3M 7000120777 Scotch-brite Exl Convolute Deburring Wheel

Product Description

The 3M 7000120777 is a Scotch-Brite EXL convolute deburring wheel designed for high-production deburring, finishing, and polishing of metals, composites, and glass. Built with a hard, dense, conformable construction, it removes burrs and blends surfaces without undercutting, gouging, or distorting the workpiece. The aluminum oxide abrasive mineral and convolute build deliver consistent, repeatable results across cycles. This wheel is used in shop fabrication, robotic processing cells, and bench finishing operations by machinists, fabricators, and metalworking professionals who need a reliable surface-prep tool that handles multiple tasks without wheel changeovers.

This deburring wheel suits a wide range of metalworking applications including finishing stamped parts, laser-cut components, and surfaces coming off belt sanders. Its conformable nature allows the abrasive to maintain contact with complex geometries, making it a practical choice for both manual bench work and automated robotic finishing systems. It performs on steel, aluminum, titanium, composites, and glass substrates wherever a clean, smooth, burr-free surface is required before assembly, coating, or inspection.

Key Features

• Hard, dense convolute construction runs smooth and produces a consistent finish across the wheel life
• Conformable structure keeps abrasive in contact with complex or irregular part geometries during robotic or manual processing
• Effective on all metal types, composites, and glass — reduces need for multiple wheel changes
• Unique resin system minimizes smearing and cuts cleaning time between operations
• Minimizes heat buildup to reduce risk of discoloration or warping on heat-sensitive substrates
• Suitable for deburring stamped or laser-cut parts and for blending after belt sanding

Compatibility

Designed for use on metals including steel, aluminum, and titanium, as well as composites and glass. Compatible with standard arbor-mounted wheel setups used in bench grinders and robotic finishing systems where convolute wheel profiles are specified.

Installation Notes

Mounting and operation of abrasive deburring wheels should be performed by qualified shop personnel following the wheel manufacturer's rated speed and arbor specifications. Always power down and de-energize the grinder or finishing unit before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and never exceed the maximum RPM rating marked on the wheel. Eye protection and appropriate PPE are required during operation per ANSI B11 and shop safety standards.
