PFERD 48494 4-1/2" POLINOX Unitized Disc Med.-Hard T27 (Conical) 5/8-11 SiC Fine (MH) 6SF
PFERD offers a wide range of coated and non-woven abrasive tools for face-down grinding, belt grinding, peripheral grinding, surface conditioning, polishing, and much more.
POLINOX unitized wheels and discs consist of multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. This particular bond results in non-woven products with a very good surface finish, high stock removal
POLINOX unitized discs are used for face-down grinding on variable-speed angle grinders. Especially well-suited to work on larger surfaces. The compressed, non-woven material is bonded to a glass-fabric base.
