3M 7000046039 Scotch-brite Exl Deburring Wheel 8 in Ao

Product Description

The 3M 7000046039 is a convolute deburring and finishing wheel from the Scotch-Brite EXL line, designed for use on metals, composites, and glass. Its hard, dense construction quickly removes burrs, smooths edges, and polishes surfaces in a single operation. The convolute build keeps the wheel running true under load, producing a consistent finish without undercutting or gouging the workpiece. A unique resin system minimizes smearing, and the wheel is formulated to limit heat buildup, reducing the risk of discoloration or warping on heat-sensitive materials. Fabricators, machinists, and finishing technicians working with stamped, laser-cut, or belt-sanded parts are the primary users.

This wheel is suited for bench grinder and automated robotic finishing applications where conformability to complex part geometry is required. It handles deburring of stamped metal parts, laser-cut edges, and post-belt-sanding finish work across a wide range of substrates including ferrous metals, non-ferrous metals, composites, and glass. Its dense, conformable structure maintains abrasive contact on irregular surfaces, making it equally effective in manual and automated processing environments.

Key Features

• Hard, dense convolute construction runs smooth and produces a consistent, repeatable finish
• Conformable structure maintains abrasive contact on complex-shaped and irregular workpieces
• Effective on metals, composites, and glass, reducing the need to change wheels between tasks
• Minimizes heat buildup to protect heat-sensitive substrates from discoloration and warping
• Unique resin system reduces smearing and cuts post-process cleaning time
• No undercutting, gouging, or distortion of the workpiece during deburring or finishing

Compatibility

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

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with abrasive wheel mounting procedures. Always power down and de-energize the grinder or finishing machine before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use, and confirm the spindle speed rating of the machine does not exceed the wheel rating. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
