Operating optimally in the ISO P05-P25 application band, this negative double-sided triangular insert features Sumitomo’s breakthrough \u003cstrong\u003eAC820P Absotech Platinum Super Texturized CVD coating\u003c\/strong\u003e technology. By combining a highly dense $TiCN$ inner layer with a highly uniform alpha-alumina ($Al_2O_3$) outer crystal structure, this grade creates an impenetrable thermal shield over a highly deformation-resistant carbide substrate. The advanced \u003cstrong\u003eUX chipbreaker geometry\u003c\/strong\u003e incorporates a specialized variable-angle rake flank and a wavy chip-control groove, dropping cutting forces while delivering reliable chip evacuation during continuous medium-roughing operations.
