Built to the GEN2 T-A series specification, this insert features a 144-degree point angle and an AM200 PVD coating that extends tool life when cutting through abrasive and hard-to-machine materials. The insert measures 3-1\/8 inches in diameter with a seat size 6 designation, matching the corresponding GEN2 T-A spade drill holder. Machinists and tool-room technicians select this insert when they need consistent, repeatable performance in production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for use across a broad range of primary workpiece materials, including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is suited to CNC machining centers, lathes with live tooling, and dedicated drill presses in both job-shop and production environments. The GEN2 T-A system indexes the insert into a replaceable-tip holder, eliminating the need to replace the full drill body and reducing per-hole tooling cost in high-volume runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-1\/8 inch diameter with seat size 6 for precise holder fitment in the GEN2 T-A system\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate delivers elevated heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating classification improves lubricity and reduces built-up edge on ferrous and exotic materials\u003c\/li\u003e\n  \u003cli\u003e144-degree point angle geometry suited to flat-bottom entry and exit conditions\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, titanium, and hard material workpieces\u003c\/li\u003e\n  \u003cli\u003e0.4375-inch thickness maintains rigidity across the full diameter during chip evacuation\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 seat size 6 spade drill holders.

Power down and lock out the spindle before seating or removing the insert. Use the manufacturer-specified torx or hex key to secure the insert screw to the holder; do not substitute non-rated fasteners. Inspect the holder seat for chips, burrs, or wear before each insert change to ensure proper seating and runout control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 144 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\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\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  \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: 456H-0304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51748737843506,"sku":"456H-0304","price":162.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc670b5a7e78abdbb19f06aba5b6e73c_3e90be08-78b3-44ce-84a1-cf6ba5c81488.jpg?v=1788897548","url":"https:\/\/voomisupply.com\/products\/allied-machine-456h-0304-spade-drill-insert-3-1-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
