This insert measures 1-7\/8 inches in diameter and fits Seat Size 3 holders. It features a 132-degree point angle and is manufactured from premium cobalt steel with an AM200 PVD coating for extended tool life and heat resistance. The GEN2 T-A series design provides rigid support and efficient chip evacuation during deep-hole drilling. Machinists and CNC operators working in production environments will find this insert well-suited for high-feed drilling operations across a range of difficult workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for use in steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material classifications P, M, K, S, and H. It is appropriate for both manual and CNC-controlled machining centers in job shop and production floor environments. The GEN2 T-A series is a modular spade drilling system, and this insert is intended for use with the corresponding Seat Size 3 spade drill body or holder. Typical applications include through-hole and blind-hole drilling in heavy equipment manufacturing, aerospace component work, and general metalworking.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-7\/8 inches cutting diameter with Seat Size 3 compatibility\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle optimized for chip formation and entry stability\u003c\/li\u003e\n  \u003cli\u003ePremium cobalt construction for toughness and wear resistance at elevated temperatures\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating reduces friction and extends insert life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eGEN2 T-A series design for reliable indexing and repeatability\u003c\/li\u003e\n  \u003cli\u003eCovers five ISO workpiece material classifications: P, M, K, S, and H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series Seat Size 3 spade drill holders and bodies.
