3M 7100313202 Cubitrona 3 Grinding Wheel 9 in

Product Description

The 3M 7100313202 Cubitrona 3 is a depressed center grinding wheel built for heavy weld removal and aggressive material removal on a wide range of metals. It uses 3M Re-Engineered Precision-Shaped Grain, a ceramic abrasive technology with sharp, angular structures that fracture continuously to expose fresh cutting edges. This self-sharpening action helps the wheel run cooler, wear evenly, and maintain cut rate throughout the wheel's life. The result is a rigid bonded wheel that delivers fast stock removal with reduced operator pressure. Licensed metalworkers, fabricators, and maintenance welders are the primary installers and users of this product.

This grinding wheel is intended for heavy-duty applications in metal fabrication, structural steel work, and aerospace component finishing. It is specially formulated for use on stainless steel, mild steel, and aerospace alloys, though it performs well on nearly all weldable metals. Typical use cases include weld bead removal, surface conditioning, and edge preparation on flat and curved workpieces. The depressed center profile allows the wheel to sit at the correct angle on a right-angle grinder, providing full face contact during aggressive stock removal passes.

Key Features

• Re-Engineered Precision-Shaped Grain continuously fractures to maintain sharp cutting edges and run cool
• Delivers up to 15% increased cut rate compared to Cubitrona II Performance Abrasives
• Removes up to 1.5x more material compared to Cubitrona II Performance Abrasives
• Specially formulated for stainless steel, mild steel, and aerospace alloys
• Rigid bond construction supports heavy weld removal and high-pressure grinding applications
• Depressed center design provides proper grinding angle on standard right-angle grinders

Compatibility

Designed for use on stainless steel, mild steel, and aerospace alloys; compatible with standard right-angle grinders accepting 9-inch depressed center grinding wheels.

Installation Notes

Mounting and use of grinding wheels should be performed by trained personnel following ANSI B7.1 safety standards and the grinder manufacturer's guidelines. Inspect the wheel for cracks or chips before every mount and never exceed the maximum RPM marked on the wheel. Ensure the grinder is fully powered off and unplugged before changing wheels. Always use the appropriate guard and personal protective equipment including eye and face protection when operating.
