3M 7100305149 Cut and Grind Wheel 4.5 in 36 Grit

Product Description

The 3M 7100305149 is a Cubitrona 3 Cut and Grind Wheel built for aggressive cutting and grinding on both stainless steel and mild steel. The wheel uses 3M Re-Engineered Precision Shaped Ceramic Grain, a proprietary technology where sharp, angular grain structures continuously fracture to form new cutting points. This mechanism allows the wheel to run cooler, wear evenly, and maintain cutting speed throughout the life of the disc. At 4.5 inches in diameter and 0.125 inches thick with a 36-plus grit rating, it is engineered for trades that need a single wheel to handle multiple tasks without a tool change.

This wheel is suited for metal fabrication, maintenance, and field service work where both cutting and grinding tasks occur in the same job. It fits standard 4.5 inch angle grinders commonly used by ironworkers, pipefitters, welders, and general contractors. The dual-function design allows it to serve as both a cut-off wheel and a grinding wheel on stainless and mild steel substrates, reducing the need to swap discs mid-job. It is particularly effective for cutting, grinding, and gouging operations where speed and finish quality both matter.

Key Features

• Dual-function design works as both a cut-off wheel and a grinding wheel on a single tool
• Re-Engineered Precision Shaped Ceramic Grain continuously fractures to expose sharp cutting points, extending wheel life and reducing heat buildup
• Rigid, reinforced, resin-bonded construction rated for stainless steel and mild steel
• Reformulated wheel composition delivers improved balance and smoother action compared to prior Cubitrona II abrasives
• 36-plus grit rating for aggressive material removal with controlled surface finish
• 4.5 inch diameter fits standard angle grinders common across metal trades

Compatibility

Designed for use on stainless steel and mild steel substrates with standard 4.5 inch angle grinders. Compatible with cutting, grinding, and gouging applications in both shop and field environments.

Installation Notes

Mounting and replacement of abrasive wheels should be performed by a qualified operator following the grinder manufacturer's instructions and applicable ANSI B11 or OSHA 1910.215 safety standards. Always power down and disconnect the tool before changing wheels. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating marked on the wheel. Eye protection, gloves, and appropriate face shielding are required during operation.
