L.ADU C-Frame locking system for one-shot drilling and countersinking, with up to 100% chip and dust exhaust and quick changeover via the Quick Change System.
The L.ADU C-Frame locking system is designed for one-shot drilling and countersinking, with up to 100% chip and dust exhaust and clamping force up to 1,200 N.
It clamps the L.ADU drilling unit into a designated template attached to the aircraft component, positions it vertically, and absorbs the feed force so the clamping force exceeds the drilling force.
