Abstract: A tool transfer device for machine tools that can reduce the tool transfer time and also reduce the cost of the device by eliminating the need for a driving source. The tool transfer device for machine tools has a tool magazine set beside a spindle on which a tool is mounted. The tool magazine serves for accommodating and holding therein a multiplicity of tools so that the tools are directed perpendicular to an axis of the spindle. A transfer pot is set on a spindle side of the tool magazine and is driven and moved by a horizontal moving unit and a vertical moving unit. This allows a next-process tool accommodated in the tool magazine to be taken out and transferred horizontally to a stroke end position by the transfer pot, and the next-process tool is then tilted at the stroke end position to a tool changing position in which the next-process tool is parallel to the axis of the spindle.
