Norton 66253410185 Cut-off Wheel 18 in Aluminum Oxide

Product Description

The NORTON 66253410185 is a Type 1 (01/41) aluminum oxide cut-off wheel designed for stationary abrasive cutting equipment. Measuring 18 inches in diameter with a 5/32-inch thickness and a 1-inch arbor hole, this wheel is built for straight, aggressive cuts through ferrous and stainless steel stock. The resinoid bond and reinforced construction on both sides provide structural integrity at the rated maximum speed of 3,015 RPM. It carries the Gemini Free Cut designation, indicating a wheel formulation optimized for reduced heat buildup and faster material removal during sustained cutting operations.

This cut-off wheel is intended for use with stationary cutting tools such as chop saws and cutoff machines found in fabrication shops, mechanical rooms, and industrial job sites. Its aluminum oxide abrasive is well suited for cutting mild steel and stainless steel structural shapes, pipe, bar stock, and angle iron. The 18-inch diameter and low RPM rating make this wheel specific to large-format stationary equipment rather than handheld grinders. Fabricators, pipefitters, and maintenance mechanics working with heavy steel material are the primary users of this wheel size.

Key Features

• 18-inch diameter aluminum oxide abrasive wheel for large stationary cut-off machines
• Resinoid bond with reinforced sides for durability and safe operation at rated speed
• Gemini Free Cut formulation reduces heat buildup during extended cutting passes
• Rated for steel and stainless steel applications
• Type 1 (flat) wheel profile for straight, consistent cuts
• Maximum operating speed of 3,015 RPM — do not exceed

Compatibility

Designed for use with stationary cut-off machines that accept an 18-inch diameter, Type 1 wheel with a 1-inch arbor hole and a maximum operating speed at or above 3,015 RPM. Rated for steel and stainless steel cutting applications.

Installation Notes

Installation and wheel changes must be performed by qualified personnel with the machine fully de-energized and locked out per applicable OSHA lockout/tagout procedures. Inspect the wheel for cracks, chips, or damage before mounting — never use a damaged wheel. Confirm the machine spindle speed does not exceed the wheel's 3,015 RPM maximum rating before operation. Always use the correct flange hardware specified by the machine manufacturer and ensure the arbor hole fits snugly without forcing.
