High quality welding alloy gun drill factory

Gun drill is a widely used tool in deep hole machining.

The principle of gun drilling processing is to use the method of internal cooling and external chip removal, which forcibly removes chips through high-pressure oil inside the drill pipe. Therefore, there is no need for chip removal during the processing, and the processing aspect ratio can reach over 200 times. The aperture size, deviation, and inner hole roughness of gun drilling can all reach a high quality level. It has been widely used in industries such as automotive parts, hydraulics, molds, military industry, and petroleum.

Usually, gun drills are manufactured using a brazing process, which consists of three parts: the drill handle, drill rod, and drill bit welded together. There is a through-hole in the middle of the gun drill, which is the channel for cutting fluid to enter the cutting area.

 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 drilling—a depth-to-diameter ratio of 300:1 or more is possible.Gun barrels are the obvious example; hence the name. Other uses include moldmaking, diemaking, and the manufacture of woodwindmusical 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.
