Manufactured under the CoroTurn 107 series, this insert carries the ISO designation TCMT 11 03 04-MM 1105 and features a TiAlN coating applied via PVD process for improved wear resistance and tool life at elevated cutting temperatures. The triangular 60-degree insert geometry provides three usable cutting edges, and the MM chip breaker geometry is optimized for controlled chip formation in steel and stainless steel applications. The insert measures 0.4071 inches in length with an inscribed circle of 0.25 inches and a corner radius of 0.0156 inches (1\/64 inch).\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for precision turning of steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material groups P, M, and S. The neutral hand orientation and screw-holding method make it suitable for standard TCMT-style toolholders used in production turning environments. Typical applications include finish and semi-finish turning passes where consistent surface finish and dimensional accuracy are required. Licensed machinists and CNC operators in job shops, production facilities, and maintenance machine shops are the primary installers of this insert type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN coating via PVD process for enhanced heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker geometry engineered for controlled chip evacuation in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eThree cutting edges per insert from 60-degree triangular geometry\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method with clearance code C and tolerance code M for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e0.0156 inch (1\/64 inch) corner radius suited for finish turning with tight corner requirements\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert compatible with standard TCMT-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TCMT-style screw-clamp toolholders compatible with the CoroTurn 107 series.

Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when seating the clamping screw — do not overtighten. Inspect the insert pocket and seating surface for debris or wear before installing a new insert. Dispose of worn carbide inserts in accordance with local regulations for metallic waste.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT 11 03 04-MM 1105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4071 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloy, Titanium (ISO P, M, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 5752518\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748824842546,"sku":"5752518","price":264.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2228d3b6e61744851f81f9f51cffed5_45beb95c-ef81-44fc-99f8-7dc010e5ad33.jpg?v=1788899081","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5752518-turning-insert-tcmt221-mm-1105","provider":"Voomi Supply","version":"1.0","type":"link"}
