Part of the GEN2 T-A series, this insert features a 132-degree point angle and a PVD-applied TiN coating that extends cutting edge life and reduces built-up edge in tough materials. At 2-9\/16 inches in diameter with a Seat Size 4 designation, it fits Allied Machine GEN2 T-A spade drill holders and is installed by machinists and tooling technicians on CNC turning centers, machining centers, and drill presses. The insert measures 0.3125 inches thick and weighs approximately 0.1 pounds.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for production drilling in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is used in both job-shop and high-volume manufacturing environments where consistent hole geometry and tool life are critical. The GEN2 T-A platform is a common choice in aerospace, automotive, and general metalworking applications where replaceable spade inserts reduce tooling changeover time compared to solid drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-9\/16 inch diameter with Seat Size 4 for GEN2 T-A spade drill holders\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle for balanced entry and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and heat resistance in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating reduces friction and extends cutting edge service life\u003c\/li\u003e\n  \u003cli\u003eCompatible primary workpiece material codes: P, M, K, S, and H\u003c\/li\u003e\n  \u003cli\u003eSingle insert per package with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Allied Machine and Engineering GEN2 T-A series spade drill holders requiring a Seat Size 4 insert.

Use the appropriate torque wrench and insert screw specified by the holder manufacturer when seating the insert — do not overtighten or substitute fasteners. Inspect the holder seat for chips or damage before installing a new insert. Machinists should follow their facility safety procedures and applicable ANSI or shop-floor tooling standards when handling carbide and cobalt cutting inserts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 4\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\u003eSeries\u003c\/strong\u003e: GEN2 T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys and Titanium, Hard Material\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: 454T-0218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51748429201714,"sku":"454T-0218","price":98.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3529d2c50fe935f95ec8a7cd795ee4f5_d8fd6eff-e04c-4c6b-818f-c18acf2669b4.jpg?v=1788893717","url":"https:\/\/voomisupply.com\/products\/allied-machine-454t-0218-spade-drill-insert-2-9-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
