Measuring 63\/64 inches in diameter with a 132-degree point angle, this insert fits a Seat Size 2 holder in the T-A series system. The insert is manufactured from T15 cobalt material grade and features a TiAlN PVD coating that extends tool life by reducing heat buildup and wear at the cutting edge. At 0.1875 inches thickness, it delivers consistent geometry across production runs. Machinists and tool and die professionals working in job shops, production facilities, and maintenance environments rely on this insert for repeatable, accurate drilling.\u003c\/p\u003e\n\u003cp\u003eThe 152A-25 is suited for drilling steel, stainless steel, cast iron, super-alloys, and titanium. These material categories correspond to workpiece classifications P, M, K, and S. The T-A series spade drill system is a common platform used in CNC machining centers, lathes with live tooling, and manual boring mills where replaceable insert tooling reduces downtime compared to solid drill replacement. The TiAlN coating provides thermal resistance particularly relevant when cutting stainless steel and titanium, where heat generation at the cutting zone is a primary concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e63\/64 inch cutting diameter for precise hole sizing without regrinding\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle suited for flat-bottom entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eT15 cobalt material grade offers high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating reduces heat buildup and extends insert life in tough materials\u003c\/li\u003e\n  \u003cli\u003eSeat Size 2 compatibility integrates directly with standard T-A series spade drill bodies\u003c\/li\u003e\n  \u003cli\u003e0.1875 inch insert thickness maintains rigidity during interrupted cuts\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 holders.

Before changing an insert, confirm the machine spindle is fully stopped and locked out per applicable machine guarding and lockout\/tagout procedures. Seat the insert fully against the holder pocket faces before tightening the clamping screw, and inspect the seat for chips or debris that could affect insert seating and runout. Consult the T-A series holder documentation for recommended clamping torque and coolant delivery settings appropriate to the holder body in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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\u003eMaterial Grade\u003c\/strong\u003e: T15\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\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\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\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: 152A-25\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51736735088946,"sku":"152A-25","price":74.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a406c7579822f46ebe9afe29bd9961f_1820ce68-4376-4e54-b823-a38a2792d1bc.jpg?v=1788779617","url":"https:\/\/voomisupply.com\/products\/allied-machine-152a-25-spade-drill-insert-63-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
