3M 7000028470 Scotch-brite Roloc 3 Inch Unitized Wheel

Product Description

The 3M 7000028470 is a Scotch-Brite Roloc EXL Unitized Wheel designed for edge deburring and surface finishing on metal workpieces. Built with a compressed, open-web construction and uniform aluminum oxide grain distribution, the wheel delivers consistent cutting action throughout its service life. At 3 inches in diameter, it mounts quickly via the Roloc twist-on attachment system, making it well-suited for multi-step finishing operations where fast disc changes reduce downtime. Machinists, fabricators, and metalworking technicians use this wheel where close dimensional tolerances must be maintained after deburring.

This unitized wheel is used in general metalworking applications including deburring machined parts, blending weld seams, and finishing flat, contoured, or irregular surfaces. The coarse grit rating makes it effective for aggressive material removal and edge cleanup on ferrous and non-ferrous metals. It is sized for use with standard right-angle die grinders and inline tools that accept 3-inch Roloc-compatible mandrels. Hard density formulations provide firm edge retention for consistent shape, while softer density variants offer conformability for complex surface profiles.

Key Features

• Unitized construction maintains consistent shape and cutting action as the wheel wears
• Aluminum oxide abrasive provides reliable performance on ferrous and non-ferrous metals
• Hard density option delivers good edge retention for repeatable deburring results
• Compressed open-web design and uniform grain distribution ensure steady cut rate
• Roloc twist-on attachment system allows fast, tool-free disc changes during multi-step finishing
• 3-inch diameter fits standard die grinders and inline tools with Roloc mandrels

Compatibility

Designed for use with power tools equipped with a 3M Roloc-compatible mandrel or holder accepting 3-inch unitized wheels.

Installation Notes

This wheel is installed and replaced by machinists or metalworking technicians using a compatible Roloc mandrel. Ensure the power tool is fully de-energized and disconnected from its power source before changing the wheel. Inspect the mandrel for wear before mounting the wheel, and verify the tool RPM rating does not exceed the maximum rated speed of the abrasive. Eye protection and appropriate PPE are required during operation per applicable shop safety standards.
