Part of the GEN2 T-A series, this insert features a 144-degree point angle and an AM200 PVD coating that extends tool life when cutting through tough workpiece materials. The insert measures 3-3\/4 inches in diameter with a Seat Size 7 designation and a thickness of 0.4375 inches. It is intended for use in compatible T-A style spade drill holders and is installed by machinists and tooling technicians 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, titanium, and hard materials — covering ISO material groups P, M, K, S, and H. It is appropriate for CNC machining centers, lathes, and manual drill press setups where a replaceable-insert spade drill system is already in use. The GEN2 T-A series is a common choice in production environments where consistent hole geometry and insert interchangeability are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-3\/4 inch diameter cutting edge for large-bore drilling operations\u003c\/li\u003e\n  \u003cli\u003e144-degree point angle reduces thrust and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides heat resistance and toughness in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating extends wear life across steel, stainless, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eSeat Size 7 designation ensures compatibility with the correct GEN2 T-A holder body\u003c\/li\u003e\n  \u003cli\u003e0.4375-inch insert thickness for secure seating and rigid support during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holder bodies requiring a Seat Size 7 insert.

Use the manufacturer-specified insert screw and driver to seat the insert flush against the holder pocket — do not substitute fasteners. Inspect the holder pocket for wear or debris before installing a new insert, as a damaged seat will affect hole accuracy and insert life. Follow the holder manufacturer's clamping procedure to ensure the insert is fully engaged before returning the tool to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 144 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.4375 inches\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: AM200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GEN2 T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, 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: 457H-0324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51747925229874,"sku":"457H-0324","price":190.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfb3edf3835887fef719236963a8bd90.jpg?v=1788887153","url":"https:\/\/voomisupply.com\/products\/allied-machine-457h-0324-spade-drill-insert-3-3-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
