3M 7100053421 Deburring Wheel 3in Ceramic Medium Grade

Product Description

The 3M 7100053421 is a ceramic abrasive deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. Built as a unitized wheel with a density rating of 6 and a hard density grade, it delivers consistent cut and finish throughout the life of the wheel. The 3-inch diameter and 3/4-inch face width make it well-suited for die grinder applications where controlled material removal is needed. The ceramic abrasive construction provides durability and cut-rate consistency under moderate to heavy use conditions. This wheel is installed and operated by machinists, fabricators, and maintenance technicians working in metal finishing environments.

This deburring wheel is intended for use with die grinders in fabrication shops, maintenance facilities, and production environments. It is appropriate for deburring drilled holes, blending weld seams, and cleaning up cut edges on ferrous and non-ferrous metals. The 1/4-inch center hole fits standard die grinder mandrel sizes commonly found in trade and industrial settings. With a medium abrasive grade and hard density construction, it handles moderate stock removal while leaving a consistent surface finish.

Key Features

• Ceramic abrasive material for consistent cut rate and extended wheel life
• Unitized wheel construction maintains abrasive performance throughout full wheel thickness
• Density 6 hard grade provides firm structure for controlled deburring and blending
• 3-inch diameter and 3/4-inch face width sized for die grinder use
• 1/4-inch center hole fits standard die grinder mandrels
• Medium abrasive grade balances material removal with surface finish quality

Compatibility

Designed for use with die grinders accepting a 1/4-inch mandrel arbor. Suitable for ferrous and non-ferrous metal deburring and surface finishing applications.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel safety practices. Ensure the die grinder is powered off and disconnected from its air or electrical source before mounting or removing the wheel. Verify that the grinder's rated RPM meets or exceeds the wheel's maximum operating speed before use. Inspect the wheel for damage prior to each use and never operate a cracked or compromised abrasive wheel.
