Abstract

PURPOSE: To obtain a boring reamer of rich durability at low price by using partially an expensive high hard material.
CONSTITUTION: An edge part 1 to perform a cutting work is installed at the point of a handle part 2. The edge part 1 is formed taking a cemented carbide having an excellent resistance to wear as a base metal and is formed with a plural lines of edges 1a and at the same time, super left twisting right edge twisting angle is formed and the twisting angle is made to the left approximately 50W70° and at the front part, a starting taper angle of approximately 20° or less is formed and further, at the rear part, a guide edge 3 is installed. Further, a high hard piece 6 is formed with a high hard material sintered with a super high pressure having a hardness harder than the cemented carbide constituting the edge part 1 and this piece 6 is buried in a part of the edge part 1 having an external face exposed and it is fixed so that it can not be removed.
