It carries a TiAlN and AlCr2O3 dual-layer coating applied via PVD process, delivering heat resistance and edge wear protection during continuous and light interrupted cuts. The insert features a 55-degree diamond shape, a 1\/4-inch inscribed circle, and a 1\/64-inch corner radius, making it well suited for finishing and semi-finishing passes where tight tolerances and surface finish matter. It belongs to the CoroTurn 107 series and is held in place by a screw-clamp system.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for machining steel as the primary workpiece material, with secondary suitability for stainless steel, non-ferrous metals, superalloys, and titanium. The UM chip breaker geometry is optimized for light to medium depth-of-cut applications in these material groups. Typical installations include external longitudinal turning, facing, and profiling operations on CNC turning centers in production and job-shop environments. The neutral hand orientation allows use in standard right-hand toolholders designed for DCMT insert pockets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN and AlCr2O3 PVD coating for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape provides a sharp, low-cutting-force geometry suited for profiling\u003c\/li\u003e\n  \u003cli\u003eUM chip breaker geometry optimized for light to medium finishing cuts in steel and multi-material applications\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius supports tight-tolerance finishing and reduced surface roughness\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method provides secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert, neutral hand orientation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders and any screw-clamp DCMT-style insert pocket accepting a 1\/4-inch inscribed circle insert with a clearance code C and tolerance code M.

Power down the spindle and engage all machine locks before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw and avoid over-tightening, which can crack the carbide. Verify the insert seats fully and flush in the pocket before resuming cuts, and confirm correct ISO toolholder designation matches the DCMT insert style.\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\u003eISO Code\u003c\/strong\u003e: DCMT 07 02 04-UM 1125\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN \/ AlCr2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55 Diamond (Shape Code D)\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: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches \/ 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.2894 inches (7.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0938 inches \/ 2.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Non-Ferrous Metal, Superalloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 5730998\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51740174188850,"sku":"5730998","price":215.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49a341a51192e9f50193c690b0d90852_46a89685-8252-4650-a5b4-4988c10cd26a.jpg?v=1788823175","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730998-turning-insert-dcmt21-51-um-1125","provider":"Voomi Supply","version":"1.0","type":"link"}
