With a 27\/64 inch cutting diameter, a 132-degree point angle, and a TiAlN PVD coating, this insert delivers reliable cutting performance across a range of workpiece materials. It fits the T-A series holder system using a Seat Size Y configuration. Machining professionals and toolroom technicians install this insert as a replaceable cutting element within a T-A spade drill body, eliminating the need to replace the entire drill assembly.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling operations in stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. It is used in CNC machining centers, lathes, and manual drill presses in both production and job-shop environments. The TiAlN coating provides thermal resistance, making it appropriate for dry or minimal-lubrication cutting strategies common in high-speed and hard-material applications. The C2 (K20) carbide grade balances wear resistance and toughness for these varied material types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/64 inch cutting diameter in T-A series Seat Size Y format\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction, Manufacturer Grade C2 (K20), for wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating enhances thermal stability and tool life in stainless steel, cast iron, super-alloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle for aggressive entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eReplaceable insert design preserves the drill body and reduces per-hole tooling cost\u003c\/li\u003e\n  \u003cli\u003e0.0938 inch insert thickness for consistent seating in T-A compatible holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Allied Machine and Engineering T-A series spade drill holders accepting Seat Size Y inserts.

Before changing the insert, confirm the spindle is fully stopped, the machine is powered down, and the tool is secured in a vise or holder to prevent rotation. Use the appropriate T-A insert wrench or torx key specified for the holder to seat the insert flush against the pocket; do not overtighten by hand estimation alone. Inspect the holder pocket for chips or damage before seating the new insert to ensure accurate cutting geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 27\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: Y\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: C2 (K20)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Cast Iron, Non-Ferrous Metal, Super-alloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 1C2YA-.421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51749869814066,"sku":"1C2YA-.421","price":80.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9eb5f1878e7666230c52f8d05dd1af81_95a9efe5-e749-4342-a53c-2bf2c4ee0834.jpg?v=1788911483","url":"https:\/\/voomisupply.com\/products\/allied-machine-1c2ya-421-spade-drill-insert-27-64-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
