The 1950 Siaspeed 3-1/8" sanding disc is the versatile all-rounder for high stock removal, perfect surface quality, and long life. Coarse grits use a sharp ceramic and aluminum oxide blend for fast cutting, medium grits use blue-fired semi-friable aluminum oxide for longer life and an excellent finish, and a stearate coating resists clogging to maximize disc life.
