POLINOX® PNER Unitized Discs - Threaded Hub
PFERD unitized discs are used for end grinding on angle grinders. The unitized fleece is bonded to a glass woven base. The PNER discs are particularly suitable for working larger areas on stainless steel (INOX) components.
Depressed Center (Type 27) PNER discs with 5/8-11 threaded hub
POLINOX® PNER non-woven tools consist of multiple layer, strongly compressed non-woven material, bonded in a special grit resin system. This bonding system produces non-woven tools with excellent surface finishes, high stock removal and long tool life. Provide medium flexibility when working on soft metals, alloys, high-alloy steels and titanium alloys.
