Coated with TiAlN and TiN via a PVD process, the IC907 grade delivers wear resistance and thermal stability across a range of workpiece materials. The triangular insert geometry features a 60-degree included angle, a positive rake, and an 11-degree relief angle, which together reduce cutting forces and support clean chip formation. Installed by machinists and CNC operators, this insert is a screw-held design suited to high-production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations involving hardened steels, stainless steels, heat-resistant superalloys, cast iron, non-ferrous metals, and general steel workpieces, as indicated by its primary workpiece material codes. It fits into TPMT-compatible toolholders and is appropriate for both roughing and finishing passes depending on depth of cut. The maximum depth of cut is 4.00 mm (0.157 inches), making it well matched to medium-duty turning applications in job shops and production machining facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC907 grade solid carbide with TiAlN and TiN PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces and improves surface finish\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle (clearance code P) minimizes flank wear on difficult materials\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting for secure, repeatable insert positioning in the toolholder\u003c\/li\u003e\n\u003cli\u003eT chip breaker geometry promotes controlled chip evacuation during turning\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 standard for tool data representation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TPMT-compatible screw-held turning toolholders.

Use the appropriate torx or hex key as specified by the toolholder manufacturer to seat the clamping screw to the correct engagement without overtightening. Inspect the toolholder pocket and seating surface for chips or debris before installing a new insert. Follow the toolholder manufacturer documentation for proper torque procedure and insert orientation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC907\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: TiAlN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.50 mm (0.6496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1693 inches (4.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.00 mm (0.157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 5505522\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730501435698,"sku":"5505522","price":260.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a8f21b428d670e41433e2705d1e68c7.jpg?v=1788718566","url":"https:\/\/voomisupply.com\/products\/iscar-5505522-tpmt-321-ic907-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
