Powered by ZCC-CT's versatile \u003cstrong\u003eYBC252 multi-layer CVD coated carbide grade\u003c\/strong\u003e—combining a tough gradient-sintered tungsten carbide substrate with a thick, heat-resistant TiCN-Al2O3 chemical vapor deposition (CVD) coating—this insert delivers exceptional thermal barrier properties and resistance against flank wear and crater wear under elevated cutting temperatures and continuous-to-light-interrupted cuts. Unlike thin PVD coatings optimized for lower-speed stainless steel machining, thick multi-layer CVD coatings on \u003cstrong\u003eYBC252\u003c\/strong\u003e provide superior thermal insulation during high-velocity steel turning. Paired with a crisp \u003cstrong\u003e0.4mm nose radius\u003c\/strong\u003e and the dedicated right-hand \u003cstrong\u003eZC positive chipbreaker\u003c\/strong\u003e, it minimizes cutting resistance, prevents chatter on slender shafts, and directs chips smoothly away from the workpiece.
