Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM300 PVD coating that extends tool life and maintains cutting edge integrity across a range of difficult workpiece materials. At 0.421 inches in diameter with a Seat Size Y designation, it is engineered to seat precisely in compatible T-A spade drill holders. Machinists, toolroom technicians, and CNC operators install this insert when drilling operations require consistent performance in tough materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. It is designed for production and job-shop environments where material grades M, K, N, and S are commonly encountered. The GEN2 T-A platform is widely used in horizontal and vertical machining centers as well as manual drilling setups requiring replaceable insert tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27\/64 inch (0.421 inch) diameter with Seat Size Y for precise holder fit\u003c\/li\u003e\n\u003cli\u003e132-degree point angle optimized for controlled entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction at manufacturer grade C2 (K20) for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAM300 PVD coating extends cutting tool life in abrasive and work-hardening materials\u003c\/li\u003e\n\u003cli\u003eCompatible primary workpiece materials include stainless steel, cast iron, non-ferrous metals, and super-alloys and titanium\u003c\/li\u003e\n\u003cli\u003eGEN2 T-A series design for repeatable insert indexing and seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holders accepting Seat Size Y inserts at 27\/64 inch diameter.
