Norton 66252938788 Cutoff Wheel 7in Aluminum Oxide 60 Grit

Product Description

The NORTON 66252938788 is a Type 1 flat cutoff wheel designed for aggressive cutting on steel. It measures 7 inches in diameter, 0.035 inches thick, and accepts a 1-1/4 inch arbor. The abrasive grain is aluminum oxide bonded with a resinoid bond system and rated at 60 grit for fast material removal. Both sides are fiberglass-reinforced for added durability during stationary grinder use. The wheel is rated to a maximum of 8,730 RPM. It is intended for use by metal fabricators, pipefitters, welders, and maintenance technicians working with stationary grinding equipment.

This cutoff wheel is suited for steel cutting applications in fabrication shops, maintenance facilities, and industrial job sites. It is designed for use with stationary grinders that accept a 7 inch, 1-1/4 inch arbor wheel. The thin 0.035 inch kerf minimizes material loss and heat buildup during cuts, making it a practical choice for repetitive production cutting or precision work on structural steel, pipe, and bar stock.

Key Features

• 0.035 inch thickness delivers a narrow kerf and reduced heat
• Aluminum oxide grain at 60 grit for fast, consistent cuts on steel
• Resinoid bond with sides-reinforced fiberglass construction
• 8,730 RPM maximum speed rating for stationary grinder compatibility
• Hardness code O for controlled wear and extended wheel life

Compatibility

Designed for use with stationary grinders that accept a 7 inch diameter, Type 1 cutoff wheel with a 1-1/4 inch arbor hole. Rated for steel applications per specification A60-OBNA2.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always power down and isolate 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. Ensure the machine arbor size matches the wheel bore and that all flanges and guards are properly seated before operation.
