Part of the T-A series, this insert measures 31\/32 inches in diameter and features a 132-degree point angle for accurate hole entry and reduced thrust. Constructed from cobalt high-speed steel and finished with a TiAlN PVD coating, it delivers extended tool life in tough cutting conditions. The insert thickness is 0.1875 inches and it seats in a Size 2 holder body. It is the standard choice for machinists and tool-and-die professionals running spade drilling operations on CNC or manual equipment.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium — covering ISO material codes P, M, K, and S. Typical applications include through-hole and blind-hole drilling in production machining environments such as job shops, aerospace component manufacturing, and heavy equipment fabrication. The TiAlN coating provides thermal resistance at elevated cutting speeds, making this insert particularly effective in dry or semi-dry cutting conditions where heat buildup is a factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e31\/32 inch diameter with 132-degree point angle for precise entry and reduced axial force\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and resistance to heat at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating extends wear life when cutting steel, stainless steel, cast iron, and titanium\u003c\/li\u003e\n  \u003cli\u003eT-A series Seat Size 2 insert — mates with compatible T-A series holder bodies\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.1875 inches ensures proper seating and secure clamping in the holder\u003c\/li\u003e\n  \u003cli\u003eSold individually — minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A series Seat Size 2 spade drill holder bodies.

Ensure the machine spindle is fully stopped and locked out before inserting or replacing the spade drill insert. Seat the insert fully into the holder pocket and verify the clamping screw is properly torqued per the holder manufacturer specification before resuming operation. Inspect the insert seating surface and holder pocket for chips or debris prior to each installation to prevent misalignment or premature insert failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 31\/32 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 Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\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\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: 152N-0031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730473910578,"sku":"152N-0031","price":74.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e45bcfb7eb6cb4ab6168639a92f56090_34b89e52-85ad-4f51-ac62-f24093025568.jpg?v=1788718090","url":"https:\/\/voomisupply.com\/products\/allied-machine-152n-0031-spade-drill-insert-31-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
