Chip disposal is one of problems in semi dry cutting because the amount of using oil is very little. Therefore new cutting method that is able to collect chips through the center hole of tool immediately was proposed to solve this problem. In this study, machining test of a molding die using withdrawal of chips by suction was carried out with developed ball-end mill. As a result, it was confirmed that chips are not scattered in the machine tool. In addition, it was found that this cutting method has a comparatively high lubrication effect.
