Built to ANSI and ISO 13399 standards, this triangular insert carries the IC830 grade designation with an AlTiN plus TiN PVD coating applied through ISCAR Sumotec PVD technology. It measures 0.5980 inches in length and width, 0.2300 inches thick, and features a 0.1260-inch corner radius. Three cutting edges are available per insert, each with a helical cutting edge style and positive rake geometry. The PDR chip breaker controls chip flow effectively across the supported material range. Machinists and CNC operators working in job shops and production environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling steel, stainless steel, superalloys, and titanium — material application codes P, M, and S. The positive rake and helical edge reduce cutting forces, making it well suited for finishing and semi-finishing passes on difficult-to-machine materials. It is sized to the HM390-15 cutter series and carries the ANSI code HM390 TDKT 150532-PDR IC830 along with ISO code HM390 TDKT 150532-PDR. The right-hand configuration supports standard climb and conventional milling setups. Maximum depth of cut is 0.4720 inches (12.00 mm). Effective cutting edge length is also 0.4720 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC830 grade with Sumotec AlTiN plus TiN PVD coating for heat and wear resistance in steel and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape with 3 cutting edges maximizes cost-per-edge value\u003c\/li\u003e\n  \u003cli\u003ePDR chip breaker geometry designed for positive-rake, free-cutting action\u003c\/li\u003e\n  \u003cli\u003eHelical cutting edge style reduces radial cutting forces and vibration\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.4720 inches (12.00 mm) supports aggressive material removal rates\u003c\/li\u003e\n  \u003cli\u003eScrew-held, single-sided insert with right-hand orientation for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards for tooling interchangeability documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in HM390-15 series milling cutters.

Fully de-energize and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw and ensure the insert seat and pocket are clean and free of chips before seating the new insert. Reuse of damaged or chipped inserts is not recommended, as it can cause premature cutter body wear or insert ejection during cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TDKT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\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: IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN plus TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (Sumotec)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PDR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1260 inches (3.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.4488 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4720 inches (12.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.4720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 150532\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: HM390-15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELI3MILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5666731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738377683250,"sku":"5666731","price":312.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b633b403160d71508a2e823fbc45d17.jpg?v=1788798826","url":"https:\/\/voomisupply.com\/products\/iscar-5666731-milling-insert-ic830-solid-carbide-triangle","provider":"Voomi Supply","version":"1.0","type":"link"}
