Abstract

The invention relates to a chip removing machining cutter, a cutting board clamping blades and a replaceable blade, and provides a cutter for chip removing machining of metal blanks. The tool comprises a cutting board and a replaceable cutting blade mounted in a seat, which is delimited between a bottom support and an elastically resilient clamping finger. The cutting blade includes an upper side, in which there is included a front rake surface as well as an application surface, which is 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, which is formed between the rake surface and the application surface and has the purpose of protecting the nose from chips. According to the invention, said shoulder consists of two knobs, which are mutually separated by a central notch, via which cooling medium can pass from the flushing channel toward the rake surface.
