Applications
This tool is ideal for manufacturing conical pipe threads in connection technology, plant construction, and general mechanical engineering. The design for universal use makes the cutting insert an excellent choice for production companies that regularly machine steel, stainless steel, and non-ferrous metals.
Special features
The PVD coating RT315 supports smooth chip evacuation and protects against premature wear. Thanks to the precise 60° full profile, the thread is shaped accurately and cleanly, which favors a reliable sealing effect of the finished NPT connection.
