The present invention discloses a drilling method and auxiliary drilling tool for a part with evenly distributed oblique through holes on multiple surfaces. The drilling method comprises: using the auxiliary drilling tool for the part with evenly distributed oblique through holes on multiple surfaces to quickly transpose the part on an oblique block and drill the oblique through holes on multiple surfaces. Because the force generated by the mating section and the pressing through hole is greater than the force generated by the diamond through hole and the diamond section, during transposition, the drilling template, part, and positioning column are quickly pulled out of the diamond through hole of the oblique block by prying the oblique surface, and then slid and disassembled for transposition. This solves the problem of requiring slow rotation to release the threaded connection and reversing, which prevents the part from quickly transposing and drilling on the oblique surface base. The oblique through holes on the next surface of the part are then drilled, thereby improving the processing efficiency of the part.
