Norton 66253117829 Cutoff Wheel 9in Aluminum Oxide

Product Description

The NORTON 66253117829 is a Type 1 (01/41) aluminum oxide cutoff wheel designed for stationary tool use in metalworking and fabrication applications. Measuring 9 inches in diameter and 0.063 inches thick with a 1-1/4 inch arbor hole, this non-reinforced, resinoid-bonded wheel is built for straight cutoff work on non-ferrous metals. Rated to a maximum of 5,085 RPM, it is intended for use only on stationary cutting machines operated at or below that speed. Fabricators, machinists, and trade professionals working with aluminum, copper, brass, and similar non-ferrous stock will find this wheel well-suited to bench and pedestal grinder setups.

This cutoff wheel is intended for non-ferrous metal applications in stationary tool configurations. Typical use cases include shop environments where aluminum, copper, or other non-ferrous materials are cut to length or profiled using bench-mounted or pedestal-mounted abrasive cutoff machines. The non-reinforced, Type 1 flat profile allows full face engagement with the workpiece, which is standard for straight plunge cuts. The ML-509 specification designation indicates it meets recognized industry quality standards for abrasive products in this category.

Key Features

• 9 inch diameter with 0.063 inch thickness for precise, narrow kerf cutoff work
• 1-1/4 inch arbor hole fits standard stationary cutoff machine spindles
• Aluminum oxide abrasive grain suited for non-ferrous metal cutting
• Resinoid bond provides consistent grain exposure throughout wheel life
• Type 1 (01/41) flat wheel profile for straight cutoff cuts
• Non-reinforced construction — intended for stationary tools only, not portable angle grinders

Compatibility

Designed for use with stationary cutoff machines accepting a 9 inch diameter, Type 1 wheel with a 1-1/4 inch arbor hole, operating at or below 5,085 RPM. Rated for non-ferrous metal applications only.

Installation Notes

This wheel must be installed and operated only on stationary tools by qualified personnel familiar with abrasive wheel safety. Before mounting, power down and lock out the machine per OSHA lockout/tagout procedures and inspect the wheel for cracks or damage — never use a damaged wheel. Verify the machine spindle speed does not exceed the 5,085 RPM maximum rated speed of this wheel. Do not use this non-reinforced wheel on portable angle grinders or handheld cutting tools.
