It features a 132-degree point angle and a TiAlN (titanium aluminum nitride) PVD coating that resists heat and wear during aggressive cutting operations. Sized at 7\/8 inch in diameter with a 0.1563 inch thickness, this insert fits Seat Size 1 holders in the T-A series system. It is intended for use by machinists and metalworking professionals who require consistent hole quality and extended tool life in production drilling environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for industrial drilling applications targeting steel and hard material workpieces in both job shop and production settings. The T-A series spade drill system is a modular platform where the insert seats into a reusable holder, allowing fast insert changes without pulling the holder from the spindle. The C5 (P40) carbide grade makes this insert appropriate for general-purpose steel cutting, including roughing passes and through-hole drilling in ferrous metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction at manufacturer grade C5 (P40) for durability in steel and hard material applications\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating provides thermal resistance and extended cutting life\u003c\/li\u003e\n\u003cli\u003e132-degree point angle reduces thrust and improves chip formation on entry\u003c\/li\u003e\n\u003cli\u003e7\/8 inch diameter with 0.1563 inch thickness engineered for Seat Size 1 T-A series holders\u003c\/li\u003e\n\u003cli\u003eModular insert design enables quick changeover without removing the holder from the machine\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Seat Size 1 holders in the Allied Machine and Engineering T-A spade drill series.

Ensure the spindle is fully stopped and the machine is locked out before seating or removing the insert. Use the appropriate torque wrench and insert screws specified for the T-A series holder to secure the insert properly. Inspect the insert seat for chips or debris before installation to ensure proper seating and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 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: 1\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: C5 (P40)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Hard Material\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: 1C51A-0028\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730836390194,"sku":"1C51A-0028","price":91.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/018dd13e89e27846da59559c85267889_6d9aef90-5910-4d97-8220-1a8e795b7b7c.jpg?v=1788723620","url":"https:\/\/voomisupply.com\/products\/allied-machine-1c51a-0028-spade-drill-insert-7-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
