摘要： The invention relates to a simple shaft tool than can be produced in an easy and economical manner. Said tool comprises fixedly disposed winglike inserts for milling-type machining of non-chip forming materials and remains operational during unavoidable abrasive wear and increased wear and tear. According to the invention, the shaft tool is characterized by a shaft (1) that can rotate around its longitudinal axis (2). Said tool can be releasably connected to a drive device and is fitted with at least one groove-like recess (7) extending in axial direction and a flat cutting blade (8) on the free end segment (6) of the tool, said blade being provided on the front side with a non-cutting edge (12) when viewed from the direction of displacement (9). The shaft tool is used in the production of molds, more particularly heat-resistant casting molds for manufacturing of cast parts made of metal.
