Double Margin Jobber Length Drills

Jobber Length Cobalt.
Designed for tough applications in titanium, stainless and heat treated skin and engine shrouds.

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.
