3M 7000120681 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7000120681 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. The wheel measures 3 inches in diameter with a 3/8 inch arbor and uses aluminum oxide as its abrasive mineral. Its soft, conformable construction allows the abrasive material to maintain consistent contact across irregular and complex part geometries. Machinists, fabricators, and finishing technicians use this wheel on bench grinders, die grinders, and automated robotic processing equipment where controlled surface prep is required.

This unitized wheel is suited for both manual and automated finishing applications in fabrication shops, machine shops, and light manufacturing environments. The conformable layered construction makes it effective on contoured surfaces and part edges where rigid abrasives would skip or chatter. It is appropriate for deburring cut edges, blending weld seams, and preparing surfaces prior to coating or inspection. The wheel can be dressed to restore its cutting profile, extending usable life during production runs.

Key Features

• Soft, conformable unitized construction maintains abrasive contact on complex and contoured part shapes
• Can be dressed at the wheel edge for consistent deburring, finishing, and polishing performance
• Operates in both clockwise and counterclockwise directions for flexible setup
• Minimizes heat buildup to reduce thermal impact on heat-sensitive base materials
• Resists smearing for cleaner cut surfaces and reduced post-process prep time
• Aluminum oxide abrasive mineral suitable for ferrous and non-ferrous metal alloys as well as many plastics and composites

Compatibility

Designed as an OEM-style replacement unitized abrasive wheel for use on bench grinders, die grinders, and robotic finishing spindles accepting a 3/8 inch arbor.

Installation Notes

Installation and mounting should be performed by a qualified machinist or abrasives technician following the grinder or spindle manufacturer's arbor-mounting procedure. Power down and lock out the machine before mounting or removing the wheel. Verify that the machine's rated RPM does not exceed the wheel's maximum operating speed before use. Always inspect the wheel for damage prior to each use and do not use a damaged or out-of-round wheel.
