3M 7010329849 Scotch-brite Exl Deburring Wheel 4 Inch Fine

Product Description

The 3M 7010329849 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 delivers fast, consistent deburring, finishing, and polishing in a single pass. At 4 inches in diameter with a fine grit rating, the wheel suits bench grinder and arbor-mounted setups commonly used in fabrication, machine shops, and light manufacturing. Its unique resin system minimizes smearing and reduces cleanup time, while the construction limits heat buildup to protect heat-sensitive substrates from discoloration or warping.

This wheel is well suited to deburring stamped parts, laser-cut components, and castings, as well as finish work following belt sanding operations. The conformable structure keeps the abrasive in consistent contact with irregular and complex-shaped workpieces, making it a practical choice for both manual and robotic processing environments. It handles a range of materials with a single wheel, reducing the need for multiple tooling changes during production runs.

Key Features

• Hard, dense, convolute construction produces a consistent finish without undercutting, gouging, or distorting the workpiece
• Fine grit rating suitable for finishing and light deburring on metals, composites, and glass
• Conformable design maintains abrasive contact on complex-shaped and irregular surfaces
• Unique resin system minimizes smearing and reduces post-process surface cleaning
• Low heat buildup reduces risk of discoloration and warping on heat-sensitive materials
• Compatible with robotic and automated processing applications

Compatibility

Designed as an OEM-style convolute deburring wheel for arbor-mounted bench grinders and automated finishing equipment operating on metals, composites, and glass substrates.

Installation Notes

Installation is typically performed by a machinist or fabrication technician. Always power down and lock out the grinder or arbor unit before mounting or removing the wheel. Verify that the wheel bore, arbor size, and maximum RPM rating of the equipment match the wheel specifications before operation. Inspect the wheel for damage prior to each use and follow applicable ANSI safety standards for abrasive wheel mounting and guarding.
