3M 7100099612 Scotch-brite Exl Unitized Wheel 3 in Fine Grit

Product Description

The 3M 7100099612 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. Built with a soft, conformable construction, the wheel maintains consistent abrasive contact across irregular and complex part geometries. At 3 inches in diameter and finished with a fine-grit silicon carbide abrasive, this wheel suits precision surface finishing where heat control and clean results matter. It weighs approximately 0.03 pounds and is sold as an individual unit. Fabricators, machinists, and finishing technicians reach for this wheel when edge quality and surface prep consistency are critical to downstream processes.

This unitized wheel is used in both manual and automated finishing applications, including robotic processing setups where consistent abrasive conformability is required. Its fine-grit silicon carbide composition makes it well suited for light deburring, edge blending, and surface refinement on ferrous and non-ferrous metals as well as many plastics and composites. It performs in both clockwise and counterclockwise rotation directions, supporting flexible fixture and tooling configurations on bench grinders, right-angle grinders, and automated finishing cells.

Key Features

• Soft, conformable unitized construction keeps abrasive in consistent contact with complex or irregular part shapes
• Fine-grit silicon carbide abrasive delivers controlled material removal for deburring and surface finishing
• Operates in both clockwise and counterclockwise directions for flexible tooling setups
• Minimizes heat buildup, reducing thermal impact on heat-sensitive materials and substrates
• Resists smearing for cleaner finished surfaces and reduced prep between operations
• Wheel edge can be dressed to maintain cutting efficiency over the service life of the wheel

Compatibility

Designed as an OEM-style replacement or direct-use unitized finishing wheel for bench grinders, angle grinders, and automated finishing equipment accepting 3-inch diameter unitized wheels.

Installation Notes

Installation and mounting should be performed by a qualified machinist or finishing technician following the tool manufacturer's instructions. Ensure the spindle speed of the grinder or finishing tool does not exceed the maximum rated RPM printed on the wheel or its packaging. Power down and de-energize all equipment before mounting or removing the wheel. Inspect the wheel for damage before each use and discard any wheel showing cracks, tears, or delamination.
