High-efficiency thread mill with end-cutting edge for non-ferrous metals

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

• 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.
