Other threading tools are limited in terms of either thread size and/or maximum hole depths they can thread. The new heads, unlike standard thread mills, are single raw disc mills that circular interpolate an entire hole depth and create threads pitch by pitch, which allows for greater achievable depths. The cutting action of the new heads also keeps chip sizes to a minimum and ensures taper-free deep-hole threading.
Smaller, less powerful machine tools can now easily generate big threads because the new heads cut with a single point. The heads thus require less machine power and torque.
