Part of the GEN2 T-A series, this insert measures 2-11\/16 inches in diameter and seats into a Size 5 holder. It features a 144-degree point angle and an AM200 PVD coating that extends tool life when drilling through tough workpiece materials. The 0.4375-inch thickness provides rigidity during deep-hole drilling operations. Licensed machinists and tool-and-die professionals working with CNC lathes or machining centers are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production drilling in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It fits the GEN2 T-A spade drill system and is appropriate for both roughing and precision boring operations where a replaceable insert design reduces downtime compared to solid-shank tooling. The AM200 PVD coating performs well under high cutting speeds and reduces built-up edge on difficult alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-11\/16 inch diameter, Seat Size 5, compatible with GEN2 T-A spade drill holders\u003c\/li\u003e\n\u003cli\u003e144-degree point angle for self-centering entry and reduced thrust in hard materials\u003c\/li\u003e\n\u003cli\u003eCobalt substrate provides toughness and heat resistance beyond standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eAM200 PVD coating extends wear life on steel, stainless steel, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n\u003cli\u003e0.4375 inch insert thickness delivers rigidity in deep-hole and interrupted-cut applications\u003c\/li\u003e\n\u003cli\u003eSold individually, allowing single-insert replacement without purchasing a complete tool assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ALLIED MACHINE AND ENGINEERING GEN2 T-A series spade drill holders at Seat Size 5.

Ensure the machine spindle is fully stopped and the tool is secured in a vise or holder fixture before swapping inserts. Inspect the seat pocket for chips or debris before seating the insert, as contamination can cause runout and premature edge failure. Follow applicable shop safety protocols and machine manufacturer guidelines during tool changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 144 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GEN2 T-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AM200\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: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 455H-0222\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730135974194,"sku":"455H-0222","price":144.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50e4fe7d4c6435aa1f2e31eae6182553_75beec22-ca3d-404d-9ec4-483ff2f1c249.jpg?v=1788712369","url":"https:\/\/voomisupply.com\/products\/allied-machine-455h-0222-spade-drill-insert-2-11-16-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
