Technological process of production of our Solid carbide twist drill bits: powder process → formula according to the use requirements → wet grinding → mixing → smash → dry → sieving → add binder → dry again → get the mixture after sieving → pelletize → pressing → forming → sinter-hip → forming (blank) → blanks checking → finishing product machining → cleaning → inspection of the finished product → packaging → entering warehouse.

Solid carbide twist drill bits develops with the need of high-efficiency machining in automobile industry and machining the plastic reinforced fiberglass circuit board in IT industry, as the miniaturization of computers and mobile phones, the diameter of the Solid carbide twist drill bits will develop towards the direction of the small, now has 0.08mm diameter of the solid carbide twist drills.

Solid carbide twist drill bits is drilling tool with good toughness and high wear resistance. It has a long service life with good quality. But because of it is made of tungsten carbide materials, so it is more brittle compared with the HSS material. The Solid carbide twist drill bits is mainly used for machining iron casting, stainless steel and the material that difficult to machining.
