Abstract

This head replaceable cutting tool comprises: a shaft-like tool body (1) which is rotated around an axis line (O) in a tool rotation direction (T); and a cutting head (11) provided with a cutting edge (12) and detachably attached to a front end of the tool body (1). The tool body (1) and the cutting head (11) are attached to each other with a body-side abutting surface (5) on a front end surface of the tool body (1) abutting against and closely attached to a head-side abutting surface (17) on a rear end surface of the cutting head (11). A recess (16) and a protrusion (4) insertable into the recess (16) are formed on the rear end surface of the cutting head (11) and the front end surface of the tool body (1), respectively. The recess (16) and the protrusion (4) are formed to become wider in a circumferential direction toward a radially outer peripheral side with respect to the axis line (O).

Description

Technical field [0001] The present invention relates to a head replacement cutting tool capable of disassembling a cutting edge of a cutting edge in the head replacement cutting tool at the front end portion of a shaft-shaped tool body rotating in the rotation direction of the tool rotation in the tool rotation in the tool. The cutting head that is capable of detachably mounted on the front end, and the cutting head in the head replacement cutting tool can be disassemblely mounted on the front end portion, rotating around the axis along the axis of the tool rotates in the direction of the tool. [0002] The present application requires priority to the provision of Japanese Patent Application No. 2019-147893, requested in Japanese August 2019. Background technique [0003] As such a head replacement cutting tool, for example, in Patent Document 1, the following is described: by holding the mounting screw and setting in the screw insertion hole provided on the axial center of the r...
