Cobalt jobber drills offer increased hardness, toughness and better wear resistance compared to regular HSS

Titanium nitride (TiN) coating increases wear and heat resistance while improving chip flow and higher lubricity

Parabolic flute design facilitates effective chip evacuation for deeper hole drilling
