A tool turret shortening the distance between an acting point and a fixed point is provided to shorten a clamp point clamping a disc so that the disc cannot be moved and an acting point where a cutting machining operation is performed by a tool. A tool turret is mounted to a machine tool to be used. The tool turret includes a motor(1), a rotary tool drive section, and a tool exchange drive section. The motor generates power for driving the rotary tool and power for exchanging the tool. The rotary tool drive section includes a pulley(3), a timing belt(4), an air cylinder(7), a shaft(12), and a tool drive shaft(17). The tool exchange drive section includes a gear shaft(14), a pivot curvic coupling(21), a fixed curvic coupling(20), and a piston curvic coupling(22). The tool turret shortens the distance between an acting point and a fixed point by using the curvic couplings.
