3M 7010331220 Flexible Flap Wheel 8 Inch 60 Grit Ao

Product Description

The 3M 7010331220 is an aluminum oxide flexible flap wheel designed for deburring, edge finishing, and surface blending on inside diameters and contoured workpieces. The flexible coated abrasive flaps conform to irregular surfaces and produce a consistent linear scratch pattern. At 8 inches in diameter with a 60-grit cut, this wheel handles both ferrous and non-ferrous materials efficiently. A steel mandrel minimizes chatter during operation, supporting stable, controlled stock removal. Metal fabricators, machinists, and tool-and-die professionals are the primary users of this wheel type.

This flap wheel is suited for grinding, deburring, and finishing operations on inside diameters, contours, and complex part geometries. Typical applications include removing flash from castings, smoothing parting lines, and cleaning up burrs on machined components. The aluminum oxide abrasive cuts aggressively across a broad range of base materials, making this wheel a general-purpose choice for job shop and production environments alike.

Key Features

• Flexible flaps conform to flat and contoured surfaces for consistent contact
• Aluminum oxide abrasive cuts quickly on ferrous and non-ferrous materials
• Produces a linear scratch pattern suited to finish grinding and blending
• Steel mandrel reduces chatter for stable, controlled operation
• 60-grit cut balances stock removal speed with surface finish quality
• 8-inch diameter provides broad coverage on larger inside diameters and profiles

Compatibility

Designed as a general-purpose flexible flap wheel for use on bench grinders, pedestal grinders, or compatible arbor-driven equipment that accepts 8-inch mounted abrasive wheels.

Installation Notes

Installation and operation should be performed by a qualified machinist or metalworking professional. Always power down and lock out the grinder before mounting or removing the wheel. Verify that the spindle speed rating of the equipment does not exceed the maximum RPM rating marked on the wheel. Inspect the wheel for damage before each use and never operate a cracked or compromised abrasive wheel.
