Claims

[Scope of utility model registration request]

A support seat surface 8 corresponding to the planar shape of the chip with a fixing screw hole 7 penetrated through the center is formed on the chip support portion 6 of the cutting tool, and the side surface of the chip 3 is brought into contact with the peripheral edge of the support seat surface 8. The holder 1 has contact walls 9a and 9b formed adjacent to each other to prevent movement in the lateral direction. A fixing screw 2 having an eccentric pin 13 protruding from a slightly eccentric position, and a chip 3 having a shape corresponding to the support seat surface 8 and having a pin hole 15 through which the eccentric pin 13 is inserted. The fixing screw 2 is screwed and inserted into the fixing screw hole 7 to make the eccentric pin 13 protrude from the support seat surface 8, and the chip 3 is supported so that the pin hole 15 is inserted into the protruded eccentric pin 13. After placing it on the seat surface 8, turn the fixing screw 2 and attach the eccentric pin 13.
A tip fixing structure for a cutting tool, characterized in that two adjacent side surfaces of the tip 3 are pressed against corresponding cutting wall surfaces 9a and 9b.
