	The paper presents numerical analysis results of hot forward extrusion of twist drills. The calculations were made using DEF0RM-3D vi0.0, the simulation programme based on the finite element method (FEM). The numerical analysis of the proces was performer in a three-dimensional state of strain which took thermal phenomena into account. A geometric model employed in the conducted numerical simulation is presented. As a result of the conducted research, force parameters of the proces, distributions of effective strain, reduced stress, and temperaturę could be determined. In effect, it has been proven that twist drills can be formed by extrusion. The obtained results constitute an introduction to a complex analysis of metal forming processes for drills.
