This insert measures 1-7\/8 inches in diameter and features a 132-degree point angle, making it suited for drilling operations that require a moderate entry geometry. Constructed from M4-grade high speed steel with a PVD-applied TiN coating, the insert offers wear resistance and extended tool life in demanding cutting applications. Seat Size 3 corresponds to the matching holder size required for proper installation. Licensed machinists and toolroom technicians are the primary installers of this insert type.\u003c\/p\u003e\n\u003cp\u003eThis spade drill insert is part of the GEN2 T-A series from Allied Machine and Engineering. It is intended for use in metalworking and machining operations, including production drilling in CNC machining centers, lathes with live tooling, and manual drill presses where spade-style tooling is appropriate. The 0.25-inch blade thickness and fractional-inch sizing system make this insert suitable for shops working to inch-based print tolerances. Primary workpiece material categories include steel, cast iron, and non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-7\/8 inch diameter with Seat Size 3 holder compatibility\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle for general-purpose drilling geometry\u003c\/li\u003e\n  \u003cli\u003eM4-grade high speed steel construction for toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating applied for extended insert life and reduced friction\u003c\/li\u003e\n  \u003cli\u003eGEN2 T-A series designation for compatibility with Allied T-A holder system\u003c\/li\u003e\n  \u003cli\u003eRated for use in steel, cast iron, and non-ferrous metal workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Allied Machine and Engineering GEN2 T-A series spade drill holders requiring a Seat Size 3 insert.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully and evenly in the holder pocket and secure it with the appropriate fastener to the holder manufacturer's specification. Inspect the seating surface and holder pocket for chips or debris before each insert change to prevent runout and premature insert failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1-7\/8 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GEN2 T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 433T-0128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51747680190770,"sku":"433T-0128","price":75.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fc2c2a2728e0700b5155f0fba022a54.jpg?v=1788884448","url":"https:\/\/voomisupply.com\/products\/allied-machine-433t-0128-spade-drill-insert-1-7-8in-132deg-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
