3M 7010331218 Flexible Flap Wheel 6 Inch 100 Grit Ao

Product Description

The 3M 7010331218 is an aluminum oxide flexible flap wheel designed for grinding, deburring, and finishing work on inside diameters and contoured surfaces. The flexible coated abrasive flaps conform to irregular profiles and produce a consistent linear scratch pattern, making this wheel a practical choice for smoothing parting lines, removing flash, and cleaning up edges. At 6 inches in diameter and 100 grit, it cuts quickly on both ferrous and non-ferrous materials. A steel mandrel construction reduces chatter during operation, improving surface consistency and control.

This flap wheel is suited for metalworking applications in fabrication shops, maintenance environments, and production finishing lines. It is designed to work on inside diameters and contoured workpieces where flat grinding wheels cannot reach. Typical uses include deburring cast or machined parts, blending weld seams on tubular sections, and smoothing flash on formed metal components. Its flexible design helps maintain consistent abrasive contact across uneven or curved surfaces.

Key Features

• Flexible flaps conform to flat and contoured surfaces for uniform finishing
• Aluminum oxide abrasive cuts quickly on ferrous and non-ferrous metals
• Produces a linear scratch pattern suitable for consistent surface finish
• Steel mandrel reduces chatter and improves control during use
• Coated abrasive flaps effective for deburring inner diameters and contours
• 100 grit provides a balance of material removal and surface refinement

Compatibility

Designed as a standard replacement-style flexible flap wheel for use with compatible mandrel-mount grinding equipment rated for the wheel diameter and speed.

Installation Notes

This wheel is installed by metalworking or fabrication professionals using compatible rotary tools or die grinders. Always verify that the tool spindle speed does not exceed the maximum rated RPM marked on the wheel before mounting. Inspect the wheel for damage before each use and discard any wheel that shows signs of cracking or delamination. Wear appropriate PPE including eye protection and gloves when operating abrasive wheels.
