Polpur MTV Cone for Pumice

Polpur's MTV material is made specifically for working with pumice on your glass and the 60 degree cone is an excellent way to clean up interior bevels on open ended glass pieces. Cones are available in 5/8-11 threading for use with Covington flat lap grinders and WaterJet Design flat lap grinders and in 1"-14 for threading onto lathe spindles for use on cutting lathes.
