Flexible and extremely rugged: the ARNO AKB system for drilling holes up to 5 x D.
The AKB system just keeps on running – on milling or turning machines, with interrupted cuts, at low and high feed rates and for drilling offsets. How does it work? For example, it’s due to the coated and polished tool holder with large chip chambers, including optimised run-out in the collar for smooth chip evacuation. Or due to the large ground collar which ensures a stable flat face in the holder. Much longer tool life and best results come from the through tool coolant supply, the robust centre flute, the strong cutting edges and the corner radii of the indexable inserts.
Besides its stability, the quality of the results, its handling and versatility of the AKB are its strong features: The positive drift leaves no retraction marks on the workpiece. The indexable inserts with four efficient flutes are identical on the inside and outside – a practical feature when fitting. Torx Plus® screws ensure the inserts have a stable, secure and solid seat. And the different indexable insert geometries and grades makes this system ideal for a wide range of applications at different feed rates.
