Abstract

PURPOSE:To perform axial high speed cutting with excellent machining precision, by a method wherein a projected part is formed on either of the seating surface of a tip and a tip mounting seat with which the seating surface makes contact, and a recessed part engaged with the projected part is formed in the other. CONSTITUTION:A circular recessed part 20 having size larger than that of a hole part 10 is formed in a part where a mounting hole part 10 of the seating surface of a tip 4 is opened, and a columnar projected part 21 engaged with the recessed part 20 is formed in the portion, facing the recessed part 20, of a bottom surface 14 of a tip mounting seat 3. Through engagement of the projected part 21 with the recessed part 20, the tip 4 is secured in the tip mounting seat 3 of an end mill body 1 by means of a mounting bolt 12. Thus, even when a high load is axially exerted during cutting, since movement of the tip 4 on the tip mounting seat 3 is reliably blocked, even when axial feed cutting at a high speed is performed, cutting precision is prevented from lowering.
