Carrying the ANSI designation HM390 TPKT 100316PDR IC830, this triangular insert features a positive rake geometry and a helical cutting edge style that promotes smooth chip evacuation and reduced cutting forces. The IC830 grade is applied with an AlTiN and TiN PVD coating using ISCAR Sumotec PVD technology, providing wear resistance and thermal stability during high-productivity milling. With a corner radius of 1.60 mm (0.0630 inch) and a PDR chip breaker, the insert is suited to finishing and semi-finishing passes in demanding materials. Installation is performed by qualified machinists or tooling technicians using a screw-clamp holding method.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in the HM390-10 cutter series, specifically compatible with HM390 TPKT toolholders. Primary workpiece material applications include steel (P), stainless steel (M), superalloys, and titanium (S). The right-hand cutting geometry and positive rake angle make this insert well suited to both roughing and finishing strategies in CNC milling centers where consistent chip control and extended tool life in difficult-to-machine alloys are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC830 grade with AlTiN and TiN PVD Sumotec coating for wear resistance in steel, stainless, and superalloy applications\u003c\/li\u003e\n\u003cli\u003ePositive rake, helical cutting edge style reduces cutting forces and improves surface finish\u003c\/li\u003e\n\u003cli\u003ePDR chip breaker geometry controls chip flow during semi-finishing and finishing cuts\u003c\/li\u003e\n\u003cli\u003e3 cutting edges per insert on a single-sided triangular body maximizes tool economy\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 8.00 mm (0.3150 inch) supports productive material removal rates\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards for broad toolholder compatibility within the HM390-10 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HM390-10 series milling cutters accepting HM390 TPKT style inserts.

Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Seat the insert fully into the pocket and tighten the clamping screw to the torque specification provided in the toolholder documentation — do not use impact tools on the clamping screw. Inspect the insert pocket for chips or damage before seating a new insert to prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPKT\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 and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (Sumotec PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.60 mm (0.0630 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 7.50 mm (0.2953 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.85 mm (0.1520 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10.90 mm (0.4290 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4290 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 8.00 mm (0.3150 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\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: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: HM390-10\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\u003eWeight\u003c\/strong\u003e: 0.01 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: 5667769\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733485093170,"sku":"5667769","price":278.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23342e182556b54122c5995c1ce5a607.jpg?v=1788755806","url":"https:\/\/voomisupply.com\/products\/iscar-5667769-milling-insert-ic830-solid-carbide-triangle","provider":"Voomi Supply","version":"1.0","type":"link"}
