Carrying the ANSI and ISO 13399 designation HM390 TDKT 150516-PDR IC830, this triangular insert features three helical cutting edges and a positive rake geometry. The IC830 grade uses a PVD-applied AlTiN and TiN Sumotec coating that provides wear resistance and thermal stability at the cutting edge. With a 0.2290 inch thickness, a 0.6460 inch width and length, and a 0.0630 inch corner radius, the insert is engineered for demanding metal removal in steel and difficult-to-machine alloys. It is installed by licensed machinists and CNC machine operators in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is applied in milling operations targeting steel, stainless steel, superalloys, and titanium. The PDR chip breaker geometry supports positive cutting action suited for roughing and semi-finishing passes. The right-hand cutting orientation and screw-holding method are standard for HM390-15 cutter bodies. Typical applications include shoulder milling, face milling, and helical interpolation on CNC machining centers. The maximum depth of cut reaches 0.4920 inches (12.50 mm), making it effective for moderate-to-aggressive material removal in production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC830 grade with PVD-applied AlTiN and TiN Sumotec coating for extended tool life in steel and superalloys\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape with 3 cutting edges and 60-degree included angle maximizes edge utilization per insert\u003c\/li\u003e\n\u003cli\u003eHelical cutting edge style with positive rake reduces cutting forces and improves surface finish\u003c\/li\u003e\n\u003cli\u003ePDR chip breaker controls chip evacuation during steel, stainless steel, and titanium milling\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.4920 inches (12.50 mm) supports aggressive material removal rates\u003c\/li\u003e\n\u003cli\u003eScrew-held, single-sided, right-hand insert with 15-degree relief angle for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HM390-15 series cutter bodies.

Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key driver specified for the cutter body screw to seat the insert flush against the pocket without rocking. Inspect the pocket seating surfaces for chips or burrs before installing a new insert to ensure proper contact and avoid premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eSeries\u003c\/strong\u003e: HELI3MILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: HM390 TDKT 150516-PDR IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: HM390 TDKT 150516-PDR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: Sumotec PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 150516\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2290 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.6460 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6460 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\u003eCorner Radius\u003c\/strong\u003e: 0.0630 inches (1.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4920 inches (12.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.4920 inches\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PDR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: HM390-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5666725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732730904882,"sku":"5666725","price":311.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bcbd395f2c07f92c6ac6776a7ea0c52.jpg?v=1788746107","url":"https:\/\/voomisupply.com\/products\/iscar-5666725-milling-insert-hm390-tdkt-150516-pdr-ic830","provider":"Voomi Supply","version":"1.0","type":"link"}
