Sized at 7\/16 inch diameter with a Seat Size Z designation, this insert fits T-A Series spade drill holders. The 132-degree point angle is suited for work in steel, stainless steel, and cast iron. A TiN (titanium nitride) PVD coating reduces friction and extends cutting edge life. At 0.0938 inches thick, this insert delivers consistent geometry and reliable seating in compatible T-A Series bodies. Machinists and tool crib operators working in production environments will find this a direct OEM-compatible replacement or fresh supply insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in T-A Series spade drill holder bodies across a range of metalworking operations. Primary workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, corresponding to ISO material codes P, M, K, S, and H. It is well suited to CNC machining centers, lathes with live tooling, and dedicated drill presses in job shop or production settings where controlled hole entry and exit are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16 inch diameter, Seat Size Z for T-A Series spade drill bodies\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides heat and wear resistance in tough workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiN PVD coating reduces built-up edge and extends tool life\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle optimized for steel and ferrous alloy drilling\u003c\/li\u003e\n  \u003cli\u003e0.0938 inch insert thickness for consistent seating and repeatable geometry\u003c\/li\u003e\n  \u003cli\u003eCompatible with ISO material groups P, M, K, S, and H workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A Series spade drill holder bodies requiring a Seat Size Z, 7\/16 inch diameter insert.
