It is expected that a twist drill will give somewhat different aspects on the deflection and stresses compared with a straight bar of the same cross-section. In the first part of the present research, we proved theoretically that the deflection of a twist drill due to bending becomes a particular space curve. The surface stresses of the drill due to torsion, obtained experimentally by the strain gauges, are shown in this report also.
