PRODUCTION OF CUTTING TOOL AND SO ON

PROBLEM TO BE SOLVED: To provide a method of producing cutting tool, etc., capable of increasing the rate of material yield of an expensive stock, shortening the time necessary for working, and improving quality. SOLUTION: A thin-walled resin mold (capsule), having a shape corresponding to the prescribed outside dimension, is previously prepared, filled, under vibration, with a metal or alloy powder having a composition of tool material, etc., evacuated, and hermetically sealed. The resultant capsule body in which the powder is hermetically sealed is subjected to CIP(cold isostatic pressing). After the capsule is removed from the capsule body, in which the powder is hermetically sealed, after CIP, the powder is heated and held in vacuum or in a reducing atmosphere and simultaneously subjected to brighttening treatment and subjected to sintering and HIP (hot isostatic pressing). After the excess metal of the member after sintering-HIP treatment is worked and removed, heat treatment is applied according to the material components of the tool material, etc., and further, finish grinding is performed.
