Three pointed and seven sharp edges take the lead, with crescent arc grooves divided on both sides. The outer edge is further grooved, and the horizontal edge is ground low, narrow, and sharp.The reason why group drills are superior to other drills: 60% of the axial resistance of standard Fried Doug

Superalloy refers to a class of metal materials based on iron, nickel and cobalt, which can work for a long time under the action of high temperature above 600 ℃ and certain stress; and has high high temperature strength, good oxidation resistance and corrosion resistance, Good fatigue properties, f

PreambleDue to the problems of difficult chip removal, high straightness requirements and difficult tool design in the deep hole machining of aero-engine casings, the machining efficiency is generally low [1]. The deep hole of a certain type of aero-engine accessory transmission casing has always be

A carbide end mill is an extremely fast cutting tool. These cutters are manufactured from ultra-fine particles of tungsten carbide. This material is highly durable and has a long service life. This cutting tool has high strength and wear resistance. Its high cutting speed makes it very suitable f

Drilling through hard material can be a difficult task for the drill bit. It would help if you had the right tool to do this. While we often hear that solid carbide drill bits are a better solution for hardened steel, others believe that cobalt drilling bits are also irreplaceable for drilling sta
