Part of the T-A series, this insert features a 132-degree point angle and a titanium aluminum nitride (TiAlN) PVD coating that extends tool life by reducing heat buildup and wear at the cutting edge. With a seat size of 1 and a 27\/32 inch diameter, it is intended for use in compatible T-A spade drill holders. Machinists and tool-and-die professionals install this insert as the cutting element in modular spade drilling systems on CNC machining centers and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium. Its TiAlN coating and cobalt substrate make it a practical choice when cutting harder ferrous and exotic materials where uncoated high-speed steel inserts would wear prematurely. Typical applications include production drilling in job shops, aerospace component manufacturing, and heavy equipment fabrication where consistent hole geometry and extended insert life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/32 inch cutting diameter with seat size 1 for use in T-A series spade drill holders\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness and heat resistance beyond standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating reduces friction and extends cutting life in ferrous and exotic materials\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle suited for drilling steel, stainless steel, cast iron, and titanium alloys\u003c\/li\u003e\n  \u003cli\u003e0.1563 inch insert thickness for proper seating and rigid cutting geometry\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 changing the insert, ensure the machine is powered down, the spindle is locked, and all stored energy is released. Seat the insert firmly in the holder pocket and secure with the retaining screw using the correct driver to avoid stripping. Inspect the holder seat for chips or wear before installing a new insert, as a damaged seat will affect hole accuracy and insert retention.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 27\/32 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\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\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\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys and 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\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: 151A-0027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51755388404018,"sku":"151A-0027","price":65.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/018dd13e89e27846da59559c85267889_e8d63bb9-0b92-4359-9a2c-3c2a0667b842.jpg?v=1788954429","url":"https:\/\/voomisupply.com\/products\/allied-machine-151a-0027-spade-drill-insert-27-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
