The invention relates to a special drilling tool for a V-shaped piece. The special drilling tool for the V-shaped piece comprises a supporting pedestal. Supporting bases are symmetrically installed at the two ends of the upper surface of the supporting pedestal. Arc-shaped plates at the two ends of the V-shaped piece are installed in the supporting bases respectively. A supporting column is arranged in the middle of the upper surface of the supporting pedestal. The upper end of the supporting column abuts against the forked root of the V-shaped piece. Rotary lifting columns are installed at the upper ends of the supporting bases respectively. Transversely-arranged clamping rods are installed at the upper ends of the rotary lifting columns. The ends of the clamping rods abut against the outer side faces of the arc-shaped plates. According to the special drilling tool for the V-shaped piece, the V-shaped piece is reversely installed on the supporting bases and the supporting column, the clamping rods are designed, in this way, the V-shaped piece is stably supported, drilling machining through a drill bit is greatly facilitated, the drilling efficiency is improved, and the qualified rate is increased.
