Document Type and Number:
WIPO Patent Application WO/2023/090246
Kind Code:
A1
Abstract:
The present invention increases the durability of a base portion to set a cutting condition with a large feeding amount. A first end face of the base portion comprises, when seen from the tip-end side in a direction along a rotational axis: a first region positioned rearwardly in a rotational direction and radially outside with respect to a second rear face of a cutting portion; and a second region positioned rearwardly in the rotational direction with respect to a second front face of the cutting portion and radially inside of the first region. When a virtual plane including the second rear face is a reference surface, the first region includes a first portion in which the width of a region sandwiched between the reference surface and a first rear face of the base portion gradually increases radially outward, and the second region includes a second portion in which the width of a region sandwiched between the reference surface and the first rear face gradually increases radially inward.
