3M 7010331221 Flexible Flap Wheel 8 Inch 60 Grit Ao

Product Description

The 3M 7010331221 is an aluminum oxide flexible flap wheel designed for deburring, edge finishing, and surface blending on inside diameters and contoured workpieces. The coated abrasive flaps flex to follow curved and irregular surfaces, producing a consistent linear scratch pattern rather than random swirl marks. A steel mandrel reduces chatter during operation, contributing to a more controlled cut. Aluminum oxide abrasive cuts aggressively across both ferrous and non-ferrous base materials. At 60 grit, this wheel is suited for stock removal, flash removal, and smoothing parting lines before finer finishing steps. Each wheel measures 8 inches in diameter and weighs approximately 8.1 pounds.

This flap wheel is used in fabrication, metalworking, and finishing operations where internal diameters, bores, or contoured profiles require consistent surface preparation. Typical applications include deburring drilled or bored holes, smoothing cast or forged parting lines, and removing flash from machined components. The flexible flap construction allows the wheel to conform to workpiece geometry, making it practical for both flat and curved surface work. Suitable for use in production and job-shop environments handling a range of ferrous and non-ferrous parts.

Key Features

• Flexible abrasive flaps conform to flat and contoured surfaces for consistent coverage
• Produces a straight linear scratch pattern, reducing random swirl marks
• Steel mandrel reduces chatter and improves control during use
• Aluminum oxide abrasive cuts quickly on both ferrous and non-ferrous materials
• 60 grit provides effective stock removal, deburring, and parting line smoothing
• 8 inch diameter suits larger inside diameter and contour finishing applications

Compatibility

Designed as an OEM-style abrasive flap wheel suitable for use on standard grinding and finishing machinery that accepts flexible flap wheel tooling of 8 inch diameter.

Installation Notes

Installation and operation of abrasive flap wheels should be performed by qualified personnel following applicable ANSI B11 and OSHA abrasive wheel safety standards. Always power down and de-energize the grinder or finishing machine before mounting or changing the wheel. Inspect the wheel for damage before each use and confirm the machine spindle speed does not exceed the rated RPM of the wheel. Never exceed the published operating speed, and ensure all guards are in place before resuming operation.
