Abstract
A parting tool for the chip removing machining of metal blanks includes a blade and a replaceable cutting insert mounted in a seat, which is delimited between a bottom support and an elastically resilient clamping finger. The cutting insert includes an upper side, in which there is included a front rake surface, as well as an application surface positioned behind the same and against which the clamping finger is pressed. In the clamping finger, a flushing channel is included to spray a cooling medium toward the rake surface. A front nose of the clamping finger facing a shoulder is formed between the rake surface and the application surface and has the purpose of protecting the nose from chips. The shoulder has two knobs mutually separated by a central notch, via which cooling medium can pass from the flushing channel toward the rake surface.
