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.

High-Grade Internal threading

The AT-2 thread mill with end-cutting edge for high hardness steels is ideal for highly difficult high hardness steel applications. The risk of sudden tool breakage can be minimized by breaking chips into small and manageable pieces and evacuating them smoothly. Since no pilot hole is required, process integration and the risk of breakage can be avoided.

Features

• Helical drilling + threading can be done simultaneously.

No pilot hole is required! Stable machining with minimal cutting chip trouble made possible.

• Newly developed DUROREY coating enables superior heat resistance and high toughness optimized for high-hardness steel milling!

(1) Special cutting edge shape suppresses bending of the tool.

(2) Left-hand cut configuration enables climb milling to prolong tool life.

(3) Roughing teeth are added to distribute the load.

Long and stable tool life with higher thread quality compared to cutting taps

The high-efficiency thread mill AT-2 R-SPEC (ThreadRacer) is engineered to dramatically reduce machining time in non-ferrous metal applications such as aluminum alloy by its continuous helical cutting ability, which combines drilling and threading into a single process. The AT-2 R-SPEC is also effective as a countermeasure against cutting position misalignment in cast holes.

Features

• Helical drilling + threading can be done simultaneously.

• DLC-IGUSS coating

(1) Left-hand cut configuration enables climb milling to prolong tool life

(2) Superior chip evacuation　*Tool DC = φ4.6 or more

(3) Special cutting edge shape suppresses bending of the tool
