Compact metal edge milling machine for 45° chamfers and radii of 2 to 3 mm on visible edges. Oxide and burr-free surfaces provide optimal preparation for the application of powder or paint coatings for maximum corrosion protection. The one-touch controller features patented, tool-free milling depth adjustment in 0.1 mm increments, with detent points for short setting times to prevent unintentional adjustment of the milling depth while working. The slim milling head includes standard carbide inserts and a ball bearing thrust ring for working in pipes and on curves. A guide stop ensures an even work result and high surface quality when working on straight sheets. The Metabo Marathon motor has patented dust protection for long service life. Vario-Constamatic (VC) solid-shaft electronics with an adjusting wheel allow for material-specific speeds that remain almost constant under load. The electronic safety shutdown of the motor activates in case of blocking of the insert tool for safe working, along with electronic overload protection, soft start, and restart protection. The slim design ensures optimum handling.
