3M 7000120804 Scotch-brite Exl Deburring Wheel 12 Inch

Product Description

The 3M 7000120804 is a convolute deburring and finishing wheel from the Scotch-Brite EXL line, designed for production and fabrication environments where consistent surface quality is required. Built with a hard, dense, and conformable abrasive construction using aluminum oxide, this wheel deburrs, finishes, and polishes metals, composites, and glass in a single operation. At 12 inches in diameter and 3.9 inches in width, it suits benchtop or automated robotic setups and weighs 7 pounds. Fabricators, machinists, and metal finishing technicians working with stamped parts, laser-cut components, or belt-sanded workpieces rely on this wheel for repeatable, smear-free results.

This wheel fits standard production finishing and deburring operations across job shops, metal fabrication facilities, and automated manufacturing lines. It is well suited for finishing stamped or laser-cut metal parts, smoothing surfaces after belt sanding, and processing complex-shaped components in robotic or fixture-mounted applications. The conformable structure keeps the abrasive in full contact with irregular surfaces, making it effective across a range of part geometries without operator adjustment.

Key Features

• Hard, dense convolute construction delivers consistent, repeatable surface finishes without undercutting or gouging workpieces
• Aluminum oxide abrasive handles all types of metals, composites, and glass in a single wheel
• Conformable structure maintains abrasive contact on complex-shaped parts, including in robotic processing setups
• Unique resin system minimizes smearing, reducing post-process cleaning time
• Low heat buildup reduces risk of discoloration or warping on heat-sensitive substrates
• 12 inch diameter and 3.9 inch face width suit benchtop grinders and production finishing machines

Compatibility

Designed for use on standard convolute wheel arbor setups compatible with 12 inch diameter deburring and finishing wheels. Suitable for processing metals, composites, and glass across benchtop and automated production environments.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with abrasive wheel mounting procedures. Power down and lockout the machine before mounting or removing the wheel. Verify that the machine spindle speed rating meets or does not exceed the maximum rated RPM for this wheel before operation. Inspect the wheel for damage before each use and follow ANSI B7.1 safe mounting practices for bonded abrasive wheels.
