3M 7100021078 Scotch-brite Exl Deburring Wheel 12 Inch

Product Description

The 3M 7100021078 is a Scotch-Brite EXL convolute deburring wheel engineered for high-performance surface finishing on metals, composites, and glass. Built with a hard, dense, and conformable construction, this 12-inch diameter wheel deburrs, finishes, and polishes in a single pass without undercutting, gouging, or distorting the workpiece. The convolute build keeps the wheel running true, producing a consistent finish across production runs. A unique resin system minimizes smearing, cutting down cleaning time between operations. Metalworking shops, fabrication facilities, and finishing lines rely on this wheel for both manual and robotic processing applications.

This wheel is well suited to deburring stamped parts, laser-cut components, and workpieces requiring finishing after belt sanding. Its conformable nature allows the abrasive to maintain contact with complex or irregular profiles, making it a practical choice for automated robotic setups as well as bench-mounted and floor-stand grinders. It is effective across a wide range of substrates, reducing the need to swap between multiple wheel types during a shift. Heat buildup is minimized during use, lowering the risk of discoloration or warping on heat-sensitive materials.

Key Features

• Hard, dense, conformable construction deburrs and finishes without undercutting or distorting the workpiece
• Convolute build maintains wheel balance for a consistent, repeatable surface finish
• Effective on metals, composites, and glass, consolidating multiple finishing tasks into one wheel
• Unique resin system minimizes smearing and reduces post-operation cleaning time
• Minimizes heat buildup, protecting heat-sensitive substrates from discoloration and warping
• Conformability supports robotic processing on complex-shaped parts

Compatibility

Designed for use on bench-mounted, floor-stand, or robotic grinding and finishing equipment accepting convolute wheels with a 12-inch diameter arbor configuration. Suitable for deburring and finishing metals, composites, and glass substrates.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Verify the grinder or finishing machine is fully de-energized and locked out before mounting or removing the wheel. Confirm the machine spindle speed rating meets or does not exceed the maximum rated speed marked on the wheel before operation. Inspect the wheel for damage prior to each use and never operate a cracked or damaged wheel.
