Diamond insert single-edged gun drill
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.

Operation mode and processing function of deep hole gun drill
Gun drill is generally welded together by drill handle, drill pipe and drill bit. There is a through hole in the center of the gun drill, which is the channel for the cutting fluid to enter the cutting area. The drill bit is the key part of the whole gun drill. Data is cemented carbide

Gun drill is an effective tool for deep hole processing, and its processing range is very wide, from glass fiber, Teflon and other plastics to deep hole processing of high-strength alloys (such as P20 and Inconel). In deep hole processing with strict tolerance and surface roughness requirements, gun drill can ensure the dimensional accuracy, position accuracy and straightness of the hole.
