Norton 66253322151 Cutoff Wheel 12in Aluminum Oxide Type 1

Product Description

The NORTON 66253322151 is a 12-inch diameter Type 1 (01/41) resinoid-bonded aluminum oxide cutoff wheel designed for use with stationary cutting tools. At 5/64 inches (0.0780 inches) thick with a 1-1/4 inch arbor hole, this wheel delivers straight, narrow cuts on steel and very hard steel applications ranging from Rc 55 to Rc 68 on the Rockwell hardness scale. Rated to a maximum of 3,820 RPM, it is engineered for controlled material removal in demanding fabrication and maintenance environments. Licensed HVAC fabricators, pipefitters, ironworkers, and metal fabrication shops are the typical users.

This cutoff wheel is suited for stationary abrasive saws and chop saws used in metal fabrication shops, maintenance facilities, and trade service environments. Its aluminum oxide abrasive and resinoid bond are well matched to ferrous metals, particularly high-hardness steels in the Rc 55 to Rc 68 range. The Type 1 flat profile makes it appropriate for straight, plunge, and cutoff operations on stationary equipment rather than angle grinders or portable tools.

Key Features

• Aluminum oxide abrasive engineered for ferrous metals and very hard steels (Rc 55-68)
• Type 1 (01/41) flat wheel profile for straight cutoff operations on stationary tools
• Resinoid bond provides controlled cut rate and wheel integrity under load
• 3,820 RPM maximum speed rating for stationary saw applications
• Meets ML-112 specification
• Non-reinforced construction at 0.0780 inches thick for narrow kerf cuts

Compatibility

Designed for use with stationary abrasive cutting tools. Rated for steel and very hard steel applications (Rc 55-68). Verify that the host machine spindle speed does not exceed 3,820 RPM and that the arbor accepts a 1-1/4 inch bore before mounting.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never operate above the rated maximum RPM. Eye protection, face shields, and appropriate PPE are required during operation.
