Norton 66253042981 Aluminum Oxide Cutoff Wheel 8 in 60 Grit

Product Description

The NORTON 66253042981 is a Type 1 (flat profile) resinoid-bonded aluminum oxide cutoff wheel designed for cutting steel in industrial and trade applications. Measuring 8 inches in diameter and 0.06 inches thick with a 5/8 inch arbor hole, this wheel operates at a maximum of 7,640 RPM and is rated at 60 grit for aggressive stock removal on ferrous material. Both sides are reinforced for added structural integrity during high-speed cutting operations. The brown aluminum oxide abrasive compound with an O hardness code and A60-OBNA2 specification makes this wheel a reliable choice for repeated straight cuts on steel pipe, bar stock, and structural material.

This cutoff wheel is suited for use with circular saws equipped with a 5/8 inch arbor. It is intended for cutting steel in fabrication shops, mechanical rooms, and field service environments. Typical users include pipefitters, ironworkers, millwrights, and general tradespeople who need a consistent, straight cutoff wheel for ferrous metal work. The Type 1 flat wheel profile is the standard configuration for straight cutting rather than grooving or notching.

Installation Notes

This wheel must be mounted and used only on tools whose rated speed meets or exceeds the 7,640 RPM maximum marked on the wheel. Inspect the wheel for cracks or chips before each use and do not use a damaged wheel. Ensure the arbor flange and nut are properly tightened before operation, and always use appropriate guards per ANSI B7.1 or applicable safety standards. Personal protective equipment including eye protection and a face shield is required during cutting operations.
