Solid carbide thread mills
Premium spiral fluted solid carbide thread mills for internal threads with and without internal cooling
The Karnasch solid carbide thread mills enable the production of threads in steel as well as in abrasive materials.
In sizes from M 3 to M 12, with a diamond coating, a 30° spiral and an additional countersinking step, the thread mills can be used for the machining of graphite and GRP/CRP.
Due to the special coating for steel processing up to 70 HRC, logarithmic relief grinding and tool cooling, the thread mills from M3 to M8 are the best choice for achieving outstanding tool lives (available from August 1, 2019).
The combination of logarithmic relief grinding, internal coolant supply and cooling leaks at each cutting edge increases the process reliability and tool life of the solid carbide thread mills considerably.
