Built to the T-A Series standard, this insert measures 21\/32 inches in diameter with a 132-degree point angle and a 0.125-inch thickness. A PVD-applied TiN coating reduces friction and extends cutting edge life under heavy feed rates. Seat Size 0 positions this insert for smaller-diameter T-A Series blade holders. Machinists and tool-room technicians working in production and job-shop environments rely on this insert for consistent, repeatable hole geometry.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO material classifications P, M, K, S, and H. It is appropriate for CNC machining centers, lathes with live tooling, and manual drill presses where spade-drill tooling is specified. The cobalt substrate provides thermal resistance when cutting work-hardening alloys such as stainless steel and nickel-based super-alloys, where high-speed steel inserts lose edge integrity more quickly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21\/32-inch cutting diameter with 132-degree point angle for aggressive chip formation and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eCobalt substrate delivers elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating lowers cutting friction and improves tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eT-A Series, Seat Size 0 — indexes directly into compatible Allied T-A blade holders without shimming\u003c\/li\u003e\n  \u003cli\u003e0.125-inch insert thickness provides a stable seating interface under high feed loads\u003c\/li\u003e\n  \u003cli\u003eCompatible with ISO workpiece material groups P, M, K, S, and H for broad application coverage\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 Seat Size 0 spade drill blade holders.

Inspect the blade holder pocket and clamping screw for wear or damage before seating a new insert. Torque the clamping screw to the blade holder specification provided by the tool manufacturer. Do not operate the insert beyond the feed and speed parameters published in the Allied T-A Series application guide.\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\u003ePoint Angle\u003c\/strong\u003e: 132 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 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\u003eInsert Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN\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: Steel, Stainless Steel, Cast Iron, Super-alloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Material Codes\u003c\/strong\u003e: P, M, K, S, H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 180T-0021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51730100420914,"sku":"180T-0021","price":56.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08b2c2967ba0da65a25e5f0bea0e1fb_3d4007ea-4885-4181-9332-c760aaf54dce.jpg?v=1788711761","url":"https:\/\/voomisupply.com\/products\/allied-machine-180t-0021-spade-drill-insert-21-32-in-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
