3M 7100141077 Depressed Center Grinding Wheel 4 Inch

Product Description

The 3M 7100141077 is a Type 27 depressed center grinding wheel engineered for heavy-duty metal removal on stainless steel, mild steel, carbon steel, and aerospace alloys. At 4 inches in diameter, it uses 3M Precision-Shaped Grain ceramic abrasive technology to deliver a fast, consistent cut rate during grinding, beveling, and weld removal operations. The grain structure is engineered to fracture predictably, maintaining a sharp cutting edge longer than conventional abrasive wheels. This extends wheel life and reduces the frequency of changeouts, which is especially valuable in robotic and pressure-assisted grinding applications. Weighing 0.34 pounds, it is well suited for sustained use on angle grinders in fabrication and maintenance environments.

This wheel is intended for use in metalworking applications where aggressive stock removal and long consumable life are priorities. Typical use cases include weld bead removal, surface grinding, and edge beveling on structural steel and stainless steel fabrications. The depressed center Type 27 profile allows flush and off-angle grinding in tight weld joints and flat surfaces. It is appropriate for both shop fabrication and field maintenance work across industrial, manufacturing, and aerospace settings.

Key Features

• Type 27 depressed center profile for flush and angled grinding applications
• Precision-Shaped Ceramic Grain for fast, consistent stock removal and extended wheel life
• Suitable for stainless steel, mild steel, carbon steel, and aerospace alloys
• Reduced changeout frequency benefits robotic and pressure-assisted grinding setups
• Lightweight at 0.34 pounds for sustained operator use
• Complies with ANSI B7.1 safety requirements when used with an approved tool guard

Compatibility

Designed for use with angle grinders and power tools fitted with guards approved for depressed center Type 27 grinding wheels, as specified under ANSI B7.1.

Installation Notes

Mounting and wheel changes should be performed by qualified personnel following the tool manufacturer instructions and ANSI B7.1 guidelines. Always power down and disconnect the grinder before mounting or removing the wheel. Confirm the tool spindle speed rating meets or exceeds the wheel maximum RPM rating before operation. Never operate this wheel without an approved guard in place.
