3M 03900 Deburring Wheel Flange 3 in Min Dia

Product Description

The 3M 03900 is a deburring wheel flange designed to mount and secure deburring wheels during rotary finishing and deburring operations. The flange accommodates wheels with a minimum diameter of 3 inches and a 1-1/4 inch center hole, holding the abrasive wheel firmly against the drive arbor for consistent contact and controlled material removal. This hardware component is a standard mounting accessory used in metal fabrication, pipe work, and HVAC sheet metal shops where burr removal from cut edges is part of the workflow. Tradespeople and fabricators working with tubing, conduit, or duct components rely on properly fitted flanges to keep deburring wheels seated and running true.

This flange is suited for use in trade and light industrial settings where 3 inch or larger deburring wheels are run on bench grinders, angle grinders, or dedicated deburring machines. It is particularly relevant in plumbing and HVAC applications where copper, steel, or aluminum tubing requires clean, deburred ends before fitting connections. The 03900 is sold as a single unit, making it practical as a direct replacement for a worn or missing flange in an existing setup.

Installation Notes

Installation is typically performed by machinists, fabricators, or trade technicians familiar with rotary abrasive tooling. Always power down and disconnect the grinder or deburring machine from its power source before removing or installing a wheel flange. Verify that the wheel diameter and hole size match the flange specifications before mounting. Follow the tool manufacturer torque and guard requirements per applicable OSHA and ANSI abrasive wheel standards.
