	The study presents a new method, developed by the authors, for producing twist drills by extrusion using a three-slide forging press. The method consists in using two sectional dies with specially shaped impressions that allow the removal of a ready drill from the die without unscrewing. The study describes the main assumptions of the new method for twist drill extrusion, discussing benefits offered by this method when compared to the conventional process for producing twist drills by extrusion using a monolithic die. In order to verify the proposed solution, dies conforming to the assumptions of the new method were designed and executed. Experimental tests were conducted under laboratory conditios using a three-slide forging press. The model of the material used in the experiments was assigned the properties of Pbl lead. As aresult of the experiments, the theoretical assumptions of the new method could be examined and its practical application verified. Ałso, ideas for further research aimed at better understanding of the new technology for producing twist drills by extrusion are presented.
