Solid carbide thread mill Design: The milling principle results in an exact thread depth, a very high surface quality in the thread, process-reliable machining of difficult to cut materials and thread production very close down to the base. Application: For regular metric threads (both right and left thread) according to ISO DIN 13 for through holes and blind holes. Note: Solid carbide thread mill for additional thread types (UNC, UNF, pipe thread etc.) on request. You will further information in the technical appendix.
