This insert carries the DCMT 21.51MF2 geometry with a CP500 manufacturer grade and a multilayer PVD-applied TiAlN plus TiN coating. The 55-degree diamond (rhombic) shape provides a sharp, positive rake cutting edge with a 7-degree relief angle. With a 0.0157-inch corner radius and a maximum depth of cut of 0.2913 inches, this insert is engineered for light, accurate finishing cuts where tight tolerances and surface finish are the priority. It is held in the toolholder via a through-hole screw clamp method and delivers two usable cutting edges per insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes on stainless steel, steel, cast iron, superalloys, and titanium. The MF2 chip breaker geometry is optimized for finishing applications, producing controlled chip flow at lower feeds and depths of cut typical in precision turning work. Applicable operations include turning, facing, boring, and back turning. The CP500 grade with PVD coating provides moderate-to-high wear resistance paired with sufficient toughness for interrupted or variable-surface cuts across P, K, and S workpiece material classifications. Machinists and CNC operators in production and job shop environments will find this insert appropriate for tight-tolerance final passes on a range of ferrous and high-temperature alloy materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDCMT 21.51MF2 geometry with 55-degree diamond insert shape and positive rake for clean finishing cuts\u003c\/li\u003e\n  \u003cli\u003eCP500 grade with multilayer PVD TiAlN plus TiN coating for wear resistance on steel, cast iron, and superalloys\u003c\/li\u003e\n  \u003cli\u003eMF2 chip breaker designed specifically for finishing operations with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert, screw-clamp holding method, neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003e0.0157-inch corner radius and 0.2913-inch maximum depth of cut support precision, light-pass machining\u003c\/li\u003e\n  \u003cli\u003eConforms to both ANSI (DCMT21.51) and ISO (DCMT070204) standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ANSI- and ISO-compliant DCMT-style indexable insert for screw-clamp turning toolholders accepting a 55-degree diamond insert with a 0.1142-inch hole diameter.

Ensure the machine spindle is stopped and the turret is in a safe, indexed position before changing inserts. Seat the insert firmly against the toolholder pocket locating surfaces before torquing the clamp screw; an improperly seated insert will affect dimensional accuracy and can cause premature edge failure. Do not exceed the insert's rated maximum depth of cut, and verify that the toolholder grade and overhang are appropriate for the intended operation before running the first pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT21.51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT070204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DCMT-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CP500\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 plus TiN, PVD process, multilayer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 55-degree Diamond (Rhombic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF2 (Finishing)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2913 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\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: Stainless Steel (P, K, S classification)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Operations\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02755038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563066523954,"sku":"02755038","price":208.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dff272336ec72f46dc1765ef6a70e201.jpg?v=1786489592","url":"https:\/\/voomisupply.com\/products\/seco-02755038-dcmt-21-51mf2-cp500-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
