With a 7\/8-inch diameter and a 132-degree point angle, this insert seats in a Size 1 holder and is part of the GEN2 T-A series. The AM200 PVD coating improves wear resistance and heat dissipation, extending tool life in abrasive or high-heat cutting environments. At 0.02 pounds, it is a compact, precision-ground insert suited for production drilling operations where consistency and insert-to-insert repeatability are critical. Licensed machinists and tool-room technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for use across a broad range of workpiece materials, including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is appropriate for both job-shop and production-floor environments where a single insert geometry must handle varied material types. The GEN2 T-A platform is a modular spade drilling system, meaning the insert seats into a reusable T-A style holder rather than a disposable drill body, reducing tooling cost per hole over high-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-inch diameter with 132-degree point angle for aggressive chip formation and accurate entry\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides elevated hot hardness for cutting steel, stainless, and super-alloys\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating reduces friction and extends edge life in abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSize 1 seat fits standard GEN2 T-A compatible holders for quick changeover\u003c\/li\u003e\n  \u003cli\u003eRated for ISO material groups P, M, K, S, and H, covering a wide range of ferrous and exotic materials\u003c\/li\u003e\n  \u003cli\u003e0.1563-inch insert thickness maintains rigidity at the cutting edge during high-feed drilling\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 holders accepting a Size 1 seat.

Ensure the machine spindle is fully stopped and the tool is secured in the holder before insert changeout. Inspect the seat pocket for chips or debris before seating the insert, as contamination can cause insert rocking and premature edge failure. Always reference the holder manufacturer's documentation for correct clamping hardware and recommended cutting parameters for the target workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\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: GEN2 T-A\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\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches\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\u003eISO Material Group Codes\u003c\/strong\u003e: 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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\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-0028-HE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730753683762,"sku":"451H-0028-HE","price":137.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/117c244d980eb6feb9ba1903e720108f.jpg?v=1788722273","url":"https:\/\/voomisupply.com\/products\/allied-451h-0028-he-spade-drill-insert-7-8-in-cobalt-am200","provider":"Voomi Supply","version":"1.0","type":"link"}
