Thread Mill 「AT-1」English version Evolution from conventional 2-pass cutting to 1-pass cutting by preventing bending, thus reducing cutting time
Conventional thread mills often require several passes to generate a thread. The AT-1’s revolutionary capability to generate threads in one pass lies in its unique tool geometry. The unequal spacing and variable lead flute of the AT-1 minimizes vibration, thereby enables superior and consistent surface finish.
Conventional right-hand helix thread mill is prone to deflection as the cutting process begins from the tip. In contrast, a first of its kind with a patent in Japan in the thread mill category, the AT-1’s right-hand cut and left-hand helix geometry begins the cutting process from the shank side, thereby reduces deflection. With the elimination of zero-cutting, which is used for the correction of deflection, longer tool life can be achieved.
