Part of the CoroTurn 107 series, this insert features a 55-degree diamond shape with a 7-degree relief angle and a neutral hand orientation. The dual-layer TiAlN and AlCr2O3 coating is applied via PVD process, delivering strong heat and wear resistance at the cutting edge. The 0.20 mm corner radius and MF chip breaker geometry make this insert well suited for light to medium finishing cuts on challenging workpiece materials. Licensed HVAC techs and machinists operating CNC lathes will recognize this as a high-precision indexable insert for controlled, repeatable material removal.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for machining stainless steel (ISO material code M) and is also rated for superalloys and titanium (ISO material code S). The DCMT geometry and MF chip breaker work together to produce controlled chip formation and reduced cutting forces on heat-resistant and work-hardening materials. It is a direct fit for CoroTurn 107 toolholders that accept screw-lock DCMT inserts with a 3\/8-inch inscribed circle. Typical applications include external turning, light facing, and contour work on CNC lathes in production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e55-degree diamond insert shape (shape code D) for versatile external turning and contouring\u003c\/li\u003e\n  \u003cli\u003eTiAlN and AlCr2O3 dual-layer PVD coating for wear resistance on stainless steel and superalloys\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry optimized for light to medium finishing cuts with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003e7-degree relief angle (clearance code C) reduces friction and supports free-cutting action\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method (hole diameter 0.1732 inches) for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for cost-effective tool life management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroTurn 107 toolholders accepting DCMT screw-lock inserts with a 3\/8-inch (0.3750 inch) inscribed circle.

Use the appropriate Torx or hex key as specified by the CoroTurn 107 toolholder documentation to seat the clamping screw — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Confirm the insert is fully seated and the clamping screw is secure before resuming any cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55-degree included angle)\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: 1115\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 AlCr2O3\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: MF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4499 inches (11.43 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and Titanium (ISO code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT 11 T3 02-MF 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 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: 5730691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732604191026,"sku":"5730691","price":275.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/717cca8dc22be06c3d4c61c98bb15af5_c4c0ada6-5147-4d3d-8840-c694c9e0a541.jpg?v=1788744887","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730691-turning-insert-dcmt-3-8-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
