Norton 66252922983 Cut-off Wheel 7in Aluminum Oxide Type 1

Product Description

The NORTON 66252922983 is a Type 1 flat cut-off wheel designed for aggressive cutting on steel and stainless steel. It measures 7 inches in diameter and 1/32 inch thick, with a 1-1/4 inch arbor hole. The abrasive material is aluminum oxide at 60 grit, bonded with a resinoid bond for consistent cut performance. This non-reinforced wheel is rated to a maximum of 5460 RPM and carries a grain structure of 8 with an M hardness code, indicating a medium bond hardness suited for general-purpose cutting applications. It is intended for use with stationary grinders in shop or fabrication environments.

This cut-off wheel is used in metal fabrication, maintenance, and repair settings where clean, straight cuts on ferrous and stainless metals are required. It fits stationary grinder setups common in welding shops, mechanical service bays, and industrial maintenance facilities. The 7 inch diameter and thin 1/32 inch profile reduce material loss and heat buildup during cuts. The specification code for this wheel is 57A60-M8B, which identifies the abrasive type, grit, hardness, grain structure, and bond type for reference when reordering or verifying wheel selection.

Key Features

• 7 inch diameter Type 1 flat wheel profile for straight, narrow cuts
• 1/32 inch thickness minimizes kerf width and material waste
• Aluminum oxide abrasive at 60 grit for effective cutting on steel and stainless steel
• Resinoid bond with M hardness code for consistent medium-bond performance
• Rated to 5460 max RPM for use with stationary grinders
• Non-reinforced construction; specification code 57A60-M8B

Compatibility

Designed for use with stationary grinders. Suitable for cutting steel and stainless steel. Verify that the grinder arbor accepts a 1-1/4 inch hole size and does not exceed the 5460 RPM rating of this wheel before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety. Always power down and disconnect the grinder from its power source before mounting or removing a wheel. Confirm the machine RPM rating does not exceed 5460 RPM before use. Inspect the wheel for cracks or damage prior to installation and follow ANSI B7.1 guidelines for safe mounting and use of abrasive wheels.
