Piloted Double Margin Drills

  • Designed for close tolerance drilling in titanium, stainless, heat treated material and aluminum alloys. When the drill point penetrates enough for the second margin to contact the wall of the hole, the point is stabiized and true cylindrical geometry is established. Smooth accurate holes are produced and reaming can often be eliminated.
