JBO precision thread milling cutters: an added value for modern CNC machining

Long service 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

Special advantages of type GFS thread milling cutter with chamfering capability

  • High productivity due to chamfering and thread milling with just one tool without tool changing
  • Reduction of both cutting time and non-cutting time in machining cycle
  • Saving of tool magazine places
  • Elimination of tool changing time
  • Reduction of setting time

Special advantages of type GFM wide range thread milling cutter

  • Cutter can cut threads of identical pitch on a wide range of diameters
  • Low tooling costs for large threads
  • Neck between cutter teeth and shank allows appreciably deeper threads to be cut by a 2nd thread milling cycle

Special advantages of type GFE / GFT thread milling cutter

  • Small diameter threads starting at M1 can be produced
  • Deep threads (3xD) can be produced

Special advantages of type BGF / BGF3 drill thread milling cutter

  • High productivity due to drilling, chamfering and thread milling with just one tool without tool changing
  • Reduction of cutting and non-cutting times in machining cycle
  • Saving of two tool magazine places
  • Fully cut thread only 1.3 x pitch shorter than depth of drilled hole
  • Both blind and through holes can be drilled and threaded

Special advantages of circular drill thread milling cutters type BGFS-W / BGFS-H

  • Allows the usage of drill thread milling cutters in soft and hardened steel materials
  • High productivity due to drilling and thread milling with just one tool without tool changing
  • Reduction of cutting and non-cutting times in machining cycle
