Manufactured from cobalt, this insert measures 2-29\/32 inches in diameter and features a 144-degree point angle for aggressive, accurate entry into tough workpiece materials. It belongs to the GEN2 T-A series and carries an AM200 PVD coating that extends tool life by reducing friction and heat buildup during cutting. The insert is 0.4375 inches thick and fits Seat Size 5 holders. It is intended for installation by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling into steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A platform is designed for indexable spade drilling operations where consistent geometry and repeatable performance are required across medium-to-large diameter hole sizes. The 144-degree point angle reduces thrust and improves chip formation when entering difficult-to-machine alloys. It is commonly used in vertical machining centers, horizontal mills, and lathe drilling operations where coolant-fed toolholders are employed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt substrate provides elevated heat resistance and wear durability in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e144-degree point angle optimized for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eGEN2 T-A series design for consistent seating and repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eSeat Size 5 compatibility matches a broad range of standard GEN2 T-A spade drill holders\u003c\/li\u003e\n  \u003cli\u003e0.4375-inch insert thickness maintains rigidity across the full 2-29\/32-inch cutting diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Seat Size 5 GEN2 T-A spade drill holders.

Before indexing or replacing the insert, ensure the machine spindle is fully stopped and the tool is secured in a vise or holder. Use the appropriate torque wrench and insert screw specified by the holder manufacturer — do not overtighten, as this can damage the insert seat. Verify insert seating and runout before returning the holder to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2-29\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 144 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eSeries\u003c\/strong\u003e: GEN2 T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys and Titanium, 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\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: 455H-0229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51750668796210,"sku":"455H-0229","price":144.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50e4fe7d4c6435aa1f2e31eae6182553_98427147-aa9b-482c-9b60-514f392856c8.jpg?v=1788918152","url":"https:\/\/voomisupply.com\/products\/allied-machine-455h-0229-spade-drill-insert-2-29-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
