Part of the T-A series, this insert features a 45.5 mm cutting diameter and a Seat Size 3 designation for proper holder fitment. The TiAlN PVD coating provides thermal resistance and surface hardness, extending tool life in abrasive and heat-generating cuts. The 90-degree point angle supports aggressive material entry with controlled chip formation. At 0.25 inches thickness and 0.1 pounds, the insert is a direct drop-in replacement for worn T-A series seats. Machinists and tool crib technicians managing high-volume or specialty drilling programs will find this insert suited for production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for use in CNC machining centers, horizontal boring mills, and manual drill presses equipped with T-A series spade drill holders. Its primary workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium, making it a versatile choice across aerospace, energy, and general metalworking operations. The T15 material grade cobalt substrate maintains hardness at elevated cutting temperatures, making it especially effective when drilling interrupted cuts or hard-to-machine alloys. Shops handling production runs across mixed material types will find this insert compatible with a broad range of workpiece specifications without changing insert platforms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45.5 mm cutting diameter with Seat Size 3 for T-A series holder compatibility\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate, T15 material grade for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating reduces thermal buildup and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e90-degree point angle for controlled entry and reduced thrust in production drilling\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, and titanium workpieces\u003c\/li\u003e\n  \u003cli\u003e0.25 inch insert thickness for rigid seating in standard T-A holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A series Seat Size 3 spade drill holders.

Ensure the holder and machine spindle are fully de-energized and locked out before changing inserts. Seat the insert firmly and verify screw torque per the holder manufacturer's tooling documentation before resuming cutting operations. Inspect the seat pocket for chips or damage before installing a new insert to avoid premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 45.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 3\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\u003ePoint Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 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: 153A-45.5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51731908165938,"sku":"153A-45.5","price":86.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/052c8a24db185ab5db4fd6cc0f81cf60.jpg?v=1788736418","url":"https:\/\/voomisupply.com\/products\/allied-153a-45-5-spade-drill-insert-45-5mm-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
