Part of the T-A series, this insert features a 132-degree point angle and a titanium aluminum nitride (TiAlN) PVD coating that extends tool life under high heat and cutting pressure. At 59\/64 inches in diameter with a Seat Size 1 designation, it fits directly into compatible T-A series spade drill holders. Machinists and tooling professionals in production and job-shop environments install this insert when drilling through steel, stainless steel, cast iron, and super-alloys including titanium.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for CNC machining centers, manual lathes, and drilling operations where repeatability and insert interchangeability are required. The T-A series platform allows the insert to be indexed or replaced without removing the holder from the spindle, reducing downtime in high-volume production runs. Primary workpiece materials include carbon and alloy steels, stainless steels, cast iron, super-alloys, and titanium, making it a versatile choice across aerospace, automotive, and general manufacturing applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e59\/64 inches diameter with Seat Size 1 for T-A series holder compatibility\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 increased hardness and heat resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating extends cutting life in high-temperature, abrasive materials\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003eInsert-style design allows quick changeout without removing the drill body from the machine\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Seat Size 1 T-A series spade drill holders.
