3M 7000028451 Scotch-brite Exl Unitized Wheel 6 in

Product Description

The 3M 7000028451 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across irregular and complex part geometries. The aluminum oxide abrasive mineral delivers reliable cut while the unitized, layered structure resists smearing and minimizes heat build-up — an important characteristic when working with heat-sensitive base materials. The wheel measures 6 inches in diameter with a 1/2 inch arbor and weighs 0.34 pounds. Licensed trade professionals and machine operators in fabrication and finishing shops are the primary users of this product.

This wheel is suited for bench-mounted finishing applications in metal fabrication, aerospace component finishing, and precision parts manufacturing. It handles deburring and surface conditioning on ferrous and non-ferrous metals as well as many plastics and composites. The conformable consistency makes it effective in robotic processing environments where consistent abrasive-to-part contact is required on contoured surfaces. The wheel can operate in both clockwise and counterclockwise directions, supporting flexible integration into existing finishing setups.

Key Features

• Conformable, layered unitized construction maintains abrasive contact on complex and contoured part geometries
• Aluminum oxide abrasive smooths, deburrs, and finishes metal alloys, plastics, and composites
• Operates in both clockwise and counterclockwise directions for flexible machine integration
• Minimizes heat build-up, reducing risk of thermal damage to heat-sensitive materials
• Resists smearing for cleaner finished surfaces and reduced prep time
• Available density range from soft and conformable to hard and aggressive to match application requirements

Compatibility

Designed for use on metal alloys, many plastics, and composites in bench-mounted or automated finishing applications requiring deburring, smoothing, or surface conditioning.

Installation Notes

Mounting and replacement of abrasive wheels should be performed by qualified personnel following the wheel manufacturer's safety guidelines and applicable ANSI B7.1 standards. Power down and de-energize the spindle completely before changing the wheel. Verify that the machine spindle speed does not exceed the maximum RPM rating marked on the wheel. Inspect the wheel for damage before mounting and ensure the arbor size matches the machine spindle.
