PROBLEM TO BE SOLVED: To secure stable cutting while an execution cost is made moderate. SOLUTION: A cutter main body 14 and a pressing means 16 for supporting, in a freely approachable, separable and transferrable manner, that are provided. The main body 14 is equipped with the first - the fourth guide sieves 18a-18d, a main sieve 20, a rotary driver 22 for the main sieve 20 and a frame 24. For the main sieve 20 installed adjoining to a rear side of the guide sieves 18a-18d is provided so that a rotary surface conforms to the rotary surface of the guide sieves 18a-18d. When a cutting objective 10 is cut, a guide hole 34 is bored on the cutting objective 10, and the guide sieves 18a and 18c are inserted into the guide hole 34 while the rotary driver 22 is rotated. Then, when a feed handle 32 is rotated, and the cutter main body 14 is moved to approach the cutting objective 10 side, a wire saw 12 is pressed in contact with the cutting objective 10 existing in the guide hole 34 to cut by friction this part. |
