3M 7000046064 Scotch-brite Exl 8 Inch Deburring Wheel Fine

Product Description

The 3M 7000046064 is a convolute deburring and finishing wheel from the Scotch-Brite EXL line, built for professional metalworking, fabrication, and surface prep applications. The wheel features a hard, dense, conformable construction that deburrs, finishes, and polishes metals, composites, and glass in a single pass. At 8 inches in diameter and 2.5 inches wide, it fits standard bench grinders and automated finishing equipment. Fine grit abrasive cuts aggressively enough to remove burrs while leaving a smooth, clean surface without undercutting or distorting the workpiece. The unique resin system minimizes smearing and heat buildup, reducing risk of discoloration or warping on heat-sensitive materials.

This wheel is suited for production and job-shop environments where consistent surface quality is required. Common applications include deburring stamped or laser-cut parts, finishing after belt sanding, and polishing operations on complex geometries. Its conformable nature keeps abrasive in full contact with irregular or contoured surfaces, making it a reliable choice for robotic and automated finishing cells as well as manual bench work. Fabricators, machinists, and metalworking professionals working with steel, aluminum, composites, and glass are the primary users.

Key Features

• Hard, dense, convolute construction runs smooth and produces a consistent finish across the wheel life
• Conformable abrasive stays in contact with complex-shaped and contoured workpieces
• Effective on metals, composites, and glass — one wheel handles multiple material types
• Unique resin system minimizes smearing, reducing post-process surface cleaning time
• Minimizes heat buildup to protect heat-sensitive substrates from discoloration and warping
• Suitable for both manual bench grinding equipment and robotic automated processing cells

Compatibility

Designed as an OEM-style replacement and standard-fit convolute deburring wheel for bench grinders and automated finishing equipment accepting 8-inch diameter convolute-style wheels.

Installation Notes

Mounting and dressing of convolute deburring wheels should be performed by a qualified machinist or metalworking technician. Always power down and lockout the grinder or finishing machine before mounting or removing the wheel. Verify that the spindle speed rating of the machine does not exceed the maximum RPM rating for this wheel before operation. Eye protection and appropriate PPE are required during use.
