New insert grade material from Sandvik Coromant offers exceptional wear resistance

February 25, 2014

Sandvik Coromant has announced that it will be introducing new insert grades for steel turning and cast iron milling incorporating its Inveio branded technology. “The material represents a technical breakthrough in material science and provides inserts with exceptional wear resistance and tool life,” stated the company.

Following the successful introduction of insert grade GC4325 in October 2013, Sandvik Coromant will also offer new grades GC4315 and GC3330. All three grades feature Inveio which the company claims brings endurance, predictability and long tool life to the machining process.

Sandvik Coromant states that the performance of these grades is made possible by Inveio’s uni-directional crystal orientation. Normally, the crystal orientation of the CVD alumina coating is random, however the company claims to have found a way to control the growth of the crystals, lining them up in the same direction to create a stronger, uniform structure of the coating. These tightly-packed crystals create a strong barrier towards the cutting zone and chip.

The result is grades that offer improved wear resistance and cutting edges that stay in shape and last longer in the cut. The long, predictable tool life of GC4325, GC4315 and GC3330 enables secure unmanned production with a high metal removal rate.
