ALFRA Rotabest® – RB 80 B

The models of our X-series have been designed to improve your work processes significantly. This is why the RB 80X is combining all the performance features of metal core drilling with ergonomically perfect operating comfort and well thought-out equipment. The LED sensor is ensuring safety at a glance. It is indicating, if the material has the required thickness for reliable magnetic holding force. In addition, the slip clutch is protecting the machine from overload by limiting the torque. The same applies to the 'motor emergency stop' function. You drill safely and precisely - for example, with core drills with a diameter of up to 80 mm, with step drills up to a diameter of 55 mm and with twist drills up to a diameter of 32 mm. The RB 50 X has an MK3 holder and a continuously adjustable carriage with self-adjusting guide. The user-friendly extras: the practical membrane keyboard, soft-touch handles, a holder for hexagon keys and a cable in the convenient length of 5 meters.
