Sized at 18.00 mm in diameter with a 132-degree point angle, this insert is manufactured from Super Cobalt and carries an AM200 PVD coating for extended tool life and heat resistance. It belongs to the GEN2 T-A series, a platform recognized in the machining trade for modular spade drill tooling. Machinists, toolroom technicians, and production floor operators installing or replacing inserts in compatible T-A spade drill holders will find this a direct fit for the Seat Size 1 holder body.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. It is commonly used in CNC machining centers, manual lathes, and drill press setups across general manufacturing, aerospace, oil and gas, and heavy equipment industries. The AM200 PVD coating reduces built-up edge and improves performance in interrupted cuts and abrasive materials. The 18.00 mm diameter makes it appropriate for medium-diameter hole applications where a replaceable insert system offers cost and cycle-time advantages over solid drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18.00 mm cutting diameter with a 132-degree point angle for reduced thrust and accurate entry\u003c\/li\u003e\n  \u003cli\u003eSuper Cobalt insert material for improved toughness and heat resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating classification for extended wear life across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003eGEN2 T-A series platform — Seat Size 1 for compatibility with corresponding T-A holder bodies\u003c\/li\u003e\n  \u003cli\u003eRated for ISO material groups P, M, K, S, and H including stainless steel, cast iron, and superalloys\u003c\/li\u003e\n  \u003cli\u003eMetric measurement system; thickness of 0.1563 inches\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 Seat Size 1 insert.

Use the correct T-A insert key or torx driver specified for the holder to seat the insert fully and evenly — do not overtighten or use impact tools. Inspect the holder pocket for damage or debris before seating a new insert. Handle cobalt inserts carefully to avoid chipping the cutting edge during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 18.00 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 (Super 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\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, S, H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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-18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51728821944626,"sku":"451H-18","price":79.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/168335fd1f682f575c58a014de48ad89_24817c2e-7f13-457a-8e04-8aeb3e867294.jpg?v=1788696423","url":"https:\/\/voomisupply.com\/products\/allied-machine-451h-18-spade-drill-insert-18mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
