INSERT DETACHABLE CUTTER AND CUTTING INSERT

摘要

PROBLEM TO BE SOLVED: To enable highly efficient cut processing by increasing the number of cutting inserts mountable to a cutter body specifically in a longitudinal blade type insert detachable cutter used in cut processing of a casting to be cut. SOLUTION: In adjacent insert mounting seatings 13 in a circumferential direction of a plurality of the insert mounting seatings 13 formed at the outer circumference of the tip of the cutter body 11 rotated around an axis O, the bottom faces 15 of the mounting seatings directed to the outer circumferential side of the cutter body 11 of the insert mounting seatings 13 on a rear side in a cutter rotational direction T are extended to the cutter rotational direction T side and are made to cross the wall faces 16 of the mounting seatings positioned at the rear side in the cutter rotational direction T of the insert mounting seatings 13 on the cutter rotational direction T side and directed to the cutter rotational direction T at an acute angle.
