polish to create a honed finish
- Fiber mesh and backing removal
- Surface preparation on granite, quartz, marble, porcelain & concrete
Which Grit to Choose
