A blade for a blade fastening device is provided with a body (10) having a first end fastened in a blade seat (60) and a second end extending out of the blade seat (60); a machining point (20) formed at the second end of the body (10) for machining an object being machined; and at least one cutting fluid groove (30) formed on a surface of the body (10) and extending from the second end of the body (10) to the machining point (20). The blade can guide cutting fluid to an object being machined via the at least one groove (30) so as to clear swarf left at a cutting site and decrease temperature at the cutting site. Further, the structural strength of the blade can be maintained. |
