The presented article is focused on the abrasive water jet machining of tool steel material. Selected tool steels Uddeholm Dievar and Böhler K110 were machined and final pockets were evaluated based on the side angle of the pocket. Sequentially were created pockets with increasing depth from 1 to 5 mm for both materials. Evaluation of pocket angle is crucial factor for determination of machining allowance for finishing cuts. Also metallography analysis for both materials was created for observation of removal process and for detection of cracks produced during abrasive water jet machining. In terms of corrosion of presented tool steels can be stated that due to higher number of alloying elements is corrosion on machined surface acceptable for further processing of created shapes. Obtained results can extend application possibilities of AWJ milling for rough machining of tool steels, especially for thin-walled components with reduction of induced residual stresses and deformations of shapes.
