3M 7100138312 Ceramic Flap Wheel P120 Grit 1 Inch

Product Description

The 3M 7100138312 is a ceramic abrasive flap wheel from the 747D series, engineered for light grinding, blending, deburring, and polishing on metal surfaces. The wheel measures 1 inch in diameter and features P120 grit ceramic aluminum oxide abrasive bonded to X-weight cotton cloth backing with a resin bond system. Each flap conforms to the contours of the workpiece, producing a smooth, clean finish on rounded or irregular surfaces. A grind-aid additive is built into the abrasive coating to reduce heat buildup during use on stainless steel and other metals. This wheel weighs 0.05 pounds and is sold individually.

This flap wheel is suited for metalworking applications in fabrication shops, maintenance environments, and light manufacturing. It performs well on contoured, curved, or complex profiles where rigid abrasive wheels cannot reach effectively. Typical use cases include weld blending, edge deburring, and surface prep on stainless steel, carbon steel, aluminum, and other common metals. It is appropriate for use by machinists, fabricators, pipefitters, and maintenance technicians who require consistent finish quality on irregular geometry.

Key Features

• Ceramic aluminum oxide blend delivers high cut rate and extended abrasive life
• X-weight cotton backing withstands aggressive sanding and grinding loads
• Resin bond resists thermal and chemical breakdown for longer wheel service life
• Flap design conforms to rounded and irregular workpiece surfaces for smooth, uniform finish
• Built-in grind-aid runs cooler on stainless steel and other heat-sensitive metals
• P120 grit provides a balance of stock removal and surface finish quality

Compatibility

Designed as an OEM-style abrasive flap wheel for use on rotary tools and die grinders accepting 1-inch diameter mounted abrasive wheels across light metalworking and finishing applications.

Installation Notes

This wheel is installed and serviced by machinists, fabricators, and metalworking technicians. Confirm the spindle speed rating of the host tool does not exceed the maximum RPM rated for the wheel before mounting. Ensure the spindle is fully stopped and the tool is disconnected from power before changing abrasive wheels. Wear appropriate eye protection and gloves during installation and operation.
