3M 7100166542 Ceramic Flap Wheel 8 Inch 60 Grit

Product Description

The 3M 7100166542 is a ceramic abrasive flap wheel designed for light grinding, blending, deburring, and polishing on a variety of metal surfaces. The wheel features ceramic aluminum oxide abrasive flaps bonded to an X-weight polyester and cotton backing. At 8 inches in diameter and 60 grit, it delivers a consistent cut rate suited for finishing work on rounded, contoured, or irregular workpiece geometry. Resin bonding resists thermal and chemical breakdown, extending wheel life under sustained use. This wheel is sold as a single unit and is a standard choice for metalworking shops and fabrication environments.

This flap wheel is used in light to moderate metalworking applications including weld blending, surface conditioning, and deburring on structural steel, stainless steel, and other metals. The abrasive flap design allows the wheel to conform to curved and irregular surfaces, making it well suited for tube, pipe, and contoured part finishing. It is commonly mounted on a bench grinder or angle grinder by machinists, fabricators, and maintenance technicians in both shop and field settings.

Key Features

• Ceramic aluminum oxide abrasive blend for high cut rate and extended wheel life
• X-weight polyester and cotton backing withstands aggressive sanding and grinding loads
• Resin bond system resists thermal and chemical deterioration during use
• Flap construction conforms to rounded and irregular surfaces for smooth, consistent results
• Flaps wear progressively to expose fresh abrasive, maintaining a fast and even cut throughout wheel life

Compatibility

Designed as a replacement or standard-stock flap wheel for bench grinders and angle grinders accepting 8-inch diameter abrasive wheels used in metal fabrication and maintenance applications.

Installation Notes

Installation and operation should be performed by qualified machinists or fabricators familiar with abrasive wheel safety. Before mounting, confirm the grinder spindle speed rating meets or exceeds the maximum RPM rating of the wheel and that the arbor size matches. Power down and lock out the grinder before changing wheels. Inspect the wheel for damage before each use and never exceed the rated operating speed.
