CNC gun drills are single flute tools designed to drill extra deep holes on conventional CNC machining centers without the need for specialized gun drill equipment. These precision deep hole drills have one piece ultra fine-grain carbide flute construction with no brazed head. The nano-A coated point improves abrasion resistance at the cutting edge, and increases the temperature at which these drills can effectively operate. The specialized point grind is a universal design that is well-suited to the job shop environment. Drilling depths of over 75xD can be reached with EB 100 CNC style gun drills.
