Norton 66252922986 Cut-off Wheel 7in Aluminum Oxide 60 Grit

Product Description

The NORTON 66252922986 is a Type 1 resinoid-bonded aluminum oxide cut-off wheel designed for high-speed parting and slotting operations on steel and stainless steel. Measuring 7 inches in diameter with a 1/32-inch thickness and a 1-1/4-inch arbor hole, this thin-kerf wheel delivers clean, precise cuts with minimal material loss. Rated to a maximum of 5460 RPM, it is intended for use with stationary abrasive cutoff machines. The 60-grit aluminum oxide abrasive with an O hardness code and grain structure rating of 8 provides consistent stock removal on ferrous metals. Specification designation is 57A60-O8B.

This cut-off wheel is suited for stationary tool applications in fabrication shops, maintenance facilities, and mechanical contracting environments. Typical uses include cutting bar stock, pipe, angle iron, and structural steel sections. The Type 1 (flat) wheel profile is standard for straight cutoff work on horizontal and vertical cutoff saws. It is appropriate for both mild carbon steel and stainless steel workpieces, making it a versatile option for shops that process multiple ferrous metal types in a single workflow.

Key Features

• 7-inch diameter with 1/32-inch thin-kerf profile for precise, low-waste cuts
• Aluminum oxide abrasive rated at 60 grit for consistent ferrous metal stock removal
• Resinoid bond (Type 1 / 01/41 flat wheel) rated to 5460 RPM maximum
• 1-1/4-inch arbor hole fits standard stationary cutoff machine spindles
• Non-reinforced construction suited for stationary tool use only
• Rated for steel and stainless steel applications per specification 57A60-O8B

Compatibility

Designed for use with stationary abrasive cutoff tools accepting a 7-inch diameter, 1-1/4-inch arbor cut-off wheel. Rated for cutting steel and stainless steel workpieces. Not intended for portable angle grinder use due to non-reinforced construction.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Verify the machine spindle speed does not exceed the 5460 RPM maximum rating marked on the wheel before mounting. Inspect the wheel for cracks or chips before each use and never mount a damaged wheel. Because this is a non-reinforced wheel, it must only be used on stationary equipment and never on handheld grinders.
