One Pass Thread Mill

Thread mills are tools designed to cut threads by milling. Thread mills are used on numerically controlled machining centers (NC) that have simultaneous, triaxle control and helical interpolation functions. In comparison to general tapping, thread milling is more stable with less cutting condition limitations in terms of chip management and coolant lubricity.

Features

• 1-pass process enables high quality internal threading.

(1) Right-hand cut and left-hand helix geometry prevents bending.

(2) Unequal spacing and variable lead flute geometry minimizes vibration.

(3) EgiAs coating for exceptional wear resistance and toughness.

• Use RPRG to reduce the workload
  RPRG is the reference value of tool radius offset. Conventionally, the tool radius value is entered during setup as a parameter of the NC system, which is corrected by checking the thread with a gauge. Now, the process of correction can be simplified by simply inputting the RPRG value as indicated on the tool shank.
