Weha 4" Rubber Diamond Cup Wheel

The Weha Rubber Diamond Cup Wheel is engineered for ultra-smooth grinding with significantly reduced vibration. Designed with traditional diamond segments and a specially engineered rubber isolation layer between the diamond body and threaded insert, this cup wheel absorbs vibration at the source — delivering smoother operation and greater operator comfort.

The rubber core design minimizes chatter and tool bounce, resulting in cleaner shaping, improved surface control, and reduced fatigue during extended use. Ideal for granite, marble, quartzite, engineered stone, and other natural materials, this cup wheel offers reliable performance for both aggressive grinding and controlled material removal.

Built for durability and balance, the Weha Rubber Diamond Cup Wheel can be used wet or dry and is rated for high-speed fabrication environments.
