Abstract
The utility model discloses a novel square combined type file which comprises a file body and a file handle. The cross section of the file body is of a square shape. First filing lines, second filing lines, third filing lines and fourth filing lines are arranged on the four side faces of the file body respectively. The first filing lines and the third filing lines are single-tooth ripples, the tooth pitch of the first filing lines is 1.5-2.1mm, and the tooth pitch of the third filing lines is 0.5-0.8mm. The second filing lines and the fourth filing lines are double-tooth ripples, the tooth pitch of the second filing lines is 0.21-0.32mm, and the tooth pitch of the fourth filing lines is 0.17-0.2mm. By the aid of the mode, the novel square combined type file has various filing lines, and thus the novel square combined type file can meet the requirement for different filing precisions.
