Part of the T-A series, this insert measures 33\/64 inches in diameter and features a 132-degree point angle for aggressive, accurate penetration. Coated with TiAlN via a PVD process, it delivers superior heat resistance and extended tool life when cutting tough materials. At 0.125 inches thick and weighing 0.1 pounds, it is a precision-ground replaceable insert intended for use with compatible T-A series spade drill holders. Installation is performed by qualified machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for cutting stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. It carries a C2 (K20) manufacturer grade, making it well-suited for both roughing and finishing passes in CNC machining centers, drill presses, and manual lathes where consistent hole quality and insert longevity are required. The T-A series platform is widely used in production environments where rapid insert changeover reduces downtime and maintains dimensional accuracy across high-volume drilling runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e33\/64 inch diameter with 132-degree point angle for precise, self-centering entry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction at C2 (K20) grade for wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating applied via PVD process for high heat resistance and extended cutting life\u003c\/li\u003e\n\u003cli\u003eCompatible with T-A series Seat Size 0 spade drill holders for fast, repeatable insert changes\u003c\/li\u003e\n\u003cli\u003eRated for stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium workpieces\u003c\/li\u003e\n\u003cli\u003e0.125 inch insert thickness with a package quantity of one insert per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T-A series spade drill holders accepting Seat Size 0 inserts.
