CUTTING TOOL FOR METAL WORKING AND METHOD FOR PRODUCING IT

摘要

According to the invention, there is provided a cutting tool and a method in the production of a cutting tool for metalworking that results in a holder body having increased fatigue strength at loads over 60 % of the yield point in tension. The method and the tool are characterized in that the holder body of the tool is subjected to a hardening process resulting in deep hardening, and that the holder body then is subjected to a surface treatment resulting in a strain hardening of the surface in order to introduce compressive stresses in the surface zone of the holder body.
