3M 7100040577 Convolute Deburring Wheel 12 Inch

Product Description

The 3M 7100040577 is a convolute-constructed abrasive deburring wheel designed for mid-range aggressiveness and hardness across a broad range of surface finishing tasks. Built with a tough, layered construction, this wheel handles deburring, edge radiusing, blending, polishing, and final finishing on metal alloys, plastics, and composites. It measures 12.4 inches in diameter and 2.6 inches in face width and weighs 5.25 pounds. Metalworking shops and fabrication technicians rely on this wheel for consistent results when removing burrs or refining edges on production runs and repair work alike.

This deburring wheel is suited for bench-mounted or pedestal-style finishing equipment found in metal fabrication shops, machine shops, and light manufacturing environments. It performs best when consistently presented with sharp edges or fresh metal burrs. The wheel can be dressed to restore cutting action, making it practical for extended-use applications across a range of ferrous and non-ferrous alloys as well as select plastics and composite materials.

Key Features

• Convolute construction delivers mid-range hardness and aggressiveness for reliable deburring and edge finishing
• Wheel edge can be dressed to maintain effective cutting action on metal alloys, plastics, and composites
• Operates in both clockwise and counterclockwise directions for flexible mounting setups
• Resists smearing for cleaner surface finishes and reduced post-process preparation
• Minimizes heat buildup to protect heat-sensitive base materials during finishing

Compatibility

Designed as an OEM-style replacement or direct-use convolute deburring wheel for bench and pedestal finishing equipment accepting 12-inch diameter abrasive wheels.

Installation Notes

Installation should be performed by a qualified metalworking or machine shop technician familiar with bench grinder and finishing wheel safety practices. Disconnect and lock out power to the finishing unit before mounting or removing the wheel. Confirm that the spindle speed rating of the machine does not exceed the rated speed of the wheel before operation. Follow ANSI B7.1 safety guidelines for the handling, storage, and use of abrasive wheels.
