A cutting device of a self-centering cutter holder is disclosed. The cutting device includes a cutter holder with a main body and a base body. A cutter mounting part and an extension handle part are separately arranged at upper and lower parts of the main body; the extension handle part is at least partially connected to a pressing surface at the lower side of the main body and is provided with a supporting surface and a central axis, around which a surface plain line of the supporting surface forms an angle. The cutter holder is mounted in a containing part of the base body through the extension handle part, and can independently generate fastening force to fix the cutter holder and the base body together, so that the whole cutting device is greatly improved in reliability and is greatly prolonged in service life, and the production cost is reduced.
