Coated with TiAlN and TiN via a PVD process, it is engineered for interrupted and continuous milling operations where thermal resistance and edge retention are critical. The insert features a neutral rake angle, a T-Land cutting edge style, and 3 usable cutting edges per insert. With an inscribed circle of 0.5 inches and a corner radius of 0.047 inches, it suits moderate depth-of-cut applications in production milling environments. Licensed machinists and CNC tooling technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, making it a versatile option across general machining and aerospace-type applications. It is designed for use in wedge-clamp style toolholders and is compatible with cutter series R220.17-22 and R220.47. Typical applications include face milling and shoulder milling on CNC machining centers in both production and job-shop environments. The neutral hand designation means it fits standard right-hand and left-hand configurations without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain substrate for high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN and TiN dual-layer PVD coating for thermal protection and extended tool life\u003c\/li\u003e\n  \u003cli\u003e3 cutting edges per insert reduces per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eT-Land cutting edge style provides added edge strength for interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral rake and neutral hand — fits standard wedge-clamp toolholders without modification\u003c\/li\u003e\n  \u003cli\u003eBroad material compatibility: steel, cast iron, superalloys, titanium, and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with SECO cutter series R220.17-22 and R220.47 using wedge-clamp insert holding.

Always power down and lock out the spindle before changing inserts. Seat the insert fully against the pocket locating surfaces before engaging the wedge clamp, and verify clamp torque per the toolholder manufacturer's specifications. Inspect the insert pocket for chips or debris before seating a new insert to prevent micro-fractures at the cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPUN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: TPUN220412T\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide (Fine Grain)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: F40M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (0.5000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inches (0.0472 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 45\/64 inches (0.7031 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 45\/64 inches (0.7031 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.7031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.7031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 220412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TPUN-22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02505955\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557862310194,"sku":"02505955","price":312.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/97a2cd49a1c315eaf403e72d5bf683a6.jpg?v=1786396718","url":"https:\/\/voomisupply.com\/products\/seco-02505955-tpun220412t-f40m-carbide-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
