Norton 66252840001 Cutoff Wheel 4-1/2 in Aluminum Oxide 36 Grit

Product Description

The NORTON 66252840001 is a Type 01/41 resinoid-bonded aluminum oxide cutoff wheel designed for fast, clean cutting on metal and stainless steel. Measuring 4-1/2 inches in diameter and 0.04 inches thick, this reinforced wheel delivers a thin kerf that reduces material waste and heat buildup at the cut. Rated to 13,580 RPM, it is engineered for use with 4-1/2 inch angle grinders found on virtually every trade job site. The sides are reinforced for added durability under lateral load, and the resinoid bond holds abrasive grain consistently through the cut. Metalworkers, pipefitters, ironworkers, and general contractors rely on this wheel for structural steel and stainless fabrication work.

This wheel fits standard 4-1/2 inch angle grinders with a 7/8 inch arbor. It is suited for cutting carbon steel, structural steel, and stainless steel in both residential and commercial construction, fabrication shops, and maintenance applications. The Norton Metal Right Cut specification indicates it is optimized for right-angle grinder use on metal stock, pipe, rebar, and sheet metal. Each package contains one wheel.
