With a 7\/8 inch diameter, a 180-degree point angle, and a Physical Vapor Deposition (PVD) TiN coating, this insert delivers consistent cutting performance and extended tool life. It belongs to the T-A Series and is sized to Seat Size 1. The C2 (K20) carbide grade provides the hardness and wear resistance required for production drilling applications. Installation and use is typical for machining centers, CNC lathes, and drill presses operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for drilling into a broad range of workpiece materials including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. The T-A Series is a well-established spade drill platform commonly used in production machining environments where consistent hole quality and insert replaceability are required. The TiN PVD coating reduces built-up edge and improves chip flow when working through harder or more abrasive materials. Package quantity is 1 insert per package with a minimum order quantity of 2.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch diameter, Seat Size 1, T-A Series spade drill insert\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction with C2 (K20) manufacturer grade for high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e180-degree point angle for flat-bottom entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating reduces friction, extends tool life, and resists built-up edge\u003c\/li\u003e\n  \u003cli\u003eCompatible with stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003eFractional inch measurement system; 0.1563 inch insert thickness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A Series Seat Size 1 spade drill holders as specified by Allied Machine and Engineering.
