Manufactured from C5 (P40) grade carbide and coated with TiN via a PVD process, this insert delivers wear resistance and thermal stability in demanding drilling applications. The 132-degree point angle suits flat-bottomed entry and through-hole drilling on tougher workpiece materials. At 0.1563 inches thick and sized for a Seat Size 1 holder, it fits directly into compatible T-A series spade drill bodies. Machinists and tool-room technicians working in production or job-shop environments specify this insert for reliable, repeatable cutting performance.\u003c\/p\u003e\n\u003cp\u003eThis insert is part of the Allied Machine T-A series and is intended for use in ferrous materials including steel and hard alloys. It is well suited to CNC machining centers, drill presses, and turning centers where spade drilling is preferred over twist drills for large-diameter hole making. The 49\/64 inch diameter and Seat Size 1 designation make it a direct fit for T-A series spade drill bodies of the corresponding seat size. Typical applications include production drilling in automotive, aerospace, and general metalworking environments where carbide tooling is required for tool life and cut quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e49\/64 inch diameter with 132-degree point angle for flat entry and accurate hole geometry\u003c\/li\u003e\n  \u003cli\u003eC5 (P40) grade carbide substrate rated for steel and hard material applications\u003c\/li\u003e\n  \u003cli\u003eTiN coating applied via PVD process for improved surface hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSeat Size 1 designation for direct compatibility with T-A series spade drill bodies\u003c\/li\u003e\n  \u003cli\u003e0.1563 inch insert thickness for consistent seating and repeatable tool length\u003c\/li\u003e\n  \u003cli\u003eFractional inch measurement system for straightforward specification in imperial tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Allied Machine T-A series spade drill bodies in Seat Size 1. Compatible primary workpiece materials include steel and hard materials (material grade codes P and H). Confirm seat size and body series before ordering to ensure proper insert seating and retention.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torque wrench and insert screw specified by the drill body manufacturer — do not over-tighten the retention screw, as carbide inserts are brittle and can crack under uneven clamping force. Inspect the insert seat for chips or debris before installation to ensure full contact and accurate positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 49\/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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: C5 (P40)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel and Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1C51T-.765\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51728686612786,"sku":"1C51T-.765","price":86.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/642eeecfcd7bcafaa57d448ff867b923.jpg?v=1788695014","url":"https:\/\/voomisupply.com\/products\/allied-machine-1c51t-765-spade-drill-insert-49-64-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
