Norton 66253322153 Cutoff Wheel 12in Aluminum Oxide Type 1

Product Description

The NORTON 66253322153 is a 12-inch diameter Type 1 (01/41) resinoid-bonded aluminum oxide cutoff wheel designed for stationary cutting operations on steel and medium steels. At 0.078 inches thick with a 1-1/4 inch arbor hole, this wheel delivers straight, efficient cutoff cuts when mounted on stationary abrasive cutoff machines. The non-reinforced resinoid bond holds aluminum oxide grain securely during operation, and the wheel is rated to a maximum of 3,820 RPM. It is appropriate for use on medium steels in the Rc 30-30 hardness range and meets ML-312 specification requirements. Trade professionals in metal fabrication, pipefitting, and mechanical contracting use this wheel for production and maintenance cutoff work.

This cutoff wheel is intended for stationary tool use only, not angle grinders or portable equipment. It is suited for ferrous metal cutting applications involving steel structural stock, pipe, bar stock, and similar medium-steel workpieces. The Type 1 flat wheel profile is standard for cutoff service on stationary abrasive saws. The ML-312 specification and Rc 30-30 application rating guide the user to appropriate material hardness ranges where the wheel will perform efficiently and safely.

Installation Notes

Installation and wheel mounting should be performed by a qualified operator familiar with abrasive wheel safety procedures. Always power down and lock out the machine before mounting or removing the wheel. Verify the machine spindle speed does not exceed the 3,820 RPM maximum rating marked on the wheel before operation. This wheel is rated for stationary tools only and must not be used on portable angle grinders or handheld cutting equipment.
