Built to T-A Series specifications, this insert features a 132-degree point angle and a TiCN (titanium carbonitride) PVD coating that extends tool life by reducing friction and resisting heat buildup at the cutting edge. With a 1\/2 inch diameter and Seat Size Z designation, it fits directly into compatible T-A Series spade drill holders without modification. At 0.0938 inches thick, the insert is designed for precision seating and repeatable positioning. Machinists and tool-room technicians working in production environments rely on this insert for consistent hole quality across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for use on steel, stainless steel, cast iron, super-alloys, and titanium, covering ISO material groups P, M, K, and S. It is well suited for production drilling operations on CNC machining centers, horizontal boring mills, and manual lathes where a replaceable spade drill insert is preferred over a solid or brazed-tip tool. The T-A Series platform is commonly found in job shops and manufacturing facilities performing high-volume hole-making in ferrous and exotic alloy components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch cutting diameter with Seat Size Z for direct T-A Series holder fitment\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and heat resistance in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eTiCN PVD coating reduces built-up edge and extends cutting life on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle suits flat-bottom and through-hole drilling on a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, and titanium (ISO P, M, K, S)\u003c\/li\u003e\n  \u003cli\u003eReplaceable insert design lowers tooling cost versus solid drill replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A Series spade drill holders accepting a Seat Size Z insert at 1\/2 inch diameter.

Seat the insert fully against the holder pocket and torque the clamping screw to the holder manufacturer's specification using a calibrated torque wrench. Inspect the seating surface and cutting edges for chips or debris before securing the insert. Follow shop safety protocols and applicable OSHA machine-guarding standards when changing tooling on powered equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: Z\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 15ZN-0016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51731898368306,"sku":"15ZN-0016","price":58.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2594bedb830dbda4adbc5ea82402b89.jpg?v=1788736278","url":"https:\/\/voomisupply.com\/products\/allied-machine-15zn-0016-spade-drill-insert-1-2-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
