Internal cooling drill bit forming process

The invention discloses an internal cooling drill bit forming process. The internal cooling drill bit forming process comprises the following steps that metal powder and a forming agent are fed into an internal mixer for internal mixing, an obtained material is taken out and cooled after uniform internal mixing, and the material is crushed by a crusher to obtain feedstock for injection molding; the feedstock is fed into a charging barrel of an injection molding machine and heated to a molten state, and the feedstock is fed into a mold to be cooled for forming after being heated and molten; a blank obtained after injection molding is heated, the blank comprises a cutter handle end and a cutting edge end, and during screwing, the cutter handle end is clamped and fixed, and the cutting edge end is rotated, so that a spiral body of a spiral cutting edge and a spiral chip groove part is obtained; the blank obtained through heat preservation and screwing is soaked in a solvent, so that the forming agent is partiall
