Drill Description

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 up to a diameter of 50 mm, with step drills up to a diameter of 40 mm, and with twist drills up to a diameter of 20 mm. 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.
