The highly rigid and stable Steadyline ® system effectively reduces unwanted vibrations in extreme cutting conditions via a “dynamic passive system” inside the holder body where a damping mass counter vibrates against the first flex vibration. As such, these products can perform typical long overhang operations twice as fast as traditional tools, reduce spindle stress as well as offer high metal-removal rates, smooth part surface finishes and long tool life.

This enables machining over 5xD overhang with cutting speeds similar to short assemblies, increasing depth of cut by up to 3 times compared to classic long holders SM-K-L1 (“5555”) cylindrical shape M…K (K821) cylindrical shape 37 www.secotools.com
