The models of the Alfra Basic-Line are reliable and robust helpers, for example in your company or on your construction site. Your advantage: You benefit from an excellent price-performance. Concretely this means: Thanks to a great performance for less money you stay economically flexible. In addition, like all models of the basic line, our RB 50 B is a real endurance runner: no matter how many hours a device from the basic line is in operation for you - you can look forward to long service lives. Our robust machine can be combined with core drills, with step drills, and with twist drills. It is equipped with an MK2 holder with coolant ring and a continuously adjustable carriage with self-adjusting guide. The RB 50 B is particularly user-friendly due to its soft-touch handles, an ergonomic control keyboard and a comfortable 5m cable.
