After the tool rest of a machine tool is moved up, the boring bar 3 is moved down by the descent of a piston 10 while the bar 3 is guided by the bushing 17 of a holder 1 for the bar 3. A pin 5 is thus removed out of the groove 15b of a ring 15. The shaft 14 is moved rightward by the action of a piston unit 13 to turn a gear 7 to rotate the boring bar 3 by 90°. The machined diameter D 2  of the workpiece 4a is made equal to 2√R 2 +E 2  by the rotation. The piston 10 is moved up to fit the pin 5 in a ring groove 15a and secure the boring bar 3 on the holder 1 to machine the workpiece to set the diameter D 2 .
