Norton 66253042983 Cutoff Wheel 8 in Aluminum Oxide 60 Grit

Product Description

The NORTON 66253042983 is a Type 1 (flat) aluminum oxide cutoff wheel designed for straight, precise cutting on stationary grinders. Measuring 8 inches in diameter and 0.06 inches thick with a 1-1/4 inch arbor hole, it runs at a maximum of 7,640 RPM. The 60-grit resinoid bond wheel carries hardness code O and is reinforced on both sides for added strength during high-speed cutting. It meets the A60-OBNA2 specification and is suited for trade professionals working with stationary grinding equipment in fabrication, maintenance, and mechanical service environments.

This cutoff wheel is rated for cutting steel and is intended for use with stationary grinders. The Type 1 flat profile makes it appropriate for straight parting cuts on bar stock, pipe, structural steel, and similar ferrous materials. Its resinoid bond and aluminum oxide abrasive combination deliver consistent cut quality in shop and industrial maintenance settings where stationary equipment is standard. A single wheel is packaged per unit.
