It carries the ISO designation RCMT 12 04 M0-SM 1125 and features a dual-layer PVD coating of TiAlN and AlCr2O3 for extended tool life in demanding cutting conditions. The insert has a 12 mm inscribed circle, a thickness of 0.1875 inches (3\/16 inches), and four usable cutting edges. It is intended for use by machinists and CNC turning specialists working with difficult-to-machine materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for stainless steel (ISO material code M) and is rated as a secondary choice for superalloys and titanium (ISO material code S). The SM chip breaker geometry is suited for light to medium finishing passes where chip control and surface finish are critical. The screw-holding method and C clearance code make it compatible with standard CoroTurn 107 toolholders. It is a neutral-hand insert, usable in both right- and left-hand setups depending on holder orientation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound insert shape (RCMT) with 4 cutting edges for maximum economy per insert\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlN and AlCr2O3 dual-layer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSM chip breaker geometry optimized for finishing on stainless steel\u003c\/li\u003e\n  \u003cli\u003e12 mm inscribed circle with 4.40 mm hole diameter for screw-on mounting\u003c\/li\u003e\n  \u003cli\u003e7-degree relief angle (clearance code C) reduces cutting forces on thin-wall workpieces\u003c\/li\u003e\n  \u003cli\u003eGrade 1125 carbide substrate rated for stainless steel, superalloy, and titanium applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT CoroTurn 107 series toolholders that accept RCMT 12 04 style inserts with screw clamping.

Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key specified for the CoroTurn 107 holder to seat and torque the clamping screw — do not overtighten, as this can chip the insert seat. Inspect the insert pocket and seating surface for debris or wear before indexing to a fresh cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: RCMT 12 04 M0-SM 1125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round (R)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCr2O3\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: 12 mm (0.4724 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 4.76 mm (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.40 mm (0.1732 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: SM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and Titanium (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5740623\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730675925298,"sku":"5740623","price":275.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aaf7222e100ad1430a156f2c949e0f11.jpg?v=1788721318","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5740623-rcmt-12-04-m0-sm-1125-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
