摘要:
A production method for an insertion end, especially for an insertion end of a drilling, chiseling or boring tool, including the following steps: a longitudinal groove is formed in the outer surface of a preferably cylindrical end piece of a blank, whereby the longitudinal groove acquires an open end section on a front face of the end piece. The outer surface of the end piece is surrounded by a die tool that engages into the longitudinal groove outside of its open end section. The open end section is closed in that the surrounded end piece is compressed by means of a stamp acting on the front face. The segmented, multi-component die tool preferably lies flush against the outer surface of the end piece outside of the longitudinal grooves.
