Abstract:
Provided is a cutting tool that simultaneously improves both fracture resistance and wear resistance. The cutting tool according to the present invention has an end surface, a peripheral side surface intersecting with the end surface, and a cutting edge in an intersecting ridge part along the end surface and the peripheral side surface, and when first and second points A and B are defined on the cutting edge, the first point A protrudes further toward an outer side of the cutting tool than the second point B. The cutting edge has a honing surface. The honing surface has a portion, the width of which gradually increases from the first point A toward the second point B.

Claim (Index 7):
A cutting insert, comprising:\n an upper surface on which a rake surface is formed; a first side surface which connects to the upper surface and on which a flank is formed; a second side surface which connects to the upper surface and the first side surface; a third side surface which connects to the upper surface and the second side surface; a fourth side surface which connects to the upper surface, the first side surface, and the third side surface; a lower surface which connects to the first side surface, the second side surface, the third side surface, and the fourth side surface; and a cutting edge which is formed in a connecting part between the upper surface and the first side surface and which has a honing surface, wherein a hole penetrating the second side surface and the fourth side surface is formed, the cutting insert performs a cutting-off process in a state where the cutting insert is fixed to a holder by bringing a part of the fourth side surface into contact with the holder by using a male screw inserted into the hole and, at the same time, bringing at least respective parts of the upper surface and the lower surface into contact with the holder, the cutting edge is formed such that: in a top view from a direction opposing the upper surface, the cutting edge is inclined with respect to the second side surface and the fourth side surface so that a distance from the cutting edge to a central axis of the hole increases gradually toward the fourth side surface from the second side surface; and in the top view, a width of the honing surface gradually increases toward a second point, which is closer to the second side surface than to the fourth side surface on the cutting edge, from a first point which is closer to the fourth side surface than to the second side surface on the cutting edge.
