This T-A series insert measures 63\/64 inches in diameter with a 132-degree point angle and a 0.1875-inch thickness. The TiCN (Titanium Carbonitride) PVD coating increases surface hardness and reduces friction, extending tool life in abrasive and high-temperature cutting conditions. Seat Size 2 corresponds to the T-A series holder standard, making replacement and indexing straightforward for machinists and tool crib personnel familiar with the Allied Machine T-A system.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production drilling operations across a range of workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium. Typical applications include job shop and production floor drilling on CNC machining centers, drill presses, and turret lathes where consistent hole diameter and tool life are critical. The cobalt substrate provides added toughness and heat resistance compared to standard high-speed steel, making it a practical choice for interrupted cuts and harder alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e63\/64-inch diameter for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003e132-degree point angle reduces thrust and improves chip formation on entry\u003c\/li\u003e\n\u003cli\u003eCobalt substrate offers superior heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiCN PVD coating extends tool life and lowers cutting friction\u003c\/li\u003e\n\u003cli\u003eT-A series Seat Size 2 for direct interchange with compatible Allied Machine holders\u003c\/li\u003e\n\u003cli\u003e0.1875-inch insert thickness provides rigidity in the holder pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Allied Machine and Engineering T-A series Seat Size 2 spade drill holders.

Ensure the machine spindle is fully stopped and the tool holder is secured in the turret or spindle before inserting or removing the spade drill insert. Seat the insert fully and evenly in the holder pocket and torque the clamping screw to the holder manufacturer specification. Inspect the seating pocket for chips or debris before each insert change to prevent insert rocking and premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 63\/64 inches\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: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cobalt\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\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: 152N-25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51749533909298,"sku":"152N-25","price":74.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e45bcfb7eb6cb4ab6168639a92f56090_c8ecbf54-41e8-4fea-aba8-0f83676684b0.jpg?v=1788907321","url":"https:\/\/voomisupply.com\/products\/allied-machine-152n-25-spade-drill-insert-63-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
