Hole thread milling cutter 253

Prețurile sunt orientative. Solicitați oferta și veți obține prețuri mult mai avantajoase.

Design: Ultra-finest grain-solid carbide, with internal supply of coolant and 27° right spiral slots to achieve optimum cutting conditions as well as with 45° countersink bevel. 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 drilling, countersinking and thread cutting 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 tap milling cutter for additional thread types (UNC, UNF, pipe thread etc.) on request. You will further information in the technical appendix.
