Norton 66253122821 Cut-off Wheel 10 in Steel

Product Description

The NORTON 66253122821 is a Type 1 (01/41) aluminum oxide cut-off wheel designed for aggressive cutting of steel and stainless steel. At 10 inches in diameter and 1/16 inch thick, it delivers a narrow kerf and clean cuts on ferrous and non-ferrous work materials. The rubber bond and 90-grit aluminum oxide grain make this wheel well-suited for high-contact cutting tasks on angle grinders. With a maximum operating speed of 3820 RPM and a 1-1/4 inch arbor hole, it mounts directly to compatible right-angle grinders used in fabrication, maintenance, and metal trades.

This cut-off wheel is used in metal fabrication shops, pipe fitting, structural steel work, and general maintenance applications. It handles straight cuts on steel plate, pipe, bar stock, and stainless steel components. The non-reinforced construction and Type 1 flat profile make it appropriate for straight, plunge, and chop-style cuts where a thin wheel is preferred. Licensed tradespeople including pipefitters, ironworkers, millwrights, and maintenance mechanics are the primary installers and operators of this product.

Installation Notes

Mount and operate this wheel only on angle grinders rated for the wheel diameter and maximum RPM shown on the wheel blotter. Always inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Ensure the machine guard is properly positioned before powering on. Follow ANSI B7.1 and all applicable workplace safety standards when handling abrasive wheels.
