Norton 66243411392 Aluminum Oxide Cutoff Wheel 2in Type 1

Product Description

The NORTON 66243411392 is a Type 1 (flat) aluminum oxide cutoff wheel designed for high-speed parting and slotting cuts on steel and stainless steel. Measuring 2 inches in diameter and 0.035 inches thick with a 1/8 inch arbor hole, this wheel mounts directly on die grinders for precision cutoff work in tight or confined access areas. The resinoid bond and reinforced fiberglass sides handle the lateral stresses common in cutoff applications, and the wheel is rated to a maximum of 30,560 RPM. At 0.02 pounds, it adds virtually no weight to the tool. The Gemini specification line from Norton is formulated for consistent cut performance and extended wheel life on ferrous metals.

This cutoff wheel is suited for trade professionals working in HVAC fabrication, plumbing rough-in, electrical conduit work, and general metal fabrication where a small-diameter cutoff wheel is required. The 2-inch diameter and 1/8 inch hole make it compatible with standard die grinder mandrels. Its thin 0.035 inch kerf reduces material loss and heat buildup during cutting, making it appropriate for both production shop use and field service applications on steel pipe, sheet metal, and stainless steel fittings.

Key Features

• Type 1 (01/41) flat wheel profile — standard geometry for straight parting cuts
• Aluminum oxide abrasive grain — effective on steel and stainless steel
• Resinoid bond with fiberglass reinforcement on both sides for added strength under load
• 0.035 inch thin kerf minimizes heat buildup and material waste
• 30,560 maximum RPM rating for use with high-speed die grinders
• Gemini specification — Norton product line formulated for ferrous metal cutting

Compatibility

Designed for use with die grinders accepting a 1/8 inch arbor. Rated for cutting steel and stainless steel. Verify that the die grinder free speed does not exceed 30,560 RPM before mounting.

Installation Notes

Cutoff wheel mounting and use should follow ANSI B7.1 safety standards and the tool manufacturer guidelines. Always inspect the wheel for cracks or chips before mounting and never operate above the marked maximum RPM. Wear appropriate eye and face protection, and ensure the work piece is secured before beginning the cut. Do not apply side pressure to a Type 1 cutoff wheel — these wheels are designed for straight cutting only.
