We always remember that speed is one of the key success factors in our business. For this reason, we are committed to provide an agile response in the offer, optimizing the final geometry, the grinding allowance, as well as advising to our customers on the choice of the optimal grade of hard metal depending on the application.
In this process, the metallographic characterization carried out by our laboratory is essential to support decision-making in new developments and applications.
Finally, our Technical Sales department works in continuous contact with each customer, visits their plants to listen and improve their proposals.
