Modular and precise: the ARNO Mini-System AMS for internal machining starts at a diameter of 0.7 mm and reaches drilling depths of up to 50 mm.

Rigid centring, guaranteed tip height and absolute dimensional accuracy – it’s so easy with AMS for flexible operations in holes with small diameters.

This is how it works: The insert is clamped rigidly in central position by a ground chamfer on the shank and a tapered pin. A fixed stop guarantees repeatable positioning at tip height. Besides tool holders, there are also inserts with inner cooling to achieve optimised wear protection and precise coolant supply. This results in reliable processes, maximum precision even at tight tolerances and an increase of one to four times in tool life.
