ALFRA Rotabest® – RB 80 B RL-E

Our Basic Line models with right/left rotation function combine all the performance features of efficient metal core drilling with ease of use and additional application options. Metalworkers will soon no longer want to do without the RB 80 B RLE as the perfect tool for core drilling, tapping, countersinking and twist drilling.

The high-performance tool can be combined with core drills up to a diameter of 80 mm, with step drills up to a diameter of 55 mm and with twist drills with a diameter of up to 32 mm.

You can use taps to cut threads for screws up to M30 (using a tapping attachment). We recommend the use of a tapping chuck for screws up to M30.
