Norton 66253042980 Aluminum Oxide Cutoff Wheel 8in 60G

Product Description

The NORTON 66253042980 is a Type 1 (01/41) aluminum oxide cutoff wheel designed for straight cutting operations on stationary grinders. At 8 inches in diameter and 0.035 inches thick, it delivers clean, fast cuts through steel. The wheel is resinoid-bonded with a 60-grit aluminum oxide abrasive and features reinforced sides for added structural integrity during high-speed operation. With a maximum rated speed of 7,640 RPM and a 1.25-inch arbor hole, it mounts securely on compatible stationary grinder spindles. Licensed abrasive technicians and metalworkers rely on this wheel for ferrous-metal stock cutting in fabrication and maintenance applications.

This cutoff wheel is rated for steel applications and is intended for use on stationary grinders. Its Type 1 flat-wheel profile makes it appropriate for straight, in-line cuts rather than angled or depressed-center work. The 60-grit aluminum oxide grain provides a balance of cut rate and wheel life suited to general steel cutting tasks in fabrication shops, maintenance facilities, and industrial service environments. The brown resinoid bond and hardness code O designation indicate a medium-hard wheel suitable for moderate-pressure, consistent-speed operation.

Key Features

• Type 1 (01/41) flat-wheel profile for straight cutting on stationary grinders
• 60-grit aluminum oxide abrasive rated for steel cutting applications
• Sides reinforced construction for increased integrity at operating speed
• Resinoid bond with hardness code O for consistent cut performance under load
• 7,640 RPM maximum rated speed — verify grinder RPM before mounting
• 1.25-inch arbor hole fits standard stationary grinder spindles

Compatibility

Designed for use with stationary grinders. Rated for cutting steel. Specification code A60-OBNA2. Verify that the grinder spindle speed does not exceed 7,640 RPM before mounting.

Installation Notes

Cutoff wheels of this type are installed and serviced by qualified metalworkers or maintenance technicians. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips before mounting — never use a damaged wheel. Ensure the arbor flange and spindle are clean, and confirm the machine RPM rating does not exceed the 7,640 RPM wheel limit. Follow ANSI B7.1 safe-use guidelines for abrasive wheels when operating.
