3M 7100078001 Deburring Wheel 12x1x5 in 11S Fine

Product Description

The 3M 7100078001 is a convolute deburring wheel engineered for high-production metal finishing applications. Built on a hard, durable density-11 core with fine-grade silicon carbide abrasive mineral, this wheel delivers firm, consistent cutting action while maintaining enough surface feel for controlled deburring and edge blending. The convolute winding construction layers the abrasive uniformly around the core, producing repeatable results across the wheel's full usable life. At 12 inches in diameter with a 1-inch face width and 5-inch arbor hole, it fits standard bench or pedestal deburring machines used in fabrication and machining shops.

This wheel is suited for deburring, light grinding, and surface conditioning on ferrous and non-ferrous metals. Its fine silicon carbide abrasive grade makes it appropriate for finishing operations where edge quality and surface consistency matter — such as removing sharp burrs from stamped, punched, or machined parts prior to assembly or coating. Metal fabricators, machinists, and industrial maintenance technicians are the primary installers and operators of this wheel type.

Key Features

• Fine-grade silicon carbide abrasive mineral for controlled cutting and smooth finish
• Density-11 hardness — firmest XP-grade construction for maximum durability
• Convolute winding on a rigid core ensures uniform abrasive distribution throughout wheel life
• 12-inch diameter x 1-inch face x 5-inch arbor hole fits standard deburring machine spindles
• Weighs 2.82 pounds — compatible with typical bench and pedestal machine weight ratings

Compatibility

Designed for use on standard bench-style or pedestal deburring and finishing machines accepting a 5-inch arbor hole and wheels up to 12 inches in diameter. Confirm machine RPM rating against wheel specifications before mounting.

Installation Notes

Installation of convolute deburring wheels should be performed by a qualified technician following ANSI B7.1 safety standards for abrasive wheel mounting. Power down and lockout/tagout the machine before changing wheels. Inspect the wheel for cracks or damage before mounting, and ensure flanges, blotters, and arbor hardware are clean and undamaged. Run the wheel at no-load speed for at least one minute behind a guard before returning the machine to service.
