Norton 66253222833 Cut-off Wheel 12in Aluminum Oxide Type 1

Product Description

The NORTON 66253222833 is a Type 1 (01/41) aluminum oxide cut-off wheel designed for aggressive cutting on steel and stainless steel. Measuring 12 inches in diameter with a 1/16 inch thickness and a 1-1/4 inch arbor hole, this wheel is built for use with angle grinders operating up to 3,185 RPM. The aluminum oxide abrasive grain at 90 grit delivers controlled material removal on ferrous and stainless applications. A rubber bond holds the grain structure together across the full cut. This is a non-reinforced wheel rated for straight cutting rather than lateral grinding, and it is typically installed and operated by metalworkers, fabricators, and pipefitters working in shop or field environments.

This cut-off wheel is suited for cutting steel and stainless steel in fabrication, maintenance, and construction applications. Its 12 inch diameter makes it appropriate for larger angle grinders handling structural steel, pipe, and plate. The Type 1 flat profile is intended for straight plunge and cutoff work only. Trade professionals handling pipe fabrication, structural steel work, and general metal cutting will find this wheel fits standard large-bore angle grinder arbors commonly used in those settings.

Compatibility

Designed for use with angle grinders accepting a 1-1/4 inch arbor hole and capable of mounting a 12 inch diameter Type 1 cut-off wheel. Rated for cutting steel and stainless steel per the manufacturer specification 57A90-K4R30.

Installation Notes

This wheel must be mounted and operated by qualified personnel familiar with abrasive wheel safety. Always power down and disconnect the grinder before mounting or removing the wheel. Verify that the grinder spindle speed does not exceed the 3,185 RPM maximum rating marked on the wheel before use. Type 1 wheels are designed for straight cutoff cuts only and must never be used for side grinding or lateral pressure applications, as this is a non-reinforced wheel.
