GT double row diamond cups for dry or wet grinding of concrete, masonry, stone and similar materials. Jumbo sized diamond segments are welded to a heat-treated HSS core that dissipates heat. These diamond wheels last over 300 times longer than abrasive wheels while creating far less dust. This is not only eco-friendly, but saves hours of down time.
- Double row design is for smoother grinding with longer life.
- 5/8" threaded or 7/8"-5/8" non-threaded arbor fits any hand-held electric or air grinder.
- Wheels are CNC spin balanced for more accurate grinding with minimum vibration and noise.
