The invention relates to a heating drilling tool for a V-shaped workpiece. The heating drilling tool comprises a supporting base. The two ends of the upper surface of the supporting base are symmetrically provided with supporting seats. Arc-shaped plates at the two ends of the V-shaped workpiece are arranged in the supporting seats respectively. A supporting column is arranged in the middle of the upper surface of the supporting base. The upper end of the supporting column abuts against the forked root of the V-shaped workpice. The supporting seat at one side is provided with a rotary lifting column. The end of the rotary lifting column is provided with a supporting plate. The end of the supporting plate is provided with an electric heating ring. A ring center ring of the electric heating ring is matched with the upper end of the V-shaped workpiece. According to the heating drilling tool, the V-shaped workpiece is inversely arranged on the supporting seats and the supporting column, supporting stability is high, drilling machining of a drill bit is facilitated greatly, drilling efficiency is improved, and the yield is increased; and the upper end of the V-shaped workpiece is heated through the electric heating ring, heat drilling machining is achieved, and machining quality is improved.
