3M 7100076955 Scotch-brite Exl Unitized Abrasive Wheel

Product Description

The 3M 7100076955 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. It measures 0.5 inches in diameter and mounts on a 0.125 inch arbor. The wheel is built with a soft, conformable, layered construction that keeps the abrasive media in contact with the workpiece surface throughout the cut. Aluminum oxide (AO) abrasive provides consistent material removal while minimizing heat buildup, making it a practical choice for heat-sensitive substrates. Machinists, metal fabricators, and production finishing technicians reach for this style of wheel for both manual and automated applications.

This unitized wheel fits standard rotary tools, die grinders, and bench-mounted mandrel setups used in metal fabrication shops and light manufacturing environments. The conformable structure makes it well-suited for deburring complex-shaped or contoured parts, including robotic and automated finishing lines. It performs on ferrous and non-ferrous alloys, as well as many engineering plastics and composite materials. The wheel can be rotated in either clockwise or counterclockwise directions, adding flexibility in multi-axis tooling setups.

Key Features

• Soft, layered unitized construction conforms to complex part geometries for consistent contact
• Operates in clockwise or counterclockwise rotation for flexible tooling configurations
• Aluminum oxide abrasive resists smearing for cleaner finished surfaces and reduced prep time
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive materials
• Wheel edge can be dressed for precision deburring, finishing, and polishing work
• Suitable for metal alloys, plastics, and composites in both manual and robotic processing

Compatibility

Designed as an OEM-style replacement and standard fitment for rotary tools and die grinders accepting a 0.125 inch arbor, used in metal fabrication, finishing, and light manufacturing applications.

Installation Notes

Install on a compatible mandrel sized for a 0.125 inch arbor and confirm the tool RPM rating does not exceed the wheel's rated speed before operation. Power down and disconnect the tool from its power source before mounting or removing the wheel. Inspect the wheel for damage before each use and discard any wheel showing cracks, chips, or uneven wear. Eye protection and appropriate PPE should be worn per shop safety standards during all grinding and finishing operations.
