Part of the T-A Series, this insert measures 21\/32 inches in diameter and features a 132-degree point angle for accurate entry and reduced thrust. The TiCN (Titanium Carbonitride) coating is applied via PVD process, providing increased surface hardness and improved wear resistance. At 0.125 inches thick and weighing 0.1 pounds, the insert fits a Seat Size 0 holder. Licensed machinists and tool-and-die professionals are the primary installers of this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling into a broad range of workpiece materials including steel, stainless steel, cast iron, super-alloys, and titanium. The T-A Series platform is a widely adopted indexable spade drill system used in CNC machining centers, manual lathes, and drill presses across production, job shop, and maintenance environments. The 132-degree point geometry performs well in interrupted cuts and on curved or angled entry surfaces common in those materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21\/32 inch diameter, Seat Size 0 for T-A Series holders\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle for accurate entry and reduced axial thrust\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate provides toughness in tough and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiCN PVD coating increases surface hardness and extends tool life\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, and titanium (ISO material codes P, M, K, S)\u003c\/li\u003e\n  \u003cli\u003e0.125 inch insert thickness for Seat Size 0 compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for T-A Series Seat Size 0 spade drill holders.

Ensure the machine spindle is fully stopped and locked out before seating or removing the insert. Use the correct insert screw and torque driver specified by the holder manufacturer — do not substitute fasteners. Inspect the holder seat for debris or wear before installing a new insert, as a damaged seat will affect runout and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Size\u003c\/strong\u003e: 0\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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium\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: 150N-0021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51736478122290,"sku":"150N-0021","price":59.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cc61a86581c7c237cddd3de1d83057e_1b4e3d5f-0036-4676-8359-efab0c71b059.jpg?v=1788778166","url":"https:\/\/voomisupply.com\/products\/allied-machine-150n-0021-spade-drill-insert-21-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
