3M 7100138161 Ceramic Flap Wheel 60 Grit 1.5 Inch

Product Description

The 3M 7100138161 is a 747D ceramic flap wheel designed for light grinding, blending, deburring, and polishing on a variety of metal surfaces. At 1.5 inches in diameter, the wheel features ceramic aluminum oxide abrasive flaps bonded to an X-weight cotton cloth backing. The abrasive flaps conform to rounded and irregular workpiece profiles, delivering a smooth, consistent finish. A resin bond system and included grind-aid additive keep the wheel running cooler on stainless steel and other metals. This wheel is built for trade and industrial use by machinists, fabricators, and metal finishing technicians.

This flap wheel is suited for metal fabrication shops, maintenance environments, and production finishing operations where consistent surface conditioning is required. It performs well on stainless steel, mild steel, aluminum, and similar metals. The conforming flap design makes it particularly effective on contoured, curved, or irregular surfaces where rigid abrasive wheels lose contact. The 60-grit ceramic abrasive provides an aggressive cut rate while the flap construction transitions smoothly to a blended finish.

Key Features

• Ceramic aluminum oxide abrasive blend for high cut rate and extended wheel life
• X-weight cotton cloth backing withstands aggressive sanding and grinding demands
• Resin bond resists thermal and chemical breakdown for durability under load
• Flap design conforms to rounded and irregular surfaces for even material removal
• Grind-aid additive reduces heat buildup on stainless steel and other metals
• Coated abrasive construction on cloth substrate for flexibility and strength

Compatibility

Designed as an OEM-style replacement flap wheel for use with compatible rotary tools, die grinders, and spindle arbors accepting 1.5-inch diameter flap wheel accessories.

Installation Notes

Installation and operation should be performed by qualified machinists or metal finishing technicians familiar with rotary abrasive tools. Confirm the tool spindle speed rating meets or does not exceed the maximum rated RPM of the wheel before mounting. Always power down and disconnect the tool from its power source before mounting or removing the wheel. Wear appropriate PPE including eye protection and gloves during operation.
