What are Thread Mills?

Solid Carbide Thread mills have become the ideal
choice when it comes to producing threads on a VMC (Vertical Machining Center)
or CNC mill. Thread mills are made from solid carbide and have several advantages over taps. A tap is completely engulfed by the material which builds
up resistance and can cause breakage. A broken tap often "scraps" the expensive
part being worked on. The diameter of a threadmill is smaller than the
finished thread size that is being cut. The solid carbide thread mill rapidly
circular interpolates the desired thread with a much smaller point of cutting
contact, resulting in much less cutting resistance. Because of the smaller
cutting diameter, if a threadmill eventually wears out and breaks prior to
being detected, the tool just falls into the hole leaving no damage to the
thread or the expensive part you are working on.
