JBO Thread
Milling Cutters


An added value for modern CNC machining

Long time life, shortest processing times and an excellent surface quality - these are just three advantages of our solid carbide thread milling cutters, -wide range thread milling cutters, -drill thread milling cutters and indexable thread milling cutters.

Do you need special thread milling cutters? No problem!
We analyze your process of machining and work out a cost and quality optimized solution.

General advantages of thread milling


  • Threads to different tolerance classes can be produced with same cutter

  • Tool breakage does not necessarily entail scrapping of the workpiece

  • Less power needed for cutting internal threads

  • Short machining times due to high cutting speeds

  • Excellent thread surface finish

  • Short chips, hence no chip problems

  • Right and left hand threads can be produced in blind or through holes by the same cutter

  • Low cutting forces enable threads to be cut in thin wall workpieces

  • Cutting speeds and feeds can be matched individually to workpiece material

  • No change of cutter spindle direction of rotation required

  • No special tapping chucks required, standard chucks suffice

  • Threads can be cut to exact depth

  • Threads can be cut down to near bottom of blind holes

  • Start of thread accurately determined by NC programme
