It features a 20 mm cutting diameter, a 180-degree point angle for flat-bottom entry, and is manufactured from cobalt steel for improved hardness and heat resistance. A PVD-applied TiN (titanium nitride) coating reduces friction and extends cutting life in demanding production environments. This insert is part of Allied's T-A Series, a modular spade drilling system where the insert seats into a reusable holder. It is installed by machinists and tooling technicians in production shops, job shops, and maintenance machining operations.\u003c\/p\u003e\n\u003cp\u003eThe 151T-20-FB fits Seat Size 1 T-A Series holders and is intended for drilling steel, stainless steel, cast iron, super-alloys, and titanium. The cobalt substrate and TiN coating make it particularly well-suited for harder ferrous materials and work-hardening alloys where high-speed steel inserts lose edge integrity quickly. Typical applications include through-hole and blind-hole drilling on CNC machining centers, lathes with live tooling, and drill presses running moderate to high feeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 mm cutting diameter in the T-A Series modular spade drill system\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides superior hardness and thermal resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating reduces built-up edge and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e180-degree point angle enables flat-bottom entry and reduces axial thrust\u003c\/li\u003e\n  \u003cli\u003eSeat Size 1 interfaces directly with compatible T-A Series spade drill holders\u003c\/li\u003e\n  \u003cli\u003eRated for use in steel, stainless steel, cast iron, super-alloys, and titanium workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Seat Size 1 T-A Series spade drill holders.

Power down and lock out the machine spindle before seating or removing the insert. Ensure the holder pocket and insert seating surfaces are clean and free of chips before installation, as debris under the insert will cause premature edge failure or holder damage. Follow the holder manufacturer's torque and clamping specifications for the T-A Series retention screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 180 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: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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\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  \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: 151T-20-FB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51729489592626,"sku":"151T-20-FB","price":157.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ada8b0f4d2c3530cc67b572f07355ed2.jpg?v=1788705218","url":"https:\/\/voomisupply.com\/products\/allied-machine-151t-20-fb-spade-drill-insert-20mm-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
