The invention relates to an internal fixation plate and a machining tool and process thereof, and belongs to the field of medical instruments. The internal fixation plate sequentially comprises a main plate, a buckling plate and a hook plate, wherein the opposite end surfaces, located in the thickness direction, of the main plate are an operation surface and a contact surface respectively, the opposite side surfaces, located in the width direction, of the main plate are threading surfaces, a plurality of threading holes are formed in the main plate, and the threading holes are formed from the operation surface to one of the threading surfaces. According to the invention, through inclined arrangement of threading holes, the feeding depth of a drilling tool during machining of the threading holes is reduced, so that the vibration amplitude of the drilling tool caused by large drilling depth is reduced, the state stability of the drilling tool during working is improved, and the effects of reducing vibration and
