The invention discloses a novel drill which comprises a drill handle, a drill neck, a drill point and a chamfer. The drill handle is of a cylinder structure, one end of the drill handle is connected with the chamfer, and the other end of the chamfer is connected with the drill neck; the other end of the drill neck is connected with the drill point; a spiral chip discharging groove is formed in the drill neck; the drill point is provided with two cutting edges, and the two cutting edges are spirally arranged with the central axis of the drill handle as the center; the chamfer is located between the drill neck and the drill handle, emery particles are evenly distributed on the surface of the drill neck, the surface of the drill point and the surface of the chamfer, and the central axis of the drill handle, the central axis of the drill neck, the central axis of the drill point and the central axis of the chamfer are located on the same straight line. In this way, the novel drill is simple in structure; the chamfer device is added on the basis of a common drill, and a hole surface is chamfered while drilling is completed; the emery particles are arranged on the surface of the drill point, the surface of the drill neck and the surface of the chamfer of the drill, and emery is high in hardness, so that abrasion of the drill is effectively avoided, oxidation resistance is good, and the drill is not deformed at a high temperature; it can be guaranteed that the inner wall of a drilled hole is high in smooth finish and emery marks are few and shallow, the chamfer is reamed flat, functions are diversified, and practicability is high.
