Norton 66253322152 Cutoff Wheel 12 in Aluminum Oxide

Product Description

The NORTON 66253322152 is a Type 1 (01/41) flat cutoff wheel designed for stationary abrasive cutting tools. It measures 12 inches in diameter and 0.078 inches thick, with a 1-1/4 inch arbor hole. The wheel is bonded with a resinoid bond and uses aluminum oxide as the abrasive material, making it well suited for aggressive cutting through steel. With a maximum operating speed of 3,820 RPM, this non-reinforced wheel is intended for controlled, fixed-position cutting operations. Metal fabricators, maintenance technicians, and machine shop professionals typically install and use this wheel on stationary cutoff machines.

This cutoff wheel is rated for cutting steel, including hard steels in the Rc 40-55 hardness range. It is designed for use with stationary cutting equipment rather than handheld angle grinders. Typical applications include production cutting of steel bar stock, structural shapes, and hardened steel components where consistent cut quality and controlled operation are required. The wheel meets ML-212 specification standards.

Compatibility

Designed for use with stationary cutoff tools accepting a 12 inch diameter, 1-1/4 inch arbor hole Type 1 cutoff wheel. Rated for steel cutting applications, including hard steels in the Rc 40-55 range per ML-212 specification.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always verify the machine spindle speed does not exceed the 3,820 RPM maximum rating marked on the wheel before mounting. Power down and lock out the machine before changing wheels, and inspect the wheel for cracks or damage prior to installation. Follow ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels.
