Drill Description

Curtain up for the XXL model from our core drilling machine basic line with right/left run. The RB 100 B RL-E is the perfect device for tasks involving large drilling diameters! The numbers speak for themselves: 245 mm stroke, 116 mm height adjustment, 4-speed gearbox. With a holding force of 20 000 N, the electromagnet is ensuring that the core drilling machine is adhering securely to the material. For its wide range of applications, it can be combined with core drills with a diameter of up to 100 mm, with step drills with a diameter of up to 55 mm and with spiral drills with a diameter of up to 32 mm. The RB 100 B RL-E is just as powerful in thread cutting as it is in drilling. With a tap you can cut threads for screws up to M50 (using a tapping attachment or tapping chuck). To protect the machine from overload, a slip clutch is limiting the torque. Besides the 'hard facts' ALFRA always focuses on user-friendliness. Soft-touch handles and a practical membrane keyboard make the daily use of the machine pleasant and safe.
