Abstract

PURPOSE: To braze a cutting edge tip stably on a support member by carrying out the brazing through a sintered hard alloy base on which a polycrystal sintered body is formed under superhigh pressure and high temperature at its central concavity.
CONSTITUTION: A polycrystal sintered body 3 is formed on a sintered hard alloy base plate 1 at its central concavity 18, which is divided into four, and a cutting edge tip 17 is formed by grinding an arched wall portion 16 to a plane. The portion 16 is left existent partly. A cutting tool shank 19 of steel make has a notched step 20 formed thereon, and said cutting edge tip 17 is brazed in the notched step. A stable brazing is obtainable through plane brazing of sintered hard alloy with steel.
