CEGIELSKI GRV 553 radial drilling machine

CEGIELSKI GRV 553 radial drilling machine was built in Poland. The machine used for reaming, countersinking and threading holes in workpieces made of e.g. steel and cast iron, offers a wide range of revolutions and feeds for any machining operation. It is equipped with a reliable spindle with Morse 5 taper rotating from 12.5 to 1600 times per minute. The total weight of the machine is 6050 kg.
