Norton 69078609032 Cut-off Wheel 20 in Aluminum Oxide

Product Description

The NORTON 69078609032 is a large-diameter aluminum oxide cut-off wheel engineered for demanding stationary cutting applications in metal fabrication and industrial service work. Measuring 20 inches in diameter and 5/32 inches thick with a 1-inch arbor hole, this Type 1 (01/41) flat wheel is built for straight, plunge, and parting cuts on ferrous and non-ferrous metals. The resinoid bond holds the aluminum oxide abrasive grain under the high stress of stationary tool use, and both sides are reinforced to resist lateral breakage during operation. Maximum rated speed is 2,710 RPM. This wheel carries the Gemini Long Life designation, indicating an extended abrasive life compared to standard cut-off wheels.

This wheel is sized for stationary cut-off machines and chop saws that accept a 20-inch diameter wheel with a 1-inch bore. It is rated for cutting steel and stainless steel, making it a practical choice for structural steel shops, pipe fabrication facilities, and heavy-equipment maintenance operations. The aluminum oxide grain is well-suited to carbon steel, mild steel, and austenitic stainless steel stock in bar, rod, tube, angle, and flat form. It is not rated for portable angle grinder use — stationary tool mounting is required.

Key Features

• 20-inch diameter with 1-inch arbor hole — sized for stationary cut-off machines
• Aluminum oxide abrasive grain rated for steel and stainless steel cutting
• Resinoid bond for consistent grain release and heat resistance under continuous cutting
• Type 1 (01/41) flat profile for straight parting and plunge cuts
• Both sides reinforced to resist lateral stress and wheel fracture
• Gemini Long Life designation for extended service life versus standard cut-off wheels

Compatibility

Designed for use with stationary cut-off tools and chop saws that accept a 20-inch diameter, 1-inch bore cut-off wheel operating at or below 2,710 RPM. Rated for cutting steel and stainless steel stock.

Installation Notes

Installation and wheel changes must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use — never mount a damaged wheel. Confirm the machine spindle speed does not exceed the 2,710 RPM maximum rating stamped on the wheel.
