Sterlingdeep Hope Gun Drill Bits Diameter: 10 Millimeter (Mm)

We manufacture, export, distribute, trade and supply Gun Drills to our clients in Dezhou, Shandong, China. Gun drills are straight fluted drills which allow cutting fluid to be injected through the drill's hollow body to the cutting face. They are used for deep drillingA AcA A A A a depth-to-diameter ratio of 300:1 or more is possible. Gun barrels are the obvious example; hence the name. Other uses include mold making, diemaking, and the manufacture of wood wind musical instruments, such as uilleann pipes, as gun drills can drill long straight holes in metal, wood, and some plastics. The coolant provides lubrication and cooling to the cutting edges and removes the swarf or chips from the hole. Modern gun drills use carbide tips to prolong life and reduce total cost when compared with metal tips.
