Sized at 29.5 mm diameter with a Seat Size 2 designation, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life when cutting through hard, abrasive, or heat-generating workpiece materials. At 0.04 pounds and 0.1875 inches thick, it is a compact, precision-ground component designed for use in compatible T-A style spade drill holders. Machinists and tool-crib professionals in production and job-shop environments rely on this insert for repeatable, consistent hole quality.\u003c\/p\u003e\u003cp\u003eThis insert is rated for use across a broad range of primary workpiece materials including Steel (P), Stainless Steel (M), Cast Iron (K), Super-alloys and Titanium (S), and Hard Material (H). It is part of the GEN2 T-A series product line, making it suited for production drilling operations where insert changeability and consistent hole geometry are priorities. Typical applications include structural fabrication, aerospace component machining, and general metalworking where through-coolant or high-feed drilling is required in a machine shop or manufacturing cell environment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e29.5 mm cutting diameter with Seat Size 2 for correct holder fit\u003c\/li\u003e\n\u003cli\u003e132-degree point angle reduces thrust and improves chip formation on entry\u003c\/li\u003e\n\u003cli\u003eCobalt substrate provides toughness and heat resistance in difficult materials\u003c\/li\u003e\n\u003cli\u003eAM200 PVD coating increases surface hardness and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003eRated for Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium, and Hard Materials\u003c\/li\u003e\n\u003cli\u003eGEN2 T-A series design for compatibility with Allied T-A spade drill holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holders requiring a Seat Size 2 insert.
