Measuring 25\/32 inches in diameter with a 132-degree point angle, this insert is manufactured from T15 cobalt high-speed steel and features a TiN (titanium nitride) PVD coating for extended tool life and reduced friction. It is sized for a Seat Size 1 holder and belongs to the T-A series, a widely used platform in production drilling environments. Machinists, tool-and-die makers, and CNC operators install this insert as a replaceable cutting element in compatible T-A series spade drill bodies.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium — covering ISO material groups P, M, K, and S. It is a common choice in job shops and production facilities where a single insert platform must handle diverse workpiece materials. The fractional inch sizing fits standard imperial-specification T-A series holders, making it straightforward to incorporate into existing setups without toolholder changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/32 inch diameter with 132-degree point angle for positive cutting entry and minimal thrust\u003c\/li\u003e\n  \u003cli\u003eT15 cobalt high-speed steel substrate provides toughness and heat resistance in interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eTiN PVD coating reduces built-up edge and extends insert service life across multiple regrind cycles\u003c\/li\u003e\n  \u003cli\u003eSeat Size 1 fits standard T-A series spade drill bodies without modification\u003c\/li\u003e\n  \u003cli\u003eRated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eFractional inch system sizing for compatibility with imperial-specification tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A series Seat Size 1 spade drill holders.

Before seating the insert, ensure the drill body pocket and clamping surfaces are clean and free of chips or debris, as contamination will cause insert misalignment and premature failure. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as this can crack the insert. Verify insert seating and runout before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 25\/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 Material\u003c\/strong\u003e: Cobalt High-Speed Steel\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: TiN (Titanium Nitride)\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\u003eSeat Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 151T-0025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51749118673202,"sku":"151T-0025","price":56.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f187fc3030457129e30d01bc96d6a930.jpg?v=1788902290","url":"https:\/\/voomisupply.com\/products\/allied-machine-151t-0025-spade-drill-insert-25-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
