[0149] A second embodiment of the cutting tool according to the present invention will be described based on an example of a throwaway drill as a preferable example thereof. Image 6 It is a schematic side view showing the drill of this embodiment. Figure 7 is observed from the front Image 6 Brief front view of the drill bit. Figure 8 is used for illustration Image 6 Schematic diagram of the configuration of the outer edge and inner edge when the drill bit is cutting. also, Figure 8 In , the insert indicated by the dotted line shows the position when the insert indicated by the solid line is rotated by 180 degrees.
[0150] Such as Figure 6-8As shown, in the drill 21 of this embodiment, two throwing inserts (hereinafter simply referred to as inserts) 23 , which will be described later, are respectively attached to the front end portion of the tool body 22 whose center is the rotation axis O. One insert 23a is mounted with a screw 24 in such a manner that the inner edg...

[0176] A third embodiment of the cutting tool according to the present invention will be described based on an example of a throwaway drill as a preferable example thereof. The basic structure of the drill of this embodiment is the same as that of the drill and insert shown in the above-mentioned second embodiment.
[0177] Here, according to this embodiment, as Figure 12 As shown, it is covered with a coating layer 52 composed of nitride or carbonitride containing Ti and Al and having a layer thickness of 3-10 μm on the cutting edge, and when the tiny part of the coating layer 52 for the Cu-Kα line Diffraction intensities I(111), I(200), I(220), I(222), I(222) and I of the (111), (200), (220), (222), and (400) planes of the X-ray diffraction peaks The ratio I(220) / (I(111)+I(200)+I(220)+I(222)+I(400)) involved in (400) is q, rake face ( Figure 9 , 10 The q value of the upper surface 31) is q r , flank ( Figure 9 , 10 The q value of side 32) is q f ,Cutting edge( Fi...
