JET POWERFLEX Sanding Disc, High Performance Semi Flexible, 5 in Disc Dia, 7/8 in Center Hole, C24 Grit, Coarse Grade, Silicon Carbide Abrasive, Resin Fiber Backing, Type 29 Attachment, Applicable Materials: Concrete, Fiberglass, Hard Building Materials and Stone, 12200 rpm Maximum
Made from extremely sharp silicon carbide grains for fast cutting and long wheel lifeManufactured by attaching multiple layers of silicone carbide to a semi-flexible fiber backingSpiral grooves in the abrasive coating provides quick clearing of ground-off stockMultiple cooling holes reduce the build-up of heat during grinding operations, greatly extending the life of the discThe type 29 convex profile helps prevent gouging of the workpiece and reduces operator fatigue by making it easier to maintain correct grinding angleMount to angle grinders using standard resin fiber disc back-up pads and nuts
