Norton 66253117881 Cutoff Wheel 10 in Aluminum Oxide Type 1

Product Description

The NORTON 66253117881 is a Type 1 (01/41) aluminum oxide cutoff wheel designed for stationary tool use in metal cutting applications. At 10 inches in diameter and 0.063 inches thick with a 1-1/4 inch arbor hole, this wheel is engineered for straight, precise parting cuts on steel. It uses a resinoid bond and a non-reinforced construction, rated to a maximum of 3,500 RPM. The aluminum oxide abrasive grain is well-suited to medium-hardness steels. Fabricators, machinists, and metal trade professionals working with stationary cutoff saws or chop saws will find this wheel suited to production and maintenance cutting tasks.

This cutoff wheel is rated for steel applications, specifically medium steels in the Rc 30-50 hardness range, per its ML-310 specification. It is intended for use with stationary tools only, not portable angle grinders. Typical install scenarios include shop fabrication, structural steel cutting, and maintenance operations where a dedicated stationary cutoff machine is used. The non-reinforced, Type 1 flat profile is standard for chop saw and abrasive cutoff machine use.

Key Features

• 10 inch diameter with 0.063 inch thickness for clean, narrow kerf cuts
• 1-1/4 inch arbor hole fits standard stationary cutoff machine spindles
• Aluminum oxide abrasive grain rated for medium steels (Rc 30-50)
• Resinoid bond construction for consistent cut performance
• Non-reinforced Type 1 (01/41) flat wheel profile
• ML-310 specification compliance for abrasive cutoff wheel standards

Compatibility

Designed for use with stationary cutoff tools and abrasive chop saws equipped with a 1-1/4 inch arbor. Rated for cutting medium steels per ML-310 specification. Not intended for portable angle grinder use.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety procedures. Ensure the machine is fully de-energized and the spindle is stationary before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the 3,500 RPM maximum rating stamped on the wheel. Always use the appropriate flanges and guards as required by ANSI B7.1 and the machine manufacturer guidelines.
