Built from cobalt high-speed steel and finished with an AM200 PVD coating, this insert delivers extended tool life and thermal resistance in tough cutting applications. With a 132-degree point angle and Seat Size 1 classification, it fits directly into compatible GEN2 T-A spade drill holders. Licensed machinists and tooling technicians install this insert as a replacement or production-run consumable in CNC turning centers, machining centers, and drill presses running at production feed and speed rates.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for use across a broad range of primary workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials — covering ISO material codes P, M, K, S, and H. It is well suited for both through-hole and blind-hole drilling operations in high-volume manufacturing, aerospace, automotive, and general metalworking shops where consistent hole quality and insert longevity are priorities. The AM200 PVD coating provides a hard, low-friction surface layer that reduces built-up edge and extends cutting performance between tool changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e22 mm cutting diameter with 132-degree point angle for aggressive chip formation and accurate entry\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and heat resistance beyond standard HSS inserts\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating reduces friction, resists crater wear, and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSeat Size 1 — compatible with GEN2 T-A spade drill holder bodies\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (ISO P, M, K, S, H)\u003c\/li\u003e\n  \u003cli\u003eSold individually — direct drop-in replacement for production tooling changeouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GEN2 T-A series Seat Size 1 spade drill holders.

Always power down and lock out the machine spindle before removing or seating a drill insert. Seat the insert fully and evenly in the holder pocket and secure with the manufacturer-specified clamping screw — do not overtighten with impact tools. Inspect the holder pocket for chips, burrs, or wear before installing a new insert, as pocket damage will affect runout and hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 22 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\u003eLength\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium, Hard Material (ISO P, M, K, S, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 451H-22-HE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51738735411506,"sku":"451H-22-HE","price":78.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13025c978a6ae2d23bc52256be63c40e.jpg?v=1788803644","url":"https:\/\/voomisupply.com\/products\/allied-machine-451h-22-he-spade-drill-insert-22mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
