This insert features a 132-degree point angle and a titanium carbonitride (TiCN) physical vapor deposition (PVD) coating that increases surface hardness and reduces tool wear during extended cutting cycles. With a seat size of 1 and a 0.1563-inch thickness, it mounts into compatible T-A series spade drill holders. It is installed by machinists, toolroom technicians, and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium workpieces — covering ISO material groups P, M, K, and S. It is commonly used in horizontal and vertical machining centers, lathes with live tooling, and manual drill presses where the T-A spade drill system is in use. The 59\/64-inch diameter makes it appropriate for applications requiring a precise, near-1-inch bore without reaming pre-stock removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e59\/64-inch cutting diameter for near-1-inch bore applications\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle reduces thrust force and improves chip formation\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides heat and wear resistance beyond standard high-speed steel\u003c\/li\u003e\n  \u003cli\u003eTiCN PVD coating extends tool life when cutting ferrous and difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eSeat size 1 for compatibility with T-A series spade drill holder bodies\u003c\/li\u003e\n  \u003cli\u003e0.1563-inch insert thickness for precise seating and rigidity in the holder\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 holder bodies.

Ensure the spade drill holder is removed from the spindle and the machine is in a de-energized, locked-out state before inserting or removing the blade. Seat the insert fully against the holder pocket and secure with the appropriate clamping screw to the holder manufacturer's specified method. Inspect the insert seat and holder pocket for chips or debris before each installation to ensure proper blade contact and runout control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 59\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium\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: 151N-.921\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51731041747250,"sku":"151N-.921","price":63.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b34bb7b20e87d378c3eea91b80d3b39_4d3bff01-90e3-4aed-ae4c-f993043c46d8.jpg?v=1788726172","url":"https:\/\/voomisupply.com\/products\/allied-machine-151n-921-spade-drill-insert-59-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
