Walter recommended its new reinforced parting blades from the G2042 series of the Walter Cut System provided with a dual internal coolant supply which accurately targets the flank face and rake face. The new Walter Cut G2042 offers a constant optimum operating temperature and chip control. Regardless of how deeply the parting blade penetrates the workpiece, tool life and process reliability remain at the highest level. This type of cooling also ensures that the lubricating film does not tear off, which creates end faces with a very high surface finish quality. The G2042 parting blades with precision cooling are suitable for cutting depths of up to 33 mm.
