Manufactured from submicron-grade carbide and coated with a multilayer PVD system of TiAlN, AlTiN, and TiN, it delivers wear resistance across a broad range of workpiece materials. The insert measures 0.307 inches in both length and width, with a thickness of 0.124 inches and a corner radius of 0.0197 inches. With three cutting edges, a positive rake geometry, and a helical cutting-edge style, this insert reduces cutting forces and supports stable chip evacuation in demanding milling operations. It is seated and held by screw-clamping in compatible HM390-07 cutter bodies.\u003c\/p\u003e\n\u003cp\u003eThe 5607773 insert is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. It is appropriate for both roughing and finishing passes where a maximum depth of cut of 0.197 inches is acceptable. The right-hand, single-sided configuration and PCTR chip breaker geometry make it a practical choice for high-feed shoulder milling operations in production machining environments. Machinists and tooling technicians working on CNC mills and machining centers in job shops, aerospace, and general metalworking applications will find this insert applicable to a wide range of setups requiring controlled chip formation on difficult materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide substrate with IC808 grade designation for toughness and edge stability\u003c\/li\u003e\n  \u003cli\u003eMultilayer PVD coating — TiAlN, AlTiN, and TiN — for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTriangular shape with three cutting edges maximizes insert utilization and reduces per-edge cost\u003c\/li\u003e\n  \u003cli\u003ePositive rake, helical cutting edge reduces cutting forces and vibration\u003c\/li\u003e\n  \u003cli\u003ePCTR chip breaker geometry promotes efficient chip control across steel and hard materials\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.197 inches with a 7-degree relief angle for clearance in shoulder milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ISCAR HM390-07 series cutter bodies as part of the HELI3MILL system.

Ensure the cutter body is removed from the spindle or the machine is in a locked-out, de-energized state before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the manufacturer-specified seating without over-torquing, which can crack the insert or damage the pocket. Inspect the insert pocket for chips or debris and confirm the insert is fully seated and stable before returning the tool to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCKT\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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC808\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, AlTiN, 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: PCTR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0197 inches (0.51 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.124 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.307 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.307 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2283 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.197 inches (5.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 0703\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: HM390-07\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HELI3MILL\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: HM390 TCKT 0703PCTR IC808\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: HM390 TCKT 0703PCTR\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: 0.529 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: 5607773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51754685661490,"sku":"5607773","price":250.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63c4fe0a7e0c62f2b1c86661afd3d5e4.jpg?v=1788947813","url":"https:\/\/voomisupply.com\/products\/iscar-5607773-milling-insert-hm390-tckt-0703pctr-ic808","provider":"Voomi Supply","version":"1.0","type":"link"}
