Drill Description

Metal core drilling on materials from only 3 mm thickness - this is a unique selling point of our SP line. The basis: The patented permanent magnet with TiN coating is adhering horizontally and vertically, independent from power supply and even on thin-walled ferromagnetic materials. 'Crashes' in case of a power failure are therefore impossible. Further features for the protection of man and machine include: the sensor function for checking the magnetic holding force, soft start and overload protection. Furthermore, the RB 50, like all models from our SP line, is extremely user-friendly. For example by soft-touch handles and the clearly arranged foil keyboard. Use the RB 80 SP with core drills up to a diameter of 80 mm, with twist drills up to a diameter of 32 mm and with step drills up to a diameter of 55 mm
