Is formed by a predetermined length by inclining by an angle β substantially corresponding to the axial rake angle β 1 with respect to an imaginary line X orthogonal to the main cutting edge 4, and its width dimension is on the flank 2 It is formed so as to be equal from the blade 4 to the terminal portion 12 and gradually narrow in the depth direction. Therefore, as shown in FIG. 10, even if the tool body is attached with the axial rake angle β 1 , the ridge line concave portion 7 having a small radius of rotation and the groove portion 1 having a larger radius of rotation are provided.
The edge portion 18 of No. 1 is not located on the same circumference in the rotation locus. As a result, there is no possibility that abnormal friction will occur at the edge portion 18 and chatter will occur, or that the main cutting edge 4 will be chipped or chipped. Therefore, according to this tip 10, not only the cutting resistance reduction effect due to the cutting of the chips of the groove portion 11 but also the improvement of the chip discharging property by providing the axial rake angle β 1 and the cutting effect of the main cutting edge 4 are achieved. Preventing chattering due to impact relaxation and further reducing cutting resistance, the groove 11 and the axial rake angle β
It is possible to obtain a synergistic effect with 1 .

層顕著に発揮される。Moreover, since the width of the groove portion 11 is made equal on the flank surface 2 from the main cutting edge 4 to the terminal end portion 12, the area where the flank surface 2 is cut by the groove portion 11 is the same as the groove portion 11 side. The width is smaller than that in the case where the width is wide. The area of the flank 2 is kept substantially constant regardless of the size of the inclination angle β of the groove portion 11 because the groove width is constant. Therefore, the tip mounting seat 16 of the tool body 15
Even when the chip 10 is mounted by bringing one of the flanks 2 into contact with each other, the contact area between the chip mounting seat 16 and the flank 2 is sufficiently secured, and the mounting rigidity of the chip 10 is maintained high,
The inclination angle β of the groove portion 11 can be made sufficiently large to increase the axial rake angle β 1 of the main cutting edge 4, whereby the effects of preventing chattering and reducing cutting resistance can be more remarkably exhibited. It

It does not become smaller than ± β, and the groove 1
It is possible to secure a large intersection angle as compared with the case where 1 is formed so as to be wider on the terminal end 12 side. Therefore, according to the tip 10 of the present embodiment, the strength of the tip at the peripheral edge of the opening of the groove 11 on the side of the main cutting edge 4 can be maintained, and the ridge line between the side wall of the groove 11 and the rake face 3 may be broken. It is possible to prevent the occurrence of chipping, and it is possible to prevent the occurrence of chipping or chipping of the main cutting edge 4 due to such chipping.

The actual intersection angle (intersection angle in the cross section perpendicular to the ridge portion) formed by both side walls of No. 1 and the rake face 3 becomes larger than that when viewed from the flank face 2 side. Therefore, with this tip 10, it becomes possible to secure a higher tip strength around the main cutting edge 4, and in combination with the above-described effect of preventing abnormal friction, it is possible to more reliably prevent chipping and chipping.

It may have a semicircular cross section like the groove 20 shown in FIG. 1 or a substantially trapezoidal cross section like the groove 21 shown in FIG.

である。[Effects of the Invention] As described above, in the tip of the present invention, the main cutting edge is formed on the ridge portion where the flank and the rake face intersect, and the main cutting edge is divided into one or more sections on the flank. The groove portion of the chip in which the groove portion is formed extends in a direction inclined with respect to an imaginary line orthogonal to the main cutting edge and has its end portion on the flank, and its width dimension is on the flank surface. It is formed so as to be equal from the main cutting edge to the terminal end, and its cross-sectional shape is gradually narrowed in the depth direction from above the flank.

Absent. Therefore, in addition to the effect of reducing the cutting resistance due to the cutting of chips in the groove portion, in addition to the effect of improving the chip discharging property obtained by adding an axial rake angle and the occurrence of chatter due to the impact relaxation during cutting of the main cutting edge. At the same time, it is possible to obtain the effect of prevention and further reduction of cutting resistance.

一層顕著に発揮される。Moreover, since the width of the groove is equal on the flank from the main cutting edge to the terminal end, the area where the flank is cut by the groove is formed so that the groove becomes wider on the terminal end side. It will be smaller than the case. The area of this flank is kept substantially constant regardless of the inclination angle of the groove. Therefore, even when one of the tool main body and the chip mounting seat is brought into contact with the chip to mount the chip, the contact area with the chip mounting seat is sufficiently secured to maintain the mounting rigidity of the chip high and the inclination of the groove portion is maintained. By making the corner sufficiently large, the axial rake angle of the main cutting edge can be increased, whereby the effects of preventing chattering and reducing cutting resistance can be more remarkably exhibited.

Since the groove width can be increased and the groove width is gradually narrowed in the depth direction, the actual intersection angle is further increased. Therefore, according to the tip of the present invention, a high tip strength can be secured around the main cutting edge, and in combination with the effect of preventing abnormal wear described above, chipping and chipping can be more reliably prevented.
