Description
The vibration-dampening cup wheel for smoother grinding and less operator fatigue. The Weha 4" Rubber Diamond Cup Wheel features a specially engineered rubber isolation layer between the diamond body and threaded insert — absorbing vibration at the source before it reaches the grinder and operator. The result is smoother operation, cleaner shaping, improved surface control, and significantly reduced fatigue during extended use.
The rubber core also protects the grinder itself — reduced vibration transmission means less wear on the tool's bearings and motor over time.
Which Grit to Choose
- Coarse Grit — aggressive material removal; use for heavy grinding, leveling, and initial surface prep; maximum stock removal with vibration control
- Medium Grit — intermediate refinement; use after Coarse for controlled smoothing before polishing pads or honing sequences
Where It Fits in the Grinding Sequence
The Rubber Diamond Cup Wheel is the flexible finishing step in the grinding workflow — particularly effective on contoured surfaces and edges where rigid cup wheels lose contact:
- Flap Diamond Cup Wheel — initial polish removal and surface leveling
- Resin Filled Cup Wheel or Blitz Resin Filled — controlled stock removal
- Rubber Diamond Cup Wheel (this product) — vibration-free finish grinding; ideal for contoured edges and curved surfaces
- Polishing pads — final gloss restoration

- 10,000 max RPM — rated for high-speed fabrication environments
Works Well With
- Weha 4" Flap Diamond Cup Wheel — use before the Rubber Cup Wheel for initial aggressive polish removal
- Weha 4" Resin Filled Diamond Cup Wheel — use in the intermediate grinding step before the Rubber Cup Wheel
- Weha Blitz 4" Resin Filled Cup Wheels — high-concentration alternative for the intermediate grinding step
- Weha Pig 350VS Planetary Polisher — for full surface polish restoration after the grinding sequence
- Weha Donkey Face Polish & Inline Polishing Pads — polishing pads for the final gloss sequence after surface prep
