の取付孔である。In these drawings, a throwaway chip (hereinafter referred to as a chip) A has a shape of an unequal-angled hexagonal plate, and has three acute-angled corners 1 and three acute-angled corners at the outer peripheral corners of its upper and lower surfaces. 2 are formed. A straight cutting edge 3 is formed between the corners 1 and 2, and an annular chip breaker 4 is formed inside the cutting edge 3 and the corners 1 and 2. A ring-shaped seating surface 5 is formed inside the chip breaker 4 along the chip breaker 4. Reference numeral 6 is a mounting hole for mounting the chip A on a chip mounting seat of a tool such as a chip holder using mounting screws.

周縁部に近付けるとよい。By the way, generally, in order to increase the clamp rigidity of the chip with respect to the chip mounting seat of a tool such as a chip holder, the area of the seating surface of the chip is widened so that the contact area with the chip mounting seat is widened and the seating surface is centered on the chip. It is advisable to bring it close to the peripheral portion farthest from.

け着座面５がチツプＡの周縁部から離れてしまい、この
結果、クランプ剛性が低くなるという欠点があった。However, in the chip A having the above-described structure, the chip breaker 4 is formed inside the cutting edge 3 and the corners 1 and 2 so as to form an annular shape over the entire circumference of the chip. There is a drawback in that the clamp rigidity is lowered as a result of being separated from the peripheral portion of A.

クランプ剛性が高くなるという利点がある。Therefore, a chip which eliminates such drawbacks is shown in FIGS. 5 and 6. The chip B shown in these drawings does not divide the annular chip breaker 4 from the corner of the seating surface 5 toward the corner 1 in the portion farthest from the center of the chip B, that is, near the corner 1 having an acute angle. To extend
In addition, the seating surface 7 is formed in a peninsular shape that is flush with the seating surface 5. In such a chip B, the seating surface 7 is formed in the peripheral edge portion farthest from the center of the chip B, that is, in the vicinity of the three corners 1, and the contact area with the mounting seat of the tool is the same as that of the seating surface 7. Since the width becomes wider, there is an advantage that the clamp rigidity of the chip becomes higher.

鋭角のコーナ１とされている。Each obtuse-angled corner 2 formed on each outer peripheral edge of the upper and lower surfaces of the chip 10 and the cutting edges 3 and 3 adjacent to the corner 2.
Inside, a chip breaker 11 is formed by notching the upper and lower surfaces of the chip 10 in a substantially V shape, and is formed with a slight gap between the ends of the chip breakers that are adjacent to each other. Both ends of each chip breaker 11 are located slightly on the corner 2 side from the joint between the acute-angled corner 1 and the cutting edge 3, and the flat surface near each acute-angled corner 1 is the corner seating surface 12. . The corner seating surface 12 is flush with the seating surface 5, and the ridge line portion of the corner seating surface 12 is an acute-angled corner 1.
