It features a 55-degree diamond insert shape with a neutral hand orientation, making it suited for profiling and finishing cuts. The insert is manufactured from solid carbide with a PVD-applied TiCN and TiN coating under the 1525 grade, which provides wear resistance and thermal stability. The UM chip breaker geometry controls chip flow across a range of feed rates and depths of cut. Licensed machinists and CNC operators in production machining environments are the primary installers and users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is part of the CoroTurn 107 series and is intended for turning steel as its primary workpiece material, with stainless steel and cast iron as secondary workpiece materials. It is suited for both light finishing and moderate roughing passes in these material categories. The screw-on holding method and DCMT geometry are compatible with toolholders designed to the DCMT insert style and clearance code C with tolerance code M. This insert is commonly used in job shops and production facilities running steel and stainless components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e55-degree diamond insert shape (Insert Shape Code: D) for profiling and finish turning\u003c\/li\u003e\n\u003cli\u003ePVD-coated TiCN and TiN layers under grade 1525 for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003eUM chip breaker geometry for effective chip control on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible toolholder pairing\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for extended service life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for CoroTurn 107 series DCMT-style toolholders.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as this can fracture the insert. Verify correct insert orientation and seating before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eGrade\u003c\/strong\u003e: 1525\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: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UM\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 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.442 inches (11.23 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT 11 T3 04-UM 1525\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 5730987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731795345714,"sku":"5730987","price":281.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3502416c38379be0c53c1e01174e8dfc.jpg?v=1788735026","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730987-turning-insert-55-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
