Our mission at Micro-Mark is to be your source for hard-to-find miniature tools and hobby tools at low prices. Micro-Mark's mini taps and dies are designed with modelers and hobbyists in mind. Use micro thread taps for putting threads in a hole made with a tap drill. Use our micro dies for accurately putting threads on a rod. All of our dies are made of high-speed steel with a 13/16 inch outside diameter and are adjustable for thread fit allowance. You can always buy your individual taps and dies and tap and die sets with confidence because we guarantee your satisfaction with our no-quarrel policy. Use our tools to give every project a professionally finished look.
