Norton 66253149317 Cutoff Wheel 10 in 60 Grit Aluminum Oxide

Product Description

The NORTON 66253149317 is a Type 1 flat aluminum oxide cutoff wheel built for stationary grinder applications. Measuring 10 inches in diameter with a 0.0600 inch thickness and a 5/8 inch arbor hole, it delivers a narrow, clean cut path on steel. The resinoid bond and reinforced side construction hold the abrasive grain firmly during aggressive cuts, while the 60-grit aluminum oxide abrasive provides an efficient balance of cut rate and wheel life. Rated to a maximum of 6,110 RPM, this wheel is sized for stationary cutting machines and is installed by metalworkers, fabricators, and maintenance trades performing production or shop cutting tasks.

This cutoff wheel is designed for cutting steel in stationary grinder setups, making it a practical choice for fabrication shops, maintenance facilities, and industrial workspaces. Its Type 1 (flat) profile suits applications where straight, plunge-style cuts are required. The 60-grit rating and aluminum oxide abrasive are well matched to ferrous metal stock removal rather than finishing work. Per the manufacturer specification A60-OBNA2, this wheel carries hardness code O, indicating a medium-hard bond that resists breakdown under sustained cutting pressure while still releasing worn grain to expose fresh cutting edges.

Key Features

• 10 inch diameter, 0.0600 inch thickness for narrow kerf cuts on steel
• Aluminum oxide abrasive at 60 grit for efficient ferrous metal cutting
• Resinoid bond with both sides reinforced for structural integrity during operation
• Type 1 flat wheel profile compatible with stationary grinder spindles
• 5/8 inch arbor hole for standard stationary grinder mounting
• Manufacturer spec code A60-OBNA2, hardness code O

Compatibility

Designed for use with stationary grinders. Rated for steel cutting applications. Verify that the machine spindle speed does not exceed 6,110 RPM and that the arbor accepts a 5/8 inch hole before installation.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer guidelines and ANSI B7.1 safety standards for abrasive wheel mounting. Always power down and de-energize the machine completely before changing wheels. Inspect the wheel for cracks or chips before mounting and never exceed the maximum rated RPM of 6,110. A ring test should be performed prior to installation, and the proper flanges and blotter papers must be used to ensure safe wheel retention.
