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

Thread mill with end-cutting edge for high hardness steels Features
  • Helical drilling + threading can be done simultaneously.

No pilot hole is required! Stable machining without chip trouble

No pilot hole is required! Stable machining without chip trouble.

  • Newly developed DUROREY coating enables superior heat resistance and high toughness optimized for high-hardness steel milling!
1Special cutting edge shape suppresses bending of the tool.
2Left-hand cut configuration enables climb milling to prolong tool life.
3Roughing teeth are added to distribute the load.
  • 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.
