3M 7100078404 Unitized Quick Change Abrasive Wheel 2 Inch

Product Description

The 3M 7100078404 is a unitized, non-woven aluminum oxide quick change abrasive wheel designed for medium-pressure surface preparation on flat and contoured workpieces. Part of the Standard Abrasives Quick Change 600 Series, it carries a soft-to-medium density construction that blends surfaces, removes light burrs, and radii edges without aggressive stock removal. The TR threaded hub allows fast disc attachment and grade swaps directly on compatible rotary tools, reducing downtime between tasks. At 2 inches in diameter, it is suited for detail work and confined areas where larger wheels cannot reach. Fabricators, machinists, and maintenance technicians working with both ferrous and non-ferrous metals are the primary users of this wheel.

This wheel is used in light deburring, surface blending, and edge radiusing applications across metal fabrication, aerospace prep work, and general maintenance environments. The open non-woven web resists loading, making it effective on aluminum and other gummy non-ferrous metals where conventional abrasives tend to clog. It is rated for use on flat stock, tubing, and contoured parts where consistent finish quality is required. The 600 Series offers increased edge durability compared to the 500 Series, extending service life in repetitive blending and cleaning passes.

Key Features

Compatibility

Designed for use with TR-style quick change tool holders compatible with 2-inch unitized wheels. No specific model compatibility data was provided in the product input.

Installation Notes

This wheel is installed by machinists, fabricators, and maintenance technicians using TR-style right-angle grinders or die grinders. Ensure the tool is powered off and disconnected from the air or electrical supply before mounting or swapping wheels. Thread the TR hub fully into the tool spindle and verify it is secure before operation. Always wear appropriate eye and face protection and observe the maximum RPM rating of the tool relative to the wheel.
