Pferd Polinox® Unitized Disc, 4-1/2" x 1/2 x 5/8-11, T27, Fine ,Soft, 3SF, Silicon carbide

POLINOX® unitized discs are used for face-down grinding with variable speed angle grinders. Ideal for larger surfaces. The compressed, non-woven material is bonded to a fiberglass back. POLINOX® unitized discs are made of multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. The different combinations of compression, fibers, grain, and the appropriate bond create non-woven products that offer a very good surface finish, high stock removal rate and long tool life. These tools can be used for a wide range of work on surfaces, from relatively coarse grinding to preparing the surface for polishing. Medium-hard version with increased edge strength and service life for coarse blending and polishing tasks. Good for working on edges.
