e/Gun drill

Information
has gloss	eng: Gun drills are straight fluted drills which allow coolant (either compressed air or a suitable liquid) to be directed through the drill's body, directly to the cutting face. They are used for deep drilling (depth to diameter ratios of 100 to 1 or more are possible), of which gun barrels are the obvious example. Other uses include the manufacture of woodwind instruments, such as uilleann pipes, as gun-drills are capable of drilling long straight holes in metal, wood and some plastics. The coolant provides lubrication and cooling to the cutting edges as well as ejecting the swarf or chips back out the drills length. Modern gun drills take advantage of carbide tips to reduce expense and prolong life. The images show the coolant holes in the drills shank and tip, as well as full length (12 mm dia × 635 mm long) gun drill and the carbide tip of a second (25 mm) gun drill.
