These versatile device for metalworkers is providing ideal conditions for core drilling, tapping, countersinking and spiral drilling – for example in metal working companies and on construction sites. The motor is equipped with soft start, solid shaft electronics and overload protection. Thanks to the electromagnet with a holding force of 16 000 N, you are drilling extremely precisely and safely. Soft-touch handles and the infinitely adjustable carriage make working with the RB 50 B RL-E uncomplicated and pleasant, as does the self-explanatory operation. Our Robust one with the Twist can be combined with core drills up to a diameter of 50 mm, with step drills up to a diameter of 40 mm and with spiral drills up to a diameter of 20 mm.
