3M 7100126839 Deburring Wheel 8 Inch Silicon Carbide

Product Description

The 3M 7100126839 is a convolute deburring wheel designed for edge finishing, deburring, and surface conditioning on metal workpieces. Built with silicon carbide abrasive at a fine grade and density 8, this wheel delivers consistent cut and controlled aggressiveness across the face. It measures 8 inches in diameter with a 7/16-inch face width and a 3-inch center hole, and it is rated to a maximum of 4,500 RPM. Machinists, fabricators, and finishing technicians use this wheel in production and job-shop environments where repeatable edge quality is required.

This wheel is suited for bench top motor setups, inline sanders, and manual backstand configurations. The convolute construction layers abrasive-coated fiber uniformly around the core, which provides even pressure distribution and a consistent finish across the full face width. It is commonly used on ferrous and non-ferrous metals where burr removal and light surface blending are the primary objectives. Silicon carbide is well matched to harder, more brittle materials and non-ferrous alloys.

Key Features

• Silicon carbide abrasive for effective cutting on non-ferrous metals and hard materials
• Fine grade with density 8 hard rating for controlled stock removal and consistent finish
• Convolute wheel construction provides even face contact and uniform wear
• 4,500 RPM maximum speed rating
• 3-inch center hole fits standard bench motor and backstand arbors
• Compatible with bench top motors, inline sanders, and manual backstand tooling

Compatibility

Designed for use with bench top motors, inline sanders, and manual backstand equipment. The 3-inch center hole is a common arbor size for industrial deburring and finishing machines in this wheel diameter class.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician following the equipment manufacturer's arbor and flanging specifications. Always power down and de-energize the machine before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the 4,500 RPM maximum rating of the wheel before operation. Inspect the wheel for damage before each use and dress the face if glazing is observed during service.
