Hi–Lok^® Sizes Piloted Double Margin Drills

Jobber Length Cobalt 135° Split Point
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 stabilized and true cylindrical geometry is established. Smooth accurate holes are produced and reaming can often be eliminated.
