This insert measures 49\/64 inches in diameter and seats in a Size 1 holder. It is manufactured from M4 high speed steel and finished with a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating, which extends cutting edge life by reducing heat buildup and friction. The 132-degree point angle makes it well-suited for flat-bottomed entry and controlled chip formation. It belongs to the T-A Series, a widely recognized interchangeable spade drill platform. Machinists and tooling specialists working in production or job-shop settings are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is designed for drilling into steel, cast iron, and non-ferrous metals, covering ISO workpiece material codes P, K, and N. The T-A Series platform is commonly used in CNC machining centers, lathes, and drill presses where high-volume hole production demands consistent tool geometry. The TiN coating improves wear resistance when cutting ferrous materials at moderate to high cutting speeds, making this insert a practical choice for production runs where tool life and hole quality are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e49\/64-inch diameter for precise bore sizing in Size 1 T-A Series holders\u003c\/li\u003e\n\u003cli\u003eM4 high speed steel construction provides toughness and edge retention in interrupted cuts\u003c\/li\u003e\n\u003cli\u003eTiN PVD coating reduces friction and extends insert service life\u003c\/li\u003e\n\u003cli\u003e132-degree point angle supports accurate entry and reduces thrust force\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, cast iron, and non-ferrous metal workpieces\u003c\/li\u003e\n\u003cli\u003eT-A Series platform allows quick insert changeover without removing the holder from the spindle\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T-A Series Size 1 spade drill holders as part of the Allied Machine and Engineering T-A interchangeable spade drill system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert installation and replacement should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked. Use the appropriate insert seating tool or torque wrench recommended for T-A Series holders to secure the insert properly. Inspect the holder pocket for wear or debris before seating a new insert. Follow the machine tool manufacturer and tooling manufacturer guidelines for speeds, feeds, and coolant application specific to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 49\/64 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\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\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: 0.1563 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 131T-.765\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51749331239218,"sku":"131T-.765","price":53.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/888efb7f48a8647f85b55bb4451fb710_5ce45d99-0354-4e67-b520-aa63f9c2216c.jpg?v=1788904614","url":"https:\/\/voomisupply.com\/products\/allied-machine-131t-765-spade-drill-insert-49-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
