3M 7010310512 Flexible Flap Wheel 8 Inch 100 Grit

Product Description

The 3M 7010310512 is an aluminum oxide flexible flap wheel designed for grinding, deburring, and finishing operations on inside diameters and contoured surfaces. Running at 100 grit, it removes burrs, flash, and parting lines while leaving a consistent linear scratch pattern. The coated abrasive flaps flex to follow surface contours, and the steel mandrel construction reduces chatter during use. At 8 inches in diameter, this wheel suits a range of bench-mounted or portable rotary tool applications. Industrial maintenance techs, metal fabricators, and finishing professionals are the primary installers.

This flap wheel is suited for both ferrous and non-ferrous materials, making it a practical choice across fabrication shops, maintenance facilities, and production environments. It is commonly used to clean up castings, smooth weld seams, and deburr machined bores where a consistent, straight-line finish is required. The flexible flap design allows it to conform to irregular shapes and inside contours without gouging the workpiece surface.

Key Features

• Aluminum oxide abrasive cuts quickly on ferrous and non-ferrous metals
• Flexible flaps conform to contoured and irregular surfaces
• Produces a consistent linear scratch pattern for uniform finish
• Steel mandrel construction minimizes chatter and vibration
• 100 grit rating suited for deburring, flash removal, and parting line smoothing
• 8 inch diameter provides broad surface coverage on larger bores and contours

Compatibility

Designed as a standard replacement-style flexible flap wheel for rotary bench grinders and portable tools accepting an 8 inch diameter wheel with a compatible mandrel attachment.

Installation Notes

Installation and use should be performed by qualified personnel familiar with abrasive wheel safety. Always power down and lock out the tool before mounting or changing the wheel. Inspect the wheel for damage before each use and confirm the tool RPM rating meets or exceeds the wheel maximum RPM rating. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
