3M 7010328770 Flap Wheel 6x1 in Aluminum Oxide Medium

Product Description

The 3M 7010328770 is a nonwoven aluminum oxide unmounted flap wheel designed for surface conditioning, blending, and finishing applications in metalworking and fabrication environments. Measuring 6 inches in outside diameter and 1 inch wide with a 2-inch center hole, it mounts to compatible arbors and spindles used with bench grinders, lathes, or pedestal-mounted equipment. Rated to a maximum of 4,000 RPM, this medium-grade wheel delivers consistent cut and finish on ferrous and nonferrous metals. It is installed and operated by machinists, tool-and-die workers, fabricators, and maintenance technicians who require reliable surface preparation performance.

This flap wheel is suited for intermediate stock removal and surface blending on flat, contoured, and irregular workpiece profiles. The nonwoven construction with medium-grade aluminum oxide abrasive conforms to part geometry, making it a practical choice for deburring edges, removing weld scale, and producing a uniform scratch pattern before finishing. It is used in job shops, maintenance facilities, and light industrial production settings where consistent results are expected across repeated cycles.

Key Features

• Nonwoven aluminum oxide abrasive construction for consistent surface conditioning
• Medium grade abrasive for material removal and surface blending in one step
• 6-inch outside diameter with 1-inch width and 2-inch center hole for arbor mounting
• 4,000 RPM maximum rated speed for safe operation on standard equipment
• Flap density of 7 provides controlled cut and finish consistency
• No interleaf construction allows direct abrasive contact with the workpiece

Compatibility

Designed as an unmounted flap wheel for use with arbors and spindles accepting a 2-inch center hole bore, compatible with bench grinders, lathes, and pedestal grinder setups rated at or below 4,000 RPM.

Installation Notes

Installation should be performed by qualified personnel following all applicable machine guarding and abrasive wheel safety requirements. Ensure all power is disconnected and the machine is at a full stop before mounting or removing the wheel. Verify that the spindle speed of the host machine does not exceed the 4,000 RPM rating marked on the wheel. Inspect the wheel for damage before each use and never operate a wheel that shows signs of cracking, fraying, or delamination.
