SIGMA GREEN

Sigma Green is an aggressive grinding wheel with noticeably quiet and smooth grinding action. Our best selling grinding wheel
is the perfect balance of fast grinding, low vibration, and superior finish. The layered grain construction, coarse grain followed
by a second layer of finer grain, gives this wheel the advantage of fast grinding with a superior finish.
