3M 7100304307 Cubitrona 3 Ceramic Cut-off Wheel 4.5 in

Product Description

The 3M 7100304307 Cubitrona 3 Cut-Off Wheel is a 4.5-inch diameter, 0.04-inch thick abrasive wheel engineered for high-speed material removal on metal and alloy substrates. It uses 3M Precision Shaped Ceramic Grain, a re-engineered mineral with sharp, angular structures that continuously fracture to expose fresh cutting edges. The result is a wheel that runs cooler, wears more evenly, and maintains cut rate throughout its service life. Rated at 60-plus grit, this wheel is suited for trade professionals in fabrication, automotive, marine, and industrial maintenance who demand consistent performance across extended cutting sessions.

This cut-off wheel is designed for perpendicular cuts using the outer edge of the wheel. Typical applications include cutting stainless steel tubing, mild steel plate, exhaust pipes, autobody and marine sheet metal, clamps, and rusted fasteners. It is also rated for use on aerospace alloys, making it a practical choice for MRO and aviation support shops. The wheel ships in a minimum pack quantity of 2, which suits contractors and shop environments stocking consumables in volume. Installation requires a compatible angle grinder or cut-off tool with a 4.5-inch arbor fitment.

Key Features

• Re-Engineered Precision Shaped Ceramic Grain continuously fractures to maintain sharp cutting edges and reduce heat buildup
• Delivers up to 10% faster cut rate compared to the Cubitrona II Performance Abrasives line
• Removes up to 3 times more material per wheel compared to the Cubitrona II Performance Abrasives line
• 4.5-inch diameter with 0.04-inch thickness for perpendicular, controlled cuts with minimal kerf width
• Compatible with stainless steel, mild steel, autobody sheet metal, marine sheet metal, and aerospace alloys
• Fewer wheel changeovers per job translates to measurable productivity gains in high-volume cutting operations

Compatibility

Designed for use on stainless steel, mild steel, autobody and marine sheet metal, exhaust components, clamps, rusted fasteners, and aerospace alloys. Requires an angle grinder or cut-off tool rated for 4.5-inch diameter cut-off wheels.

Installation Notes

Installation and mounting must be performed by a qualified operator following the tool and wheel manufacturer guidelines. Always power down and disconnect the grinder from its power source before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating printed on the wheel. Use appropriate personal protective equipment including face shield, gloves, and hearing protection during operation.
