HSS twist drill bit Split Point

 

 

HSS twist drill bit Split Point

This drill bit allows precise pilot drilling even on diagonal surfaces. The advance force decreases by 50 %. It has the best possible true running accuracy and therefore produces exact round holes. It has a long tool life and due to its conically strengthened high resistance against fracture.

 

 

 

Features

  • Centre punching is not necessary
  • Safe pilot hole drilling, even in slanting surfaces, in pipes and welds
  • The feeding power is reduced by up to 50%
  • The drill bit facilitates an increase in drilling progress by up to 45%.
  • Regular chip removal and reduction of chip friction
  • Extremely true running and precise round holes
  • No jamming of the main cutting edge and no slipping of the drill bit for through-holes
  • High fracture strength and long life
  • Reduced friction due to reduced external diameter in shank direction
  • Higher breaking resistance due to conically reinforced drilling core
  • Long operating time and fast drilling progress due to chemical thermal method of hardening and accurate cross-ground-finish
