Norton 66243522372 Cut-off Wheel 2.5 in Aluminum Oxide

Product Description

The NORTON 66243522372 is an aluminum oxide cut-off wheel designed for aggressive cutting on steel and stainless steel using die grinders. Built to a Type 1 (flat) profile, it measures 2.5 inches in diameter and 1/16 inch thick, with a 3/8 inch arbor hole. The resinoid bond and reinforced construction keep the wheel intact under the rotational stress of high-speed cutting. At a maximum rated speed of 30,560 RPM and a 70-grit grain, this wheel delivers fast, controlled material removal on ferrous and stainless workpieces. Weighing just 0.05 pounds, it is a compact consumable suited for tight-access cutting tasks in fabrication, maintenance, and field service work.

This cut-off wheel is sized for use with die grinders and similar small-arbor rotary tools. The 2.5 inch diameter makes it well-suited for cutting bolts, rods, pipe, sheet metal, and weld flash in confined spaces where larger wheels cannot reach. The aluminum oxide abrasive and resinoid bond perform reliably on carbon steel and stainless steel, making it a practical choice for HVAC fabricators, pipefitters, maintenance technicians, and metal shop workers who need a compact cutting wheel for detail or access work.

Key Features

• Aluminum oxide abrasive with resinoid bond for consistent cut performance on steel and stainless steel
• Type 1 flat profile optimized for straight cut-off applications
• Sides reinforced for added structural integrity during high-speed use
• Rated to 30,560 RPM for compatibility with standard die grinder speeds
• Compact 2.5 inch diameter accesses tight spaces where larger wheels cannot fit
• 70-grit grain balances cut speed and wheel life on ferrous materials

Compatibility

Designed for use with die grinders accepting a 3/8 inch arbor. Suitable for cutting carbon steel and stainless steel workpieces.

Installation Notes

Cut-off wheels must be installed and operated by personnel familiar with abrasive wheel safety. Always verify that the tool's rated RPM meets or exceeds the wheel's maximum RPM rating of 30,560 before mounting. Inspect the wheel for cracks or chips before each use and never use a damaged wheel. Wear appropriate eye, face, and hand protection, and ensure guards are in place before operating the grinder.
