Product Description

Description of tungsten carbide Gundrill blanks:

Carbide Gun Drill

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 woodwind 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.

Carbide Gundrill Blanks

We offers a complete line of deep hole drills and gundrills. Gundrill blanks can be full-length sticks, cut to length heads, and can have preformed presharpening angles included. Round or other shaped coolant holes including single hole, double hole or kidney holes can be manufactured.

Carbide Gundrill Blanks FamilyStandard gundrill extrusions up to 12.2” long are available in diameters ranging from 0.098” to 0.770” OD and are available with three different coolant hole geometries. Gundrill heads requiring diameters greater than 0.770” OD can be manufactured with one or two coolant holes.

The advantages of this Carbide Gun Drill Blanks are-

Efficient quality in appropriate price

Accurate dimensions with customer demands

Ensured durability with reliable performance

"Carbide gun drill," also known as deep-hole drilling, representing advanced and efficient hole processing technology. It not only can be used to process deep holes (diameter longer than 1: 250), but can also be used to process shallow holes (diameter longer than 1: 1). It consists of the drill shank, drill pipe, drill three parts are welded together in the middle with a through-hole for drilling in cast iron, steel, copper, aluminum, steel and the like. Gun drill will be drilling, boring, reaming once completed, can be processed in one pass precision (IT6-8 level), fine straightness (0.16-0.33mm / 1000mm), low roughness (Ra3.2- Ra0.1) holes. Its drilling speed of 30-100 m / min or more. At home and abroad in shipbuilding, automobiles, engines, locomotives, chemical machinery, glib pumps, mining

Mechanical and hydraulic parts and other industries widely used. Specifications: Φ3.5mm ~ Φ45mm
