Assigned ISO code DCMT070204KMH13A, this insert carries the H13A grade designation and features the KM chip breaker geometry optimized for controlled chip formation. With a 0.25-inch inscribed circle, a 0.0157-inch corner radius, and a maximum depth of cut of 0.2894 inches, it suits finishing and light semi-finish turning passes. The neutral hand orientation fits standard DCMT-style toolholders. Licensed machinists and CNC operators install this insert in precision turning cells across production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is part of the CoroTurn 107 series and is engineered primarily for cast iron workpieces, with secondary suitability for non-ferrous metals. It is appropriate for both light production and maintenance turning work where an uncoated carbide grade is preferred for edge sharpness and minimal built-up edge on non-ferrous alloys. The DCMT style and screw-clamping holding method make it compatible with a wide range of indexed toolholders accepting DCMT inserts in the 21.51 size class. Two cutting edges are available per insert, providing an economical cutting edge count for short to medium run jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eH13A uncoated solid carbide grade for sharp edge retention on cast iron and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eKM chip breaker geometry for controlled chip formation at finishing depths of cut\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DCMT) with neutral hand for versatile toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003e0.0157-inch corner radius for fine finishing surface finish results\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.2894 inches suitable for light to semi-finish turning passes\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping insert holding method for secure, repeatable seating in DCMT toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert for extended insert economy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DCMT-style screw-clamp toolholders accepting the 21.51 insert size class within the CoroTurn 107 series.

Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified procedure without overtorquing the insert pocket. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Always verify insert orientation and hand designation against the toolholder specification before resuming cutting operations.\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: DCMT070204KMH13A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-degree Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: H13A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3051 inches (7.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (2.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2894 inches (7.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\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\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\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: Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal (N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 21.51\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: 0.06 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: 5730726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737538429234,"sku":"5730726","price":158.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a33b78376aeb167d1cc3395314643c57_14d7d331-3e07-43bc-a5fd-76ed0fd5da5d.jpg?v=1788790024","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730726-turning-insert-dcmt21-51km-h13a","provider":"Voomi Supply","version":"1.0","type":"link"}
