Manufactured in the GEN2 T-A series, this insert features a 132-degree point angle and carries an AM200 PVD coating for extended tool life and reduced built-up edge. At 25\/64 inches in diameter with a Seat Size Y designation, it seats directly into compatible T-A spade drill holders. The cobalt substrate provides toughness and heat resistance at elevated cutting speeds, making it well-suited for demanding production drilling environments. Installation and tool management are handled by machinists and CNC tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThe 45YH-.390 insert is rated for use across a broad range of workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, corresponding to ISO material classifications P, M, K, S, and H. This versatility makes it appropriate for job shops, production machining cells, and aerospace or heavy-industry applications where a single insert geometry must handle multiple material types. The GEN2 T-A series is a widely used indexable spade drilling platform, and this insert is sized for standard Seat Size Y holders in that system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e25\/64 inch diameter with Seat Size Y for direct drop-in to compatible T-A holders\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle reduces thrust and improves chip formation on entry\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate delivers heat resistance and toughness at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eAM200 PVD coating extends cutting edge life and resists built-up edge\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eGEN2 T-A series geometry for consistent, repeatable hole quality\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 Seat Size Y insert.

Ensure the holder is fully de-energized and the spindle is locked or at a complete stop before indexing or replacing inserts. Use the correct torx or hex key as specified by the holder design to secure the insert clamp screw. Inspect the insert seat for chips or contamination before seating a new insert to ensure proper support and runout performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 25\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: Y\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 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: 0.0938 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  \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: 45YH-.390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51732894220594,"sku":"45YH-.390","price":67.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3113cc6ac73e909b41bae14379d0f9c4_df1a6eb5-e5c1-4f38-a56e-8d31868433a7.jpg?v=1788748282","url":"https:\/\/voomisupply.com\/products\/allied-machine-45yh-390-spade-drill-insert-25-64-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
