3M 7100313193 Depressed Center Grinding Wheel 6 in

Product Description

The 3M 7100313193 is a depressed center grinding wheel built for heavy weld removal and other demanding grinding tasks in fabrication and metalworking environments. Constructed with 3M re-engineered precision-shaped ceramic grain, the wheel features sharp, angular grain structures that continuously fracture to expose fresh cutting edges. This design allows the wheel to run cool, wear evenly, and cut fast without requiring excessive operator pressure. The result is a rigid bonded abrasive wheel that delivers consistent material removal rates across extended service cycles. Licensed tradespeople and fabricators working in industrial, commercial, and aerospace settings are the primary installers and users of this product.

This grinding wheel is suited for use on stainless steel, mild steel, and aerospace alloys, as well as most other weldable metals encountered in heavy fabrication, structural steel work, and aerospace component finishing. It is designed for depressed center angle grinders used in shop and field applications where weld seam removal, surface prep, and edge blending are routine tasks. The minimum order quantity is 2 units per box, making it appropriate for shop stocking or job lot purchasing.

Key Features

• Re-engineered precision-shaped ceramic grain continuously fractures to maintain sharp cutting edges and even wear
• Delivers up to 15% increased cut rate compared to the Cubitrona II Performance Abrasives line
• Removes up to 1.5 times more material compared to Cubitrona II Performance Abrasives, reducing changeover frequency
• Specially formulated for stainless steel, mild steel, and aerospace alloys
• Rigid bond construction supports heavy weld removal and high-pressure grinding applications
• Runs cool under load, reducing heat-related workpiece distortion risk

Compatibility

Designed for use with depressed center angle grinders accepting 6 inch diameter grinding wheels with a 1/4 inch thickness profile. Suitable for grinding stainless steel, mild steel, and aerospace alloys.

Installation Notes

Mounting and use of grinding wheels should be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Inspect the wheel for cracks or damage before mounting and never use a damaged wheel. Ensure the grinder guard is in place and that the tool RPM rating meets or exceeds the wheel's maximum rated speed before operation. Always wear appropriate PPE including face shield, gloves, and hearing protection when grinding.
