3M 7100304008 Cut-off Wheel 4.5 in 0.045 in 36 Plus Grit

Product Description

The 3M 7100304008 is a 4.5-inch diameter abrasive cut-off wheel designed for fast, accurate cutting across a wide range of metals and alloys. Built around 3M Precision Shaped Ceramic Grain, the wheel continuously fractures during use to expose fresh, sharp cutting points. This design promotes cooler running, even wear, and consistent cut rates over the life of the wheel. At 0.045 inches thick with a 36 plus grit rating, it delivers a narrow kerf suited to precision work in fabrication, maintenance, and repair environments. Licensed tradespeople and skilled fabricators in metal-intensive industries are the primary users.

This cut-off wheel is suited for use on 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 angle grinders and compatible cut-off tools where perpendicular cuts are required using the outer edge of the wheel. Applications span automotive, marine, aerospace, and general industrial fabrication and maintenance settings.

Key Features

• 4.5-inch diameter, 0.045-inch thickness for a narrow, precise kerf on metal cutting tasks
• 3M Precision Shaped Ceramic Grain fractures continuously to maintain sharp cutting points and run cooler than conventional abrasives
• Up to 10 percent faster cut rate compared to 3M Cubitrona II Performance Abrasives, reducing operator pressure and cycle time
• Removes up to 3 times more material per wheel compared to 3M Cubitrona II Performance Abrasives, reducing changeover frequency
• Compatible with a broad range of metals including stainless steel, mild steel, and aerospace alloys
• 36 plus grit rating balances aggressive stock removal with controlled cut quality

Compatibility

Designed for use on stainless steel, mild steel, aerospace alloys, autobody and marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners on compatible angle grinders and cut-off tools accepting 4.5-inch diameter wheels.

Installation Notes

Installation and use of abrasive cut-off wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Verify the tool's maximum RPM rating meets or exceeds the wheel's rated speed before mounting. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Always use the appropriate guard and personal protective equipment, including eye protection and gloves, during operation.
