3M 7100097932 Flap Wheel 8x2 Inch Aluminum Oxide Medium

Product Description

The 3M 7100097932 is a nonwoven aluminum oxide unmounted flap wheel designed for surface blending, finishing, and light deburring on metal and other hard surfaces. The wheel measures 8 inches in outside diameter by 2 inches in width, with a 3-inch center hole for mounting on compatible arbors and spindles. Rated to a maximum of 3,200 RPM, it carries a medium grade abrasive and a flap density rating of 5, delivering consistent scratch patterns and controlled material removal. This type of wheel is a standard tool for fabrication shops and maintenance operations requiring repeatable surface conditioning without excessive stock removal.

Nonwoven flap wheels in this size class are commonly used in industrial metal fabrication, weld blending, and surface preparation applications. They are well-suited for working on flat or contoured workpieces where a uniform finish is required before coating, plating, or further processing. The unmounted design requires a separate arbor or spindle fixture and is typically run on bench-mounted or pedestal grinding equipment, as well as compatible stationary finishing machines.

Key Features

• Aluminum oxide abrasive material for consistent cutting action on metal surfaces
• Nonwoven construction provides controlled flexibility and even scratch pattern
• Medium grade for general-purpose surface blending and light deburring
• 8-inch outside diameter with 3-inch center hole fits standard industrial arbors
• 3,200 maximum RPM rating for safe operation on compatible equipment
• Flap density of 5 for balanced abrasive contact across the workpiece

Compatibility

Designed for use as an unmounted flap wheel on stationary finishing equipment fitted with a compatible arbor or spindle sized to accept a 3-inch center hole.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel mounting procedures. Ensure all power to the equipment is off and locked out before mounting or removing the wheel. Verify that the spindle speed of the equipment does not exceed the 3,200 RPM maximum rating stamped on or associated with this wheel. Always inspect the wheel for damage before use and confirm the arbor and flanges are properly sized and torqued according to the equipment manufacturer guidelines and applicable ANSI B7 safety standards.
