Robust meets versatile - our devices, belonging to the Alfra basic line with right/left run function are combining all performance features of efficient metal core drilling with user friendlyness and additional application possibilities. Metalworkers will soon no longer want to do without the RB 80 B RLE as a perfect tool for core drilling, tapping, countersinking and spiral drilling. This high-performance device can be combined with core drills, with step drills and with twist drills. With a tap you can cut threads for screws up to M30 (using a thread cutting device). We recommend using a tapping chuck for screws up to M 30. The RB 80 B RLE is based on the principle 'everything at a glance'. The clear operating concept is virtually self-explanatory. Mistakes or application errors are almost impossible.
