Sized at 22.5 mm in diameter with a 132-degree point angle, this insert fits Seat Size 1 holders in the GEN2 T-A spade drill system. The AM200 PVD coating enhances wear resistance and extends tool life when cutting through tough materials. At 0.1563 inches thick and weighing approximately 0.1 pounds, this insert is a direct, repeatable replacement that maintains consistent hole geometry across production runs. Licensed machinists and tool-room technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for production and job-shop drilling in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A platform is widely used in CNC machining centers and drill presses where indexable spade tooling is preferred over solid-carbide alternatives for cost efficiency at larger diameters. The AM200 PVD coating makes it particularly suited for dry or light-lubrication cutting strategies in ferrous and difficult-to-machine workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e22.5 mm cutting diameter with 132-degree split-point geometry for accurate hole entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and thermal resistance in interrupted or variable-hardness cuts\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating extends tool life across steel, stainless, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eSeat Size 1 interface fits standard GEN2 T-A spade drill holders for secure, repeatable indexing\u003c\/li\u003e\n  \u003cli\u003e0.1563-inch insert thickness maintains rigidity and minimizes deflection at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity is 2 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Seat Size 1 GEN2 T-A spade drill holders from ALLIED MACHINE AND ENGINEERING.

Use the correct T-A insert seating wrench to secure the insert against the holder pocket; do not overtighten with non-rated tools. Inspect the holder pocket and seating surfaces for chips or debris before each insert change to ensure proper seating and runout. Follow the machine tool manufacturer and ALLIED MACHINE AND ENGINEERING guidelines for recommended speeds and feeds for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 22.5 mm\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\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\u003eSeat Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 451H-22.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51737216319794,"sku":"451H-22.5","price":141.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/168335fd1f682f575c58a014de48ad89_8e080cc9-c270-4f06-b91c-e953b5e82179.jpg?v=1788785682","url":"https:\/\/voomisupply.com\/products\/allied-machine-451h-22-5-spade-drill-insert-22-5mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
