Although diamond tools have a history of nearly a hundred years, the deep hole problem of superhard materials has not been effectively solved. Xinlei Tools has successfully developed a variety of diamond deep hole tools through unremitting efforts and has since solved the problem of non-ferrous metals and superhard materials. Processing problems have been widely used in aviation, aerospace, automotive, electronics, stone and other fields.

Gun drill heads include cemented carbide monolithic sintered drills and cemented carbide photo-type steel drills. Drill rods and drill shanks are made of steel through heat treatment and other processes. The three parts of the drill bit, drill pipe and drill shank are welded into a whole. Welded gun drills can choose different grades of well-known alloy materials for reasonable tool design according to the different materials to be processed. For special materials, different types of layers can also be used to deal with it.

The part is welded into a whole, or it can be made of all solid cemented carbide, that is, the drill bit, drill rod, and drill shank are all solid cemented carbide. Because the radial runout of the solid carbide gun drill is small, its life expectancy is also higher than that of the welded gun drill.

Supply dimension: the diameter of 3.1mm to 45mm can be up to 4000mm Hard alloy gun drill is also called deep hole drilling, which represents advanced and efficient hole processing technology. It can not only be used to process deep holes (diameter ratio 1:25), but also can be used to process shallow holes (diameter ratio 1:1). It is welded together by drill shank, drill pipe and bit three parts. There is a hole in the middle which is suitable for drilling cast iron, carbon steel, copper, aluminum alloy and alloy steel etc. The drill hole, boring hole and reaming hole are completed once. The precision of the tool can be machined to high precision (it6-8), fine straightness (0.16-0.33mm / 1000mm), low roughness (ra3.2-ra0.1) hole. The drilling speed is 30 to 100 meters per minute. At present at home and abroad in shipbuilding, automobile, engine, locomotive, chemical machinery, oil pump, mining machinery and hydraulic parts and other industries are widely used.
