A tool changer for interchanging tools between a machine tool and a magazine in a minimum amount of time so as to reduce the down time of a machine tool. The tool changer includes a frame or base member for mounting on the machine tool with the frame member presenting at least two spaced apart mounting planes. Two tool change arm members are rotatably mounted on the frame and in the spaced apart mounting planes. A drive mechanism affords a reciprocating rotatable motion as well as a linear motion of each arm member so as to effect a motion similar to a fourbar linkage and a parabolic motion to the arm members. Each arm member has a clamping portion to grip tools in a firm but releasable manner. In a preferred manner, the arms are rotated through an arc of 180 DEG and the clamping members are positioned 90 DEG out of phase from each other. Also preferably the mounting planes are positioned at an angle of 45 DEG with respect to each other with the base portion providing the mounting planes in the form of a truncated triangle.
