Abstract

A parting tool is provided having a tool shank and an interchangeable blade support connected thereto. The blade support is equipped with a blade attachment of blade. The blade support makes contact along one side thereof with a broad-side of the tool shank. The blade support has narrow sides which are guided, at least on sections, by two guide surfaces of the tool shank typically disposed on flanges. Flat contact surfaces on said flanges perpendicularly disposed in relation to the broad side of the tool shank butt against two corresponding counter guide surfaces on said blade support and are pressed against each other by clamping means such as longitudinally off-set screws. In comparison with earlier parting tools used for the same applications, the parting tools of the invention can be made smaller in overall height and provide extremely stable connection between the blade support and the tool shank, thereby greatly reducing rattling and vibrations during normal cutting operations.
