Segment grinding head with rotating edge segment. This makes it possible to edit surface transitions wall/wall and wall/ceiling. Connection option for the Flex safety vacuum cleaners with volume flow optimization on the guide tube with the Flex clip system, The high-performance turbine ensures high suction power and high negative pressure. This creates an excellent extraction result Start-up delay avoids voltage peaks when starting and switch-off delay (15 seconds overrun) empties any dust residue in the suction hose Separate engine air cooling duct with coarse dirt filter. Protects the turbine from the supply of ambient air and thus increases its service life. (Pale dust filter PES available as accessory) For extraction work, the focus is on smaller power tools such as orbital sanders.
