Abstract: PROBLEM TO BE SOLVED: To easily discharge chip by forming a continuous contact face on which a first cutting face having a positive rake angle is brought into contact with a cutting face formed on a center side more than this cutting face and having a negative rake angle continuously and smoothly. SOLUTION: When a metal saw is rotated at a high speed and a material to be cut S is cut by a cutting edge 3, chip T caused by it moves along a first cutting face 7 of a blade part 2, collides against a part of a continuous contact face 9 and a second cutting face 8 violently, and is sheared. That is the continuous contact face 9 and the second cutting face 8 have a function as a chip breaker. The chip T is curled into smaller pieces and is discharged to the outside due to centrifugal force. At this time, the chip T is not held in because a chip pocket 12 becomes large, and the chip T is smoothly discharged to the outside. For this reason, the discharge property of the chip T is improved by far when compared with a conventional method, and the cutting property is also improved.
