The main problem that this prior art solved is that the deburring is got rid of in the time of the chamfer, and the structure is relatively complicated.
Prior art 2 provides an insert replaceable rotary cutting tool that reduces cutting resistance while maintaining the chipping resistance of a main cutting edge formed in a cutting insert, and is suitable for high-feed machining with high efficiency. A cutting insert having a polygonal flat or circular shape in plan view is detachably mounted on a main body of the rotary cutter with replaceable inserts. In the cutting insert, a chamfer edge and a rake face portion are provided on a rake face of a main cutting edge, and an R-shaped corner edge is formed at a corner portion. In addition, in the insert-replaceable rotary tool of this type, when the cutting insert is mounted on the rotary tool body, the main cutting edge of the cutting insert has the lowest point with respect to the rotational axis direction of the rotary tool body, and the width of the chamfer edge or the chamfer edge and the land portion is formed so as to gradually increase from the lowest point toward the outer peripheral side direction with respect to the rotational axis direction of the rotary tool body, thereby reducing the cutting resistance while maintaining the chipping resistance of the main cutting edge. The rotary cutter with replaceable blade mainly solves the problems of reducing cutting resistance while preventing the main cutting edge from breaking, and has complex structure and overhigh processing cost
