Form G

  • universal contour
  • for all materials
  • low hole straightness deviation
  • low tendency to jam

Form A

  • tight hole tolerance
  • angular entrance and exit bores

Form C

  • angular entrance and exit bores
  • tight hole tolerance

Nose grind

With the change of the cutting geometry, solid carbide gundrills can be optimally adapted to your requirements. For long chipping and hard to machine materials an open special point should be used.
