Indexable insert e.g. throwaway tip, for cutting tool, has first minor cutting edge and second minor cutting edge connected at connection point between arc of first minor cutting edge and arc of second minor cutting edge

摘要

A first minor cutting edge (21) and a second minor cutting edge (22) are connected at a connection point (P1,P2) between the arc of the first minor cutting edge and the arc of the second minor cutting edge to obtain a small intersection tangent angle of 1 degree or less. An independent claim is also included for a cutting tool.
