ARNO manufactures 2.5 million indexable inserts per year. What makes our range so special is the largest selection of high-positive inserts, the wide range of intermediate radii, the precise design and the matching additively manufactured holders with internal cooling.

ARNO indexable inserts deliver outstanding performance. 
This is backed by 30 years of grinding expertise and the ability to edge-hone the inserts in-house. Thanks to our know-how, we can offer our customers a wide range of intermediate sizes. This makes machining options significantly more granular and processes more precise.  

Leaders in high-positive
One of ARNO’s key areas of focus is high-positive indexable inserts. Their special properties reduce cutting forces and vibrations, improve chip breaking and enhance the surface quality of the workpiece. We offer the widest range available.  

Optimally tailored to your objectives
We always have an ace up our sleeve and design indexable inserts to suit your processes and materials. We ensure that the three key parameters – geometry, cutting edge and coating – are optimally matched. Your benefits: high tool life and outstanding results.

Unique to ARNO: Additively manufactured holder
ARNO’s additively manufactured holder increases the service life of indexable inserts. 
Vibrations are reduced and the special internal cooling system dissipates heat and chips perfectly.
