30 Inch x 2-3/4 inch Polpur MJ wheel for pumice
Polpur MJ material is an excellent carrier for use with pumice for rough polishing your glass. The small fibers in the extruded urethane give friction to the glass surface and the pore structure of the wheel holds the pumice for easy use. The 30 inch diameter MJ wheel is used on a flat lap grinder.
