Precision Miniature Deburring

Junior Mills are scaled-down versions of our famous Midget Mills, designed for intricate work on small parts and in tight spaces.

With 1/8" shanks and proportionally smaller head diameters, Junior Mills provide the same precision-ground quality as standard Midget Mills but in sizes suitable for die grinders, flex shaft tools, and high-speed spindles.
