This paper deals with design of milling tool for milling of shaped groove. Actual industry production requires the large amount of tools and notably the special tools used for example when shaped milling. The requirements on the quality of tools are increasingly demanding. The quality of tools is given by construction, production process, selected material and also heat treatment. Shaped milling requires special tools made for given shape. Main request on the construction of tool is making of shape of cutting edge, which can produce the required shape of workpiece.
