3M 7000028453 Scotch-brite Exl Unitized Wheel 3 in Ao

Product Description

The 3M 7000028453 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 3 inches in diameter with a 3/8 inch arbor bore and uses aluminum oxide (AO) as the abrasive mineral. Its soft, conformable construction allows the abrasive material to maintain consistent contact across complex part geometries. Machinists, fabricators, and finishing technicians install this wheel on bench grinders, die grinders, or automated robotic tooling for controlled, repeatable results on production and repair operations.

This unitized wheel is suited for edge deburring, light stock removal, and final finishing passes on ferrous and non-ferrous metals as well as many engineering plastics and composite materials. The layered, bonded construction supports both clockwise and counterclockwise rotation, making it adaptable to a range of machine setups. It is commonly used in metal fabrication shops, aerospace component finishing, and general manufacturing environments where surface quality and heat management are priorities.

Key Features

• Conformable unitized construction keeps abrasive in contact with complex or contoured part surfaces
• Supports clockwise and counterclockwise rotation for versatile machine compatibility
• Resists smearing on workpiece surfaces, reducing prep time between passes
• Minimizes heat buildup during operation, protecting heat-sensitive base materials
• Wheel edge can be dressed to maintain cutting geometry for deburring, finishing, and polishing
• Aluminum oxide abrasive mineral delivers consistent cut on metal alloys, plastics, and composites

Compatibility

Designed as a unitized abrasive wheel for use on bench grinders, die grinders, and robotic finishing equipment accepting a 3/8 inch arbor and accommodating a 3 inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the equipment manufacturer's speed and arbor specifications. Confirm the machine spindle RPM rating does not exceed the maximum rated speed of the wheel before mounting. Power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for damage before each use and do not operate a cracked or deformed wheel.
