This insert carries a CVD-applied TiCN and TiN coating over a solid carbide substrate, designated manufacturer grade 235. The round insert shape provides a full 4 cutting edges, maximizing value per insert. At 0.1875 inches thick with a 0.5-inch inscribed circle, it suits a range of medium-duty turning applications. A screw-clamped holding method and standard M-tolerance geometry make it a direct fit for compatible CoroTurn 107 tooling systems. Installed by machinists and CNC operators in job shops and production environments.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for turning steel and stainless steel workpieces, covering ISO material groups P and M. The neutral hand orientation and round shape make it suitable for profiling, facing, and light to medium roughing passes. The CoroTurn 107 series is commonly used in positive-rake toolholder configurations on both manual and CNC turning equipment. The ISO designation for this insert is RCMT 12 04 00 235, and the chip breaker code is 00, indicating no chip breaker geometry. Typical applications include shaft turning, shoulder work, and contour turning on ferrous materials in both residential shop and industrial production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound RCMT insert shape with 4 usable cutting edges for extended tool life\u003c\/li\u003e\n\u003cli\u003eCVD-applied TiCN and TiN multilayer coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate, manufacturer grade 235\u003c\/li\u003e\n\u003cli\u003eScrew-clamped holding method for secure, repeatable seating in CoroTurn 107 toolholders\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation supports profiling and multi-direction turning passes\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle (clearance code C) reduces flank wear in continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroTurn 107 series toolholders that accept RCMT43 round inserts with a screw-clamp holding method.

Use the appropriate Torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw. Inspect the toolholder pocket and clamping screw for wear or damage before seating a new insert. Index or replace the insert when flank wear or chipping is observed to maintain dimensional accuracy and surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RCMT 12 04 00 235\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 235\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: TiCN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 00 (none)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.2 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5740569\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749532565810,"sku":"5740569","price":251.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43120a37298c4f4156a2d2b4ab22d158_3e81aab6-128d-41b8-bf6c-752bfa12fb4d.jpg?v=1788907297","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5740569-rcmt43-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
