- composition ratio of a is larger than 0.59, the higher the chromium (Cr) element ratio, the more easily the hardness of the A layer 14 itself tends to decrease.
- composition ratio of b is less than 0.01, it is difficult to obtain the effect of improving the heat resistance by adding silicon (Si), and thus the composition ratio of b is less than 0.1. This is because it is difficult to manufacture the A layer 14 itself because it is too large.

This is because if the composition ratio of a is smaller than 0.15, the higher the aluminum (Al) element ratio, and in particular, when the aluminum (Al) element ratio exceeds 0.75, the hardness of the A layer 14 itself increases.
- composition ratio of a is larger than 0.60, the hardness of the A layer 14 itself tends to decrease as the chromium (Cr) element ratio increases.
- composition ratio of b is less than 0.01, it is difficult to obtain the effect of improving the heat resistance by adding silicon (Si), and thus the composition ratio of b is less than 0.1. This is because it is difficult to manufacture the A layer 14 itself because it is too large.
- the A layer 14 and the B layer 15 each have a thickness of 240 nm or less (particularly, 200 nm or less). It is preferable. This is because when the thicknesses of the A layer 14 and the B layer 15 are larger than 240 nm, the plastic deformability in the A layer 14 and the B layer 15 (single layer) is lowered, and the peel resistance obtained from the alternately laminated structure. This is because the chipping resistance tends to be low, which is not preferable.
- the A layer 14 and the B layer 15 each have a thickness of 150 nm or less (particularly, 100 nm or less). And preferred. This is because when the thicknesses of the A layer 14 and the B layer 15 are greater than 150 nm, the plastic deformability in the A layer 14 and the B layer 15 (single layer) is lowered, and the peel resistance obtained from the alternately laminated structure. This is because the chipping resistance tends to be low, which is not preferable.
- the A layer 14 and the B layer 15 have the same thickness. This is because if the thicknesses of the A layer 14 and the B layer 15 are different, the peelability between the A layer 14 and the B layer 15 tends to increase, which is not preferable.
- the upper layer 13 preferably has a thickness of 2 ⁇ m to 8 ⁇ m (particularly 3 ⁇ m to 6 ⁇ m). This is because if the thickness of the upper layer 13 exceeds 8 ⁇ m, the cutting edge part is liable to be peeled off or chipped under high-speed and high-feed cutting conditions, particularly in intermittent cutting, and the life is likely to be shortened. If the thickness of the upper layer 13 is less than 2 ⁇ m, the wear resistance of the upper layer 13 cannot be sufficiently exhibited, and it becomes difficult to ensure the cutting performance over a long period of time. .
- the base material 11 is preferably made of high-speed tool steel or cemented carbide. Because, when the base material 11 is made of high-speed tool steel or cemented carbide, it does not cause peeling or chipping of the lower layer 12 in the high-speed and high-feed cutting conditions, particularly in intermittent cutting, This is because it exhibits excellent wear resistance and can exhibit stable cutting performance over a long period of time.
- the cutting tool is not particularly limited as long as it is a tool for cutting, but it is very suitable if it is a gear cutting tool such as a hob or pinion cutter, or a broach
- the machine tool is not particularly limited as long as it is capable of cutting, but a gear cutter such as a hobbing machine or a gear shaper or a broaching machine is very suitable. is there.
