3M 7100176081 Depressed Center Grinding Wheel 4.5 in 36 Grit

Product Description

The 3M 7100176081 is a Type 27 depressed center grinding wheel built for heavy-duty stock removal, beveling, and weld grinding. Measuring 4.5 inches in diameter and 0.25 inches thick, this wheel uses 3M Precision-Shaped Grain technology to maintain a fast, consistent cut throughout its service life. The 36-grit abrasive is suited for aggressive material removal on stainless steel, mild steel, carbon steel, and aerospace alloys. Fabricators, welders, and metal finishing trades rely on this wheel for applications where long wheel life and sustained cut rate reduce downtime and changeout frequency.

This wheel is used in industrial fabrication, structural steel work, weld prep, and surface conditioning applications. It performs on both handheld angle grinders and pressure-assisted or robotic grinding setups. The Type 27 depressed center profile provides clearance for flat and edge grinding, making it well suited for tight joint access and weld seam removal across a range of metal substrates.

Compatibility

Designed for use with angle grinders and tools configured for Type 27 depressed center grinding wheels. Always verify that the tool RPM rating meets or exceeds the wheel speed rating before use.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel safety. Inspect the wheel for cracks or damage before mounting and never use a damaged wheel. Mount only on a grinder fitted with an approved guard per ANSI B7.1, and ensure the tool is powered off and unplugged before changing wheels. Do not exceed the maximum RPM marked on the wheel.
