The insert carries a DCMT21.50MF geometry designation: a 55-degree diamond shape with a neutral hand orientation and a 0.20 mm corner radius. It is coated with TiAlN2 via a PVD process, which supports higher cutting speeds and extended tool life when machining steel, stainless steel, superalloys, and titanium. The MF chip breaker geometry is suited for finishing and light cutting passes where controlled chip formation and surface finish are priorities.\u003c\/p\u003e\u003cp\u003eThis insert is intended for precision turning applications in production and job-shop environments. It is primarily recommended for steel workpieces and is also rated for stainless steel, superalloys, and titanium under ISO material codes P, M, and S. With a maximum depth of cut of 7.55 mm and a 6.35 mm inscribed circle, it fits toolholders designed around the DCMT 07 02 02 insert pocket specification. Machinists and CNC operators performing finish-turning passes on ferrous and high-temperature alloys are the primary users of this insert grade and geometry combination.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN2 PVD coating supports elevated cutting temperatures and extended edge life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eMF chip breaker geometry optimized for finishing cuts and controlled chip formation\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with 0.20 mm corner radius for profiling and contour turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard DCMT-style toolholders without directional restriction\u003c\/li\u003e\n\u003cli\u003eScrew-holding method provides secure clamping with repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for cost-effective use in high-volume turning operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting the DCMT 07 02 02 insert pocket per ISO standards, consistent with the CoroTurn 107 toolholder series.

Use the correct torque-limiting screwdriver for the insert clamping screw to avoid seat damage; consult the toolholder manufacturer documentation for torque guidance. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Follow applicable shop safety procedures and machine guarding requirements when changing inserts on live tooling systems.\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\u003eISO Code\u003c\/strong\u003e: DCMT 07 02 02-MF 1105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1105\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: TiAlN2\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-Degree Diamond\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\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 6.35 mm (0.250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 7.75 mm (0.3051 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 2.38 mm (0.0938 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 7.55 mm (0.2972 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 2.80 mm (0.1102 inches)\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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: Steel, Stainless Steel, Superalloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5730731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727543828786,"sku":"5730731","price":266.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d29f9ef2e00929dcadc3c2a47352fa85.jpg?v=1788679103","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5730731-turning-insert-dcmt21-50mf-1105","provider":"Voomi Supply","version":"1.0","type":"link"}
