Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life in abrasive and high-heat cutting environments. At 0.1875 inches thick and sized for a Seat Size 2 holder, it delivers consistent chip control and cutting geometry across a range of primary workpiece materials. Installed by machinists and tooling technicians, it fits standard spade drill blade holders used in CNC and manual machining operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production drilling in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A series is commonly applied in aerospace, oil and gas, die and mold, and general manufacturing environments where hole quality and tool longevity are critical. The AM200 PVD coating provides thermal stability and wear resistance, making this insert a dependable choice for interrupted cuts and continuous drilling cycles at elevated feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-3\/8 inch diameter with Seat Size 2 for precise holder fit\u003c\/li\u003e\n\u003cli\u003e132-degree point angle for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003eCobalt substrate provides toughness in interrupted and high-stress cuts\u003c\/li\u003e\n\u003cli\u003eAM200 PVD coating improves wear resistance and thermal performance\u003c\/li\u003e\n\u003cli\u003eCompatible with P, M, K, S, and H workpiece material classifications\u003c\/li\u003e\n\u003cli\u003eGEN2 T-A series geometry optimized for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GEN2 T-A series Seat Size 2 spade drill blade holders.
