It measures 2-3\/8 inches in diameter and belongs to the GEN2 T-A series, a well-established platform for replaceable-insert spade drilling. The insert is manufactured from M4-grade high speed steel and features a physical vapor deposition (PVD) titanium nitride (TiN) coating for improved wear resistance and tool life. The 132-degree point angle suits general-purpose drilling applications where controlled entry and clean hole geometry are required. At 0.3125 inches thick, the insert seats into a Size 4 holder for secure, repeatable positioning.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for use in machining environments where operators are drilling into steel, cast iron, or non-ferrous metals. It fits into spade drill holder systems accepting a Size 4 seat, making it a working component in both production and maintenance machining contexts. The GEN2 T-A series is a common platform in job shops, manufacturing facilities, and heavy equipment maintenance operations. Installation and tool management is typically handled by machinists, toolroom technicians, or maintenance mechanics familiar with indexable drilling systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-3\/8 inch diameter for large-hole spade drilling without solid-drill weight or cost\u003c\/li\u003e\n  \u003cli\u003eM4 high speed steel construction for toughness and resistance to chipping under interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eTiN PVD coating extends cutting edge life and reduces built-up edge on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle provides a good balance of centering ability and cutting force distribution\u003c\/li\u003e\n  \u003cli\u003eSize 4 seat ensures positive insert location and repeatable runout when used with compatible holders\u003c\/li\u003e\n  \u003cli\u003eFractional inch sizing system for straightforward specification in inch-standard machine shops\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holders accepting a Size 4 insert seat.

Verify that the holder seat and clamping surfaces are clean and free of chips before seating the insert, as debris under the insert can affect runout and lead to premature failure. Use the holder manufacturer's recommended torque procedure for the clamping screw — refer to the GEN2 T-A holder documentation for specifics. Inspect the seating pocket for wear or damage each time the insert is changed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2-3\/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: 4\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\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: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GEN2 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, Cast Iron, Non-Ferrous Metal\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: 434T-0212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51747684286770,"sku":"434T-0212","price":83.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5555d23036edac2252ae7910015875a1.jpg?v=1788884493","url":"https:\/\/voomisupply.com\/products\/allied-machine-434t-0212-spade-drill-insert-2-3-8-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
