3M 7000120912 Scotch-brite Exl Deburring Wheel 8 Inch

Product Description

The 3M 7000120912 is a convolute deburring and finishing wheel from the Scotch-Brite EXL line, designed for rapid deburring, surface finishing, and polishing of metals, composites, and glass. Built with a hard, dense construction, the wheel removes burrs and sharp edges without undercutting, gouging, or distorting the workpiece. The convolute build keeps the wheel running smoothly under load, delivering a consistent surface finish across production runs. It measures 8.7 inches in diameter, 4.21 inches wide, and weighs 1.13 pounds. Fabricators, tool-and-die shops, and production finishing operations are the primary users of this wheel type.

This wheel is suited for deburring stamped parts, laser-cut components, and parts requiring finishing after belt sanding. Its conformable nature keeps the abrasive material in contact with complex or irregular part geometries, making it a reliable choice for both manual bench grinding applications and robotic or automated finishing cells. It handles a wide range of substrates, including steel, aluminum, composites, and glass, reducing the need to change wheels between material types.

Key Features

• Hard, dense, conformable construction deburrs and finishes without undercutting or distorting the workpiece
• Convolute wheel design runs smoothly under load and produces a consistent surface finish
• Effective on metals, composites, and glass for multi-material finishing with one wheel
• Unique resin system minimizes smearing, reducing post-process surface cleaning time
• Minimizes heat buildup, reducing risk of discoloration or warping on heat-sensitive substrates
• Conformable abrasive structure maintains contact on complex-shaped parts in robotic processing environments

Compatibility

Designed as an OEM-style convolute deburring wheel for use on standard bench grinders, pedestal grinders, and automated finishing equipment accepting 8-inch diameter wheel arbors.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel safety and applicable ANSI B11 or OSHA 1910.215 standards for abrasive wheel machinery. Power down and lock out the grinder before mounting or removing any wheel. Inspect the wheel for cracks or damage before each use and verify that the machine speed rating does not exceed the maximum rated RPM of the wheel. Always use the appropriate flanges and guards as specified by the equipment manufacturer.
