Part of the T-A Series, this insert measures 20 mm in diameter with a 132-degree point angle and is manufactured from cobalt high-speed steel for toughness and heat resistance. A TiAlN (titanium aluminum nitride) PVD coating extends tool life by reducing friction and improving wear resistance at elevated cutting temperatures. Thickness measures 0.1563 inches. This insert is used by machinists and tooling technicians in production and job-shop environments where accurate, repeatable drilling is required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium — ISO workpiece material groups P, M, K, and S. The T-A Series spade drill system is a common platform in production machining, typically used in CNC machining centers, lathes with live tooling, and dedicated drilling machines. Seat Size 1 designates the holder interface this insert fits. Applications include through-hole and blind-hole drilling in structural, aerospace, and general manufacturing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 mm cutting diameter with 132-degree point angle for reduced thrust and accurate hole entry\u003c\/li\u003e\n\u003cli\u003eCobalt substrate provides toughness and resistance to heat-induced deformation\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating reduces wear and extends insert life in abrasive and high-temperature cuts\u003c\/li\u003e\n\u003cli\u003eCompatible with Seat Size 1 T-A Series spade drill holders\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials\u003c\/li\u003e\n\u003cli\u003eThickness of 0.1563 inches ensures proper seating and repeatability in the holder\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Seat Size 1 T-A Series spade drill holders.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully and evenly in the holder pocket and secure with the appropriate fastener to the holder manufacturer's specified procedure — do not over-torque or under-torque the clamping screw. Inspect the insert seat for chips or debris before installation to ensure proper contact and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches\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: TiAlN\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: T-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Material Groups\u003c\/strong\u003e: P, M, K, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 151A-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51732584431922,"sku":"151A-20","price":113.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/018dd13e89e27846da59559c85267889_54d99bb9-8a11-49b9-93d5-fbf450ef8913.jpg?v=1788744674","url":"https:\/\/voomisupply.com\/products\/allied-machine-151a-20-spade-drill-insert-20mm-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
