Measuring 27\/32 inches in diameter and seating in a Size 1 holder, this insert is manufactured from M4 high speed steel and carries a TiAlN (titanium aluminum nitride) PVD coating. The 132-degree point angle makes it well suited for flat-bottom entry and exit on steel, cast iron, and non-ferrous metals. Machinists and tooling professionals working in production drilling applications rely on inserts like this for repeatable performance without the cost of regrinding solid drills.\u003c\/p\u003e\n\u003cp\u003eThis insert belongs to the T-A Series, a widely used indexable spade drill platform. It fits Size 1 T-A Series spade drill holders and is intended for use in CNC machining centers, lathes with live tooling, or drill presses running appropriate speeds and feeds for the workpiece material. Primary workpiece material classifications are P (steel), K (cast iron), and N (non-ferrous metal), making this insert a versatile choice across general metalworking and production machining environments. The TiAlN coating improves heat resistance and tool life when cutting at elevated surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/32 inch diameter, Size 1 seat  -  direct fitment into T-A Series Size 1 spade drill holders\u003c\/li\u003e\n  \u003cli\u003eM4 high speed steel construction provides toughness and edge retention in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating improves oxidation resistance and extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle supports clean entry and reduced thrust in production drilling\u003c\/li\u003e\n  \u003cli\u003eCompatible with P, K, and N workpiece material classifications (steel, cast iron, non-ferrous metals)\u003c\/li\u003e\n  \u003cli\u003eIndexable insert design reduces tooling cost compared to regrinding solid HSS drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A Series Size 1 spade drill holders.

Always power down and lock out the machine spindle before seating or removing the insert. Ensure the holder seat is clean and free of chips before installing the insert, as debris under the seat can affect runout and lead to premature insert failure. Follow the holder manufacturer's torque guidance for the insert screw and verify correct speeds and feeds for the workpiece material before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 27\/32 inches\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: 132 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M4\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\u003eThickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\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: 131A-0027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":68079405629746,"sku":"131A-0027","price":60.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/018dd13e89e27846da59559c85267889_2d1b865a-1d53-47dc-bcfc-bf8c18f79c27.jpg?v=1793120812","url":"https:\/\/voomisupply.com\/products\/allied-machine-131a-0027-spade-drill-insert-27-32-in-hss-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
