The design of our indexable thread mill cutters and inserts represent another step forward for thread making applications.
Easy to load inserts are double-sided and 40 mm long for increased thread lengths.
In some cases, the same insert can be used for both left and right hand threads of the same pitch. The complete range is available in Seco®' tough and wear resistant grade F30M, a universal choice for all materials.
Seco® have engineered a range of tool holders with multi-tooth cutter bodies for O.D. and I.D. thread making operations. Shell mill versions are also available and hold up to six inserts which allows for more aggressive threading. Unlike tapping, milled threads can be machined to full depth, even in materials that have already been hardened, with no sacrifice to the thread form, surface finish or accuracy.
