New Products

Realize high accuracy and longer tool life in ultra-high-speed drilling in machining center or turning machine where chip jamming is easy to occur.

  • Even the traditional 3 times higher feed can also be stable processing by adopting good geometry of cutting edge and flutes for reducing thrust cutting force, chip breaking and evacuation.
  • Improved chip breaking performance and realized outstanding chip evacuation in work rotation turning machine as well.
  • Even if it is stunning ultra-high-speed feed, but also can achieve long processing life, high-precision machining.
