24 Inch x 1-1/2 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 24 inch diameter MJ wheel is used on a flat lap grinder. The MJ wheel will come with no backing on it. Most customers use a construction adhesive to mount the MJ wheel to and older, used diamond disk for placement on the grinder wheel head.
