Norton 66253042979 Aluminum Oxide Cutoff Wheel 8 in 60 Grit

Product Description

The NORTON 66253042979 is a Type 1 (flat) resinoid-bonded aluminum oxide cutoff wheel designed for ferrous metal and steel cutting applications. Measuring 8 inches in diameter and 0.035 inches thick with a 5/8-inch arbor hole, this wheel operates at a maximum rated speed of 7,640 RPM. The 60-grit aluminum oxide abrasive delivers consistent stock removal on steel, while the reinforced construction — with sides reinforced — provides structural integrity under lateral cutting loads. At 0.3 pounds, it is a standard single-wheel package suited for trade use on circular saws and compatible stationary or portable cutting equipment.

This cutoff wheel is intended for cutting steel and similar ferrous materials in fabrication, mechanical, and maintenance applications. Its Type 1 flat profile makes it appropriate for straight, plunge, and chop-cut operations. It is installed and used by metal fabricators, pipefitters, millwrights, and maintenance technicians who require a reliable abrasive wheel for production or field cutting tasks. The resinoid bond performs well across a range of steel cutting scenarios where a thin kerf and controlled cut are priorities.

Key Features

• Type 1 (01/41) flat wheel profile for straight and chop-cut applications
• 60-grit aluminum oxide abrasive rated for steel cutting
• Resinoid bond with hardness code O for consistent wheel wear
• Both sides reinforced for structural integrity under load
• 0.035-inch thickness for a thin kerf and reduced material loss
• Maximum rated speed of 7,640 RPM

Compatibility

Designed for use with circular saws accepting a 5/8-inch arbor and capable of operating at or below 7,640 RPM. Verify that the host tool's rated speed does not exceed the wheel's maximum RPM before installation.

Installation Notes

Installation and use of abrasive cutoff wheels should be performed by trained personnel following ANSI B7.1 safety standards. Always confirm the tool's spindle speed does not exceed the wheel's 7,640 RPM maximum rating before mounting. Inspect the wheel for cracks or damage prior to each use, and never use a damaged wheel. Wear appropriate personal protective equipment including a face shield, gloves, and hearing protection during operation.
