Carrying the IC882 grade designation, this insert features a multilayer PVD coating that combines AlTiN, TiAlSiN, and TiSiN layers to deliver hardness and heat resistance at the cutting edge. The triangular TDKT insert style provides 3 usable cutting edges per insert, and the positive rake geometry reduces cutting forces during machining. At 5.85 mm thick with a 0.80 mm corner radius, the 3309395 is built for demanding cuts in difficult-to-machine materials. Licensed HVAC techs, plumbers, and electricians will not typically install this part — it is used by machinists and CNC operators in metalworking environments.\u003c\/p\u003e\u003cp\u003eThe ISCAR 3309395 belongs to the HELI3MILL series and is compatible with HM390-15 cutter bodies. Its primary application is milling stainless steel, superalloys, and titanium — material groups M and S under ISO classification. The PDR chip breaker geometry supports controlled chip evacuation during moderate to heavy cuts. With a maximum depth of cut of 13.00 mm, this insert suits roughing and semi-finishing passes on difficult workpiece materials in both production shop and job-shop environments. The right-hand cutting orientation and screw-in holding method make setup straightforward on compatible toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC882 grade with multilayer PVD coating: AlTiN, TiAlSiN, and TiSiN for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape with 3 cutting edges per insert for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003ePositive rake and helical cutting edge style reduce cutting forces on stainless steel and superalloys\u003c\/li\u003e\n\u003cli\u003ePDR chip breaker geometry supports reliable chip control during milling\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 13.00 mm suits roughing and semi-finishing operations\u003c\/li\u003e\n\u003cli\u003eSingle-sided, right-hand insert with screw holding method 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 in the ISCAR HELI3MILL platform.

Power down and lock out the machine spindle before seating or removing inserts. Use the manufacturer-specified torx or hex key to drive the clamping screw to the recommended seating feel — do not overtighten, as solid carbide inserts are brittle and can crack under excess clamp force. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and runout.\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\u003eManufacturer Grade\u003c\/strong\u003e: IC882\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, TiAlSiN, TiSiN (PVD Process)\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\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\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5.85 mm (0.2300 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 11.40 mm (0.4490 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 16.70 mm (0.6580 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 13.00 mm (0.5120 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: HM390-15\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: 3309395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748633575730,"sku":"3309395","price":63.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac331d400d73ef9e82cddd516c21f5dc.jpg?v=1788895973","url":"https:\/\/voomisupply.com\/products\/iscar-3309395-milling-insert-ic882-solid-carbide-heli3mill","provider":"Voomi Supply","version":"1.0","type":"link"}
