AMS – ARNO Mini-System
made easy.
Klemmhalter – ARNO Mini-System

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.

Tool holders
Klemmhalter – ARNO Mini-System

Every application is covered by the tool holders: standard or offset, hydraulic or polygon shank, for multi spindle or Swiss type machines. Available with coolant supply for longer tool life.

AMS boring bars with indexable inserts

All the benefits of the AMS system with even greater efficiency: with AMS boring bars and the right indexable inserts.

AMS Inserts with internal cooling

Precise coolant supply for maximum wear resistance: Either with coolant supply from the top (IKO) - perfect for through hole or from the bottom (IKU) – perfect for blind holes.


Suitable for every application: from axial grooving to threading, for hardened materials, including CBN brazed.

Precise benefitsof the ARNO Mini-System

Rigid centring and easy tool changes thanks to the clever system of a ground chamfer on the shank and tapered pin

Up to 400% longer tool life thanks to significant reduction in wear

Precision and quality all inclusive – all inserts are fully ground, including the shank
