Improved structure of blade relief angle of single-blade drill point

The utility model provides an improved structure of a blade relief angle of a single-blade drill point. The single-blade drill point is provided with a drill body. One end of the drill body is connected with a drill handle for a machining machine to clamp. A silent point is formed in the tail end, f...

description	The utility model provides an improved structure of a blade relief angle of a single-blade drill point. The single-blade drill point is provided with a drill body. One end of the drill body is connected with a drill handle for a machining machine to clamp. A silent point is formed in the tail end, far away from the drill handle, of the drill body. The portion of the silent point extends in the inclined direction to form a cutting blade. The cutting blade is provided with a blade part. The side, close to the drill handle, of the blade part extends to form a first arc-shaped angle face, and the side, far away from the drill handle, of the blade part extends to form a second arc-shaped angle face. The relief angle is formed in the second angle face through a second cutting line of the blade part and a perpendicular line perpendicular to the drill body. The relief angle of the blade part is a fixed angle, and friction generated in the drilling process is reduced so that the phenomenon of breaking of the drill poi
