3M 7000120793 Convolute Deburring Wheel 10 Inch Ao

Product Description

The 3M 7000120793 is a convolute deburring and finishing wheel built for high-throughput metalworking and fabrication environments. The wheel uses an aluminum oxide abrasive bonded in a hard, dense convolute construction that deburrs, finishes, and polishes metals, composites, and glass in a single pass. At 10 inches in diameter and 2.6 inches wide, it is sized for bench-mounted or automated arbor setups. The unique resin system minimizes smearing on finished surfaces, and the wheel is engineered to shed heat during use, reducing the risk of discoloration or warping on heat-sensitive workpieces. Licensed fabricators, tool-and-die shops, and automated finishing lines are the primary users of this product.

This wheel is well suited for deburring stamped parts, laser-cut sheet metal, and machined components. Its conformable structure keeps the abrasive in consistent contact with irregular or complex-shaped surfaces, making it a practical choice for robotic and automated processing cells. It also performs well as a follow-up finishing step after belt sanding, where edge refinement and surface consistency matter. Applications span general metal fabrication, aerospace component finishing, composite part processing, and glass edge work.

Key Features

• Hard, dense convolute construction delivers consistent, repeatable surface finish without undercutting or gouging
• Aluminum oxide abrasive effective on metals, composites, and glass
• Conformable wheel body maintains abrasive contact on complex and irregular part geometries
• Resin system minimizes surface smearing, reducing post-process cleaning time
• Low heat buildup reduces risk of thermal discoloration and substrate warping
• Suited for both manual bench use and robotic or automated finishing cells

Compatibility

Designed as an OEM-style replacement or direct-fit convolute deburring wheel for standard arbor-mounted bench grinders and automated finishing equipment accepting 10-inch diameter convolute wheels.

Installation Notes

Installation should be performed by a qualified fabricator or machine operator familiar with abrasive wheel mounting procedures. Always de-energize and lock out the machine before mounting or removing the wheel. Verify arbor size, flange fit, and maximum operating speed rating before use. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
