本文的目的是确定标准和麻花钻的能力扭矩和轴向力，通过螺旋程序进行锐化。对麻花钻的横截面进行了分析和实验研究。基于有限元方法，描述了一个获得扭矩的数学过程。

The objective of this paper is to determine the capable torque and axial force for the standard and twist drill, sharpened by helical procedure. The cross section of the twist drill was both analytically and experimentally approached. Based on the finite element method, a mathematical procedure, in which the torque is obtained, is described.
