Norton 66252838455 Ceramic Alumina Cut-off Wheel 4-1/2 in

Product Description

The NORTON 66252838455 is a Type 1 ceramic alumina cut-off wheel designed for aggressive material removal on steel and stainless steel. Measuring 4-1/2 inches in diameter and 1/16 inch thick with a 7/8 inch arbor hole, this wheel mounts directly on standard angle grinders. The ceramic alumina abrasive at 36 grit delivers fast, cool cutting action that extends wheel life compared to conventional aluminum oxide. A resinoid bond with reinforced sides provides structural integrity at speeds up to 13,580 RPM. Fabricators, pipefitters, and maintenance technicians reach for this wheel when working on ferrous and stainless steel stock.

This wheel is suited for cutting operations on steel and stainless steel in both shop and field environments. The 4-1/2 inch diameter and 7/8 inch arbor fit the most common small angle grinders used in fabrication, mechanical contracting, and industrial maintenance. The Quantum3 specification designation reflects NORTON engineering standards for cutting performance and wheel consistency. It is sold individually but requires a minimum order quantity of 25 units.
