Norton 66253043014 Aluminum Oxide Cutoff Wheel 8 in 60 Grit

Product Description

The NORTON 66253043014 is a Type 1 (flat) aluminum oxide resinoid-bonded cutoff wheel designed for straight cutting on stationary grinders. Measuring 8 inches in diameter and 0.035 inches thick with a 1/2 inch arbor hole, it is rated to a maximum of 7,640 RPM. The 60-grit aluminum oxide abrasive and hardness code O provide an aggressive, consistent cut through steel stock. Both sides are reinforced for added structural integrity during high-speed cutting operations. Fabricators, pipefitters, and metalworkers use this wheel for precision parting cuts on ferrous materials in shop or production environments.

This cutoff wheel is suited for stationary grinder setups in fabrication shops, metal service centers, and maintenance facilities. Its Type 1 (01/41) flat profile makes it appropriate for straight, narrow parting cuts on steel bar, pipe, tubing, and structural shapes. The brown resinoid-bonded wheel with specification A60-OBNA2 is optimized for steel applications where a consistent, controlled cut is required. It is sold individually and is intended for professional trade use wherever stationary abrasive cutting is part of the workflow.

Key Features

• 8 inches diameter x 0.035 inches thick x 1/2 inch arbor hole — standard Type 1 flat wheel profile
• 60-grit aluminum oxide abrasive for aggressive cutting on steel
• Resinoid bond with hardness code O for controlled wear and stable cut geometry
• Both sides reinforced for structural integrity at high operating speeds
• 7,640 RPM maximum speed rating — verify machine RPM before mounting
• Specification A60-OBNA2 for reference when matching replacement wheels

Compatibility

Designed for use with stationary grinders that accept a Type 1 cutoff wheel with an 8 inch diameter, 1/2 inch arbor hole, and a machine speed at or below 7,640 RPM. Rated for steel applications.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and de-energize the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never exceed the marked maximum RPM. Wear appropriate PPE including face shield, gloves, and hearing protection during operation.
