Built from cobalt high-speed steel and finished with a PVD-applied TiAlN coating, this insert delivers improved heat resistance and extended tool life compared to uncoated alternatives. It features a 132-degree point angle and measures 23.02 mm (29\/32 inch) in diameter with a 0.1563-inch thickness. The 181A-0029-HI seats into a Size 1 T-A spade drill holder and is installed by machinists and toolroom technicians on lathes, machining centers, and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It covers a broad range of primary workpiece material classifications including P, M, K, S, and H categories under standard ISO material codes. Typical applications include production drilling in aerospace, oil and gas, die and mold, and general metalworking environments where a single insert must perform across multiple material types without tool changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e23.02 mm (29\/32 inch) cutting diameter for precise bore sizing\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and thermal stability at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating extends tool life in abrasive and high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle reduces thrust force and suits a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eT-A Series Size 1 seat interface for quick, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003e0.1563-inch insert thickness ensures rigid seating in the holder pocket\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.

Power down and lock out the machine spindle before seating or removing the insert. Use the correct T-A holder wrench to torque the insert screw to the holder manufacturer's specification — do not use improvised tools that may damage the seating surfaces. Inspect the holder pocket for chips or wear before every insert change to maintain concentricity and cutting performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 23.02 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch Fraction)\u003c\/strong\u003e: 29\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches\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\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, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 181A-0029-HI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51729240162610,"sku":"181A-0029-HI","price":70.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d965e6efe1e91f42c8d9edeefd0860e1.jpg?v=1788702157","url":"https:\/\/voomisupply.com\/products\/allied-machine-181a-0029-hi-spade-drill-insert-29-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
