ZSD series U-drill


  • Adopts unique waved-edge geometry structure, steady cutting and smooth chip evacuation
  • Single insert, double balanced radial run-out control, achieve high hole-making accuracy and precision under long overhang occasion
  • Apply wiper technology, excellent hole surface quality and hole diameter dimension consistency.
  • Strong impact-resistance and high rigidity structure design, helping achieving high speed, high efficiency, high stability machining
  • Economical four-edges inserts type, suitable for Deep-hole drilling in 2D~5D


There are three types of geometry, suitable for High efficiency and stability machining in multiple materials
  • -EM: Low carbon soft steel geometry, prevents chip-wrap from occurring
  • -XM: General-purpose geometry, realizes low resistance stability machining operation.
  • -LM: Geometry for Stainless steel and sticky chips steadily
