Benefits of Thread Mills

Right on size! Using the machine’s cutter compensation, a thread’s major diameter can easily be altered to produce precise threads. Tool life is increased over common tapping because wear can be compensated when using thread mills.

No more broken taps! When taps break it can be very costly to salvage the work piece. If a thread mill breaks during a cut, a new thread mill can re-enter into the hole and start from the beginning with very little time lost. Producing threads in large or expensive parts is no longer a risk. A presetter is suggested for tool height accuracy. Multiple diameters? No problem. A thread mill is simply an end mill with the thread form and a specific pitch. The machine can be programmed to helically interpolate to the desired diameter. A 1/4-20 thread mill can produce a 1/2-20 or even a 7/8-20 thread making it an excellent choice for uncommon thread sizes or large diameter threads.
