3M 7100304009 Cubitrona 3 Cut-off Wheel 4.5 in 36 Grit

Product Description

The 3M 7100304009 Cubitrona 3 Cut-Off Wheel is a high-endurance abrasive wheel engineered for fast, clean cuts across a wide range of metals. It measures 4.5 inches in diameter with a 0.125 inch thickness and carries a 36 plus grit rating. The wheel uses 3M Re-Engineered Precision Shaped Ceramic Grain, a proprietary molecular bonding technology that produces sharp, angular grain structures. These structures continuously fracture to expose fresh cutting edges, allowing the wheel to run cooler, wear more evenly, and cut faster with less applied pressure. Licensed trades workers and fabricators rely on this wheel for demanding production and repair applications.

This cut-off wheel is suited for cutting stainless steel, mild steel, aerospace alloys, autobody sheet metal, marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners. It is designed for use with 4.5 inch angle grinders commonly found in metal fabrication shops, automotive service bays, marine yards, and industrial maintenance environments. The wheel creates perpendicular cuts using its outer edge, making it effective for tight clearance work and precision parting cuts. Minimum order quantity is 2 units per box.

Key Features

• Re-Engineered Precision Shaped Ceramic Grain continuously fractures to maintain sharp cutting edges throughout wheel life
• Delivers up to 10 percent increased cut rate compared to 3M Cubitrona II Performance Abrasives
• Removes up to 3 times more material per wheel compared to 3M Cubitrona II Performance Abrasives, reducing changeover frequency
• Cuts stainless steel, mild steel, aerospace alloys, exhaust components, clamps, and rusted fasteners
• Outer-edge cutting geometry produces perpendicular cuts suitable for sheet metal and tubing applications
• Runs cooler than conventional abrasive grain, reducing heat discoloration and workpiece distortion

Compatibility

Designed for use on 4.5 inch angle grinders. Suitable for cutting stainless steel, mild steel, aerospace alloys, autobody sheet metal, marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners.

Installation Notes

This wheel is installed and operated by qualified metal fabricators, mechanics, or maintenance technicians using a 4.5 inch angle grinder. Before mounting, inspect the wheel for cracks or damage and confirm the grinder guard is properly in place. Always verify the grinder's maximum RPM rating meets or exceeds the wheel's rated speed before use. Wear appropriate PPE including eye protection and a face shield when operating cut-off wheels.
