Norton 69078627987 Cut-off Wheel 20in Zirconia Alumina Type 1

Product Description

The NORTON 69078627987 is a 20-inch diameter Type 1 (01/41) cut-off wheel designed for stationary grinders used in heavy-duty cutting applications. Built with a zirconia alumina abrasive grain and a resinoid bond, this wheel delivers aggressive, fast cuts on ferrous and stainless steel. At 5/32 inches thick with a 1-inch arbor hole, it is engineered for precision cutting rather than grinding. Both sides are reinforced for added structural integrity during operation. Maximum rated speed is 2,710 RPM. Licensed HVAC, pipe, and metal fabrication shops rely on this type of wheel for clean, repeatable cuts on structural and process piping materials.

This cut-off wheel is suited for stationary grinder setups in industrial, foundry, and fabrication environments. Its NZ Foundry Free Cut specification indicates it is formulated for use on steel and stainless steel without introducing contaminants that could compromise weld integrity or surface finish. The Type 1 flat profile is the standard configuration for chop saws and stationary cut-off machines. It is a practical choice for pipe fabricators, ironworkers, and maintenance welders working with carbon steel and stainless steel stock.

Key Features

• Zirconia alumina abrasive grain for aggressive, long-lasting cuts on steel and stainless steel
• Resinoid bond with reinforced sides for structural durability at rated speed
• Type 1 (01/41) flat profile — compatible with stationary cut-off and chop saw machines
• NZ Foundry Free Cut specification — suitable where contamination-free cutting is required
• 2,710 RPM maximum rated speed
• 1-inch arbor hole fits standard stationary grinder spindles

Compatibility

Designed for use with stationary grinders. Rated for cutting steel and stainless steel. Verify that the machine spindle speed does not exceed 2,710 RPM and that the arbor accepts a 1-inch hole before mounting.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safe-use guidelines for abrasive wheels. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or chips prior to installation — never mount a damaged wheel. Do not exceed the rated maximum speed of 2,710 RPM under any operating condition.
