Norton 69078627989 Cut-off Wheel 20in Aluminum Oxide Type 1

Product Description

The NORTON 69078627989 is a reinforced aluminum oxide cut-off wheel designed for high-demand cutting on steel and stainless steel. At 20 inches in diameter and 5/32 inches thick with a 1 inch arbor hole, this is a large-format wheel intended for stationary grinder setups, not handheld tools. The resinoid bond holds the aluminum oxide abrasive together under the stress of aggressive cuts. Both sides are reinforced, providing structural integrity at the rated maximum of 2710 RPM. Metalworkers, fabricators, and foundry operators use this wheel where consistent, clean cuts on ferrous and non-ferrous stock are required.

This cut-off wheel is rated for use with stationary grinders in industrial and foundry environments. Its Type 1 (flat) wheel profile is the standard configuration for straight cut-off operations. The Foundry Cut All Purpose designation means it is suited for a wide range of cutting tasks across steel and stainless steel workpieces. This size wheel is common in pipe fabrication shops, structural steel operations, and heavy manufacturing settings where productivity and cut quality matter more than portability.

Key Features

• 20 inch diameter aluminum oxide abrasive wheel for stationary grinder use
• Both sides reinforced with resinoid bond for durability under load
• Type 1 (01/41) flat profile for straight cut-off applications
• Rated for steel and stainless steel — Foundry Cut All Purpose designation

• 1 inch arbor hole for standard stationary grinder spindle fitment

Compatibility

Designed for use with stationary grinders. Rated for cutting steel and stainless steel. The 1 inch arbor hole and 20 inch diameter are standard configurations for large stationary cut-off machines in industrial and foundry applications.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and never exceed the rated maximum RPM of 2710. Use the correct arbor flanges and ensure the spindle speed of the machine does not exceed the wheel rating.
