Norton 66243510645 Aluminum Oxide Cut-off Wheel 3 in

Product Description

The NORTON 66243510645 is a Type 1 aluminum oxide cut-off wheel designed for aggressive cutting on steel and stainless steel using die grinders. At 3 inches in diameter and 1/16 inch thick, it produces a narrow kerf and clean cuts in metal stock, pipe, bolts, and sheet material. The wheel is resinoid-bonded with a 36-grit abrasive and reinforced on both sides for added safety at high rotational speeds. Rated to a maximum of 25,465 RPM, it fits standard 1/4-inch arbor die grinders and is part of the NORTON Gemini series, recognized for consistent grain structure and wheel integrity.

This cut-off wheel is suited for metal fabrication shops, maintenance and repair operations, and field service work where a compact die grinder is the primary tool. It handles ferrous and stainless steel cutting tasks in tight access areas where a larger wheel cannot fit. The 3-inch diameter makes it a common choice for cutting threaded rod, sheet metal edges, and welds. Licensed tradespeople in HVAC, plumbing, electrical, and general mechanical service regularly keep this size on hand for job-site metal cutting.

Key Features

• Aluminum oxide abrasive at 36 grit for fast, aggressive cuts on steel and stainless steel
• Type 1 flat wheel profile produces a narrow kerf with minimal material removal
• Resinoid bond provides durability and consistent performance through the cut
• Both sides reinforced for structural integrity at rated speed
• 25,465 maximum RPM rating matches standard die grinder operating speeds
• NORTON Gemini series construction for uniform abrasive grain distribution

Compatibility

Designed for use with die grinders accepting a 1/4-inch arbor. Rated for cutting steel and stainless steel applications. Verify that the tool's maximum RPM rating meets or exceeds the wheel's 25,465 RPM maximum before mounting.

Installation Notes

Cut-off wheels must be mounted and operated by personnel familiar with abrasive wheel safety. Inspect the wheel for cracks or damage before each use and never operate above the marked maximum RPM. Ensure the die grinder is fully powered down and the air supply disconnected before mounting or removing the wheel. Always use appropriate eye and face protection when operating cut-off wheels.
