Taper Length Oil Hole Drills are designed for tough jobs when higher feeds and increased speeds of 30% or more are used. They were originally used for high production work on screw machines and turret lathes. Coolant (air, oil, or vapor mist) supply developments have made oil hole drills adaptable to a wide range of drilling operations. All ICS oil hole drills are compatible with all standard coolant delivery systems. For extra (100-300%) wear, specify titanium nitride coated oil hole drills.

Extra Long Taper Shank Oil Hole Drills are designed for deep hole drilling and where heavy feed conditions are required. Coolant flow virtually eliminates chip packing and other problems common to deep hole drilling applications.
