3M 7100304007 Cubitrona 3 Cut-off Wheel 5 in 36 Grit

Product Description

The 3M 7100304007 Cubitrona 3 Cut-Off Wheel is a 5-inch diameter, 0.045-inch-thick abrasive wheel built for high-speed metal cutting in demanding trade and industrial environments. It uses 3M Re-Engineered Precision Shaped Ceramic Grain, a proprietary technology that forms sharp, angular structures designed to fracture continuously, maintaining sharp cutting edges throughout the wheel's life. The result is faster material removal, reduced operator pressure, and longer wheel life compared to previous-generation abrasive wheels. Licensed tradespeople and fabricators use this wheel where productivity and consistent cut quality on hard metals matter most.

This cut-off wheel is suited for cutting stainless steel, mild steel, aerospace alloys, autobody and marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners. It is designed for use with angle grinders in fabrication shops, field service, shipyards, automotive repair, and aerospace maintenance environments. The wheel performs perpendicular cuts using the outer edge, making it a direct fit for standard metal-cutting tasks across a broad range of ferrous and non-ferrous materials.

Key Features

• 5-inch diameter, 0.045-inch-thick profile optimized for fast perpendicular cuts on metal
• Re-Engineered Precision Shaped Ceramic Grain continuously fractures to expose fresh cutting edges, reducing heat buildup
• Up to 10% faster cut rate compared to Cubitrona II Performance Abrasives
• Removes up to 3x more material per wheel compared to Cubitrona II Performance Abrasives
• 36 Plus grit rating balances aggressive stock removal with controlled cutting action
• Compatible with stainless steel, mild steel, aerospace alloys, and sheet metal applications

Compatibility

Designed for use on stainless steel, mild steel, aerospace alloys, autobody sheet metal, marine sheet metal, stainless steel tubing, exhaust pipes, clamps, and rusted fasteners using standard 5-inch angle grinder configurations.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following all applicable ANSI B7.1 safety standards for abrasive wheel use. Always power down and disconnect the grinder from its power source before mounting or removing a cut-off wheel. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating marked on the wheel. Wear appropriate PPE including eye and face protection, gloves, and hearing protection during operation.
