Part of the GEN2 T-A series, this insert features a 144-degree point angle and an AM200 PVD coating for extended tool life and heat resistance. At 2-27\/32 inches in diameter with a Seat Size 5 designation and a thickness of 0.4375 inches, it is built to deliver consistent performance in production environments. Machinists and tool crib personnel handling medium-to-large diameter drilling operations will find this insert well-suited to their workflow.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in GEN2 T-A spade drill holders with a Seat Size 5 interface. It is engineered for drilling into a broad range of primary workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. Typical applications include heavy-duty production drilling in industrial machining centers and manual boring operations where consistent hole geometry is required. The AM200 PVD coating supports performance in both dry and coolant-assisted cutting environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-27\/32 inch diameter with Seat Size 5 for GEN2 T-A spade drill holder compatibility\u003c\/li\u003e\n\u003cli\u003e144-degree point angle for precise entry and reduced thrust in hard materials\u003c\/li\u003e\n\u003cli\u003eCobalt insert material provides high heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eAM200 PVD coating extends tool life across a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (material codes P, M, K, S, H)\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.1 pounds for easy handling during insert changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holders requiring a Seat Size 5 insert.
