3M 7100126839 Scotch-brite Exl Deburring Wheel 8 Inch Fine

Product Description

The 3M 7100126839 is a convolute deburring and finishing wheel from the Scotch-Brite EXL line, designed for use on metals, composites, and glass. The hard, dense construction removes burrs quickly while conforming to complex part geometries, leaving a smooth, clean surface without undercutting, gouging, or distorting the workpiece. At 8 inches in diameter and a fine grit rating, this wheel suits both manual and robotic finishing operations. A unique resin system minimizes smearing and heat buildup, reducing the risk of discoloration or warping on heat-sensitive substrates.

This wheel is suited for deburring stamped or laser-cut parts and for finishing work after belt sanding. Its convolute construction keeps the wheel running smooth and delivers a consistent finish across production runs. The conformable design allows the abrasive to maintain contact with irregular and complex-shaped surfaces, making it effective in automated robotic processing as well as manual bench operations. Metal fabricators, composites finishers, and industrial maintenance technicians are the primary users of this wheel type.

Key Features

• Hard, dense, convolute construction produces a consistent, professional finish without undercutting or distorting workpieces
• Conformable design keeps abrasive in contact with complex and irregular part geometries
• Effective on all types of metals, composites, and glass for versatile single-wheel use
• Unique resin system minimizes smearing, reducing post-process surface cleaning time
• Minimizes heat buildup to reduce discoloration and warping risk on heat-sensitive materials
• Suitable for robotic processing and manual bench finishing applications

Compatibility

Designed as an OEM-style replacement or direct-use convolute deburring wheel for standard arbor-mount bench grinders and automated finishing equipment that accept 8-inch diameter convolute wheels.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always power down and de-energize the spindle before mounting or removing the wheel. Inspect the wheel for damage before each use and confirm the arbor size and RPM rating of the equipment matches the wheel specifications. Follow ANSI B7.1 safety requirements for abrasive wheel mounting and guarding.
