Solid carbide thread milling cutter TMC SP for inner thread
Design: Ultra-finest grain-solid carbide, with internal supply of coolant (from thread size M4) and 27° right spiral slots to achieve optimum cutting conditions. 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 thread cutting and countersinking with a single tool. For regular metric threads (both right and left thread) according to ISO DIN 13 for through-holes and blind holes. Note: Solid carbide thread milling cutter for additional thread types (UNC, UNF, pipe thread etc.) on request. You will further information in the technical appendix.
