Powered by TaeguTec's advanced \u003cstrong\u003eTT8115 multi-layer CVD coated carbide grade\u003c\/strong\u003e, this insert combines a high-strength tungsten carbide substrate with a thick, heat-resistant chemical vapor deposition (CVD) coating designed to withstand extreme thermal loads, high cutting speeds, and severe abrasive flank wear during deep cuts. Unlike PVD coatings which maintain a sharper edge for lower-speed stainless steels, thick multi-layer CVD coatings excel in continuous steel turning by offering exceptional thermal insulation and crater wear protection at elevated spindle speeds. Paired with a rugged \u003cstrong\u003e1.2mm corner radius\u003c\/strong\u003e for maximum edge strength under high feed rates and the specialized \u003cstrong\u003eMT medium chipbreaker\u003c\/strong\u003e featuring an optimized positive rake land, it delivers smooth chip evacuation, excellent chip curling across heavy depths of cut, and superior tool life.
