Sigma Green

Part Number: 730000

Our best selling grinding wheel is the perfect balance of fast grinding, low vibration, and superior finish. Sigma Green Grinding Wheels are fast grinding wheels manufactured with a specialty grain and bond combination. Sigma Green is constructed with a layer of coarse grain and a second layer of finer grain, resulting in a better finish compared to standard “fast grinding” wheels. The specialty bond also results in a better balanced, noticeably quieter, and much smoother running grinding wheel, with less chatter and less vibration.
