ALFRA Rotabest® – RB 50 SP

Metal core drilling in any position? No problem with our ALFRA ROTABEST RB 50 SP! The basis: The patented permanent magnet with tin coating adheres horizontally and vertically, regardless of the power supply, from a material thickness of just 3 mm. This prevents ‘crashes’ in the event of a power failure.

Our premium series also impresses with the sensor function for checking the magnetic adhesive force - for maximum work safety. The infinitely adjustable carriage, soft start, overload protection and soft-touch handles are just some of the advantages you will benefit from.

At 11.5 kg, the RB 50 SP is far lighter than competitor products with a similar performance profile. The RB 50 SP is suitable for use with core drills up to 50 mm in diameter with twist drills up to 20 mm and with step drills up to 40 mm in diameter.
