Manufactured to the TCMT21.51-MF2 industry standard, this insert features a CVD-applied Duratomic multilayer coating (TiCN, Al2O3, and Cr) that extends tool life across demanding cutting cycles. The insert carries a TP2501 manufacturer grade and is rated for use across material grades P10, P20, P30, and P35, making it well suited to general steel turning at a range of depths and feed rates. It provides 3 usable cutting edges per insert, a 1\/4 inch inscribed circle, and a 1\/64 inch corner radius with a chamfered and honed cutting edge style. Installation and setup are handled by machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily intended for steel workpieces, with secondary suitability for stainless steel and cast iron. The MF2 chip breaker geometry is optimized for finishing and medium finishing passes. Applicable operations include turning, facing, boring, and back turning, covering a broad range of lathe work in job shop and production environments. The screw-on insert holding method provides secure clamping in compatible TCMT-style toolholders. With a positive rake and neutral hand orientation, it fits a wide range of standard TCMT toolholder configurations used in both manual and CNC turning centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended wear resistance and heat management\u003c\/li\u003e\n  \u003cli\u003e3 cutting edges per insert with chamfered and honed edge preparation\u003c\/li\u003e\n  \u003cli\u003eMF2 chip breaker geometry suited to finishing and medium finishing passes\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with neutral hand orientation for versatile toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3937 inches for flexible operation across finish and semi-finish applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code TCMT110204-MF2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard stock insert for TCMT-style screw-clamp toolholders accepting a 1\/4 inch inscribed circle triangular insert.

Ensure the machine spindle is stopped and the turret is fully indexed and locked before changing inserts. Seat the insert fully against the toolholder pocket locating surfaces before tightening the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket and chip breaker seat for chips or damage before each index or replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TCMT-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TCMT21.51-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT110204-MF2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP2501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P10, P20, P30, P35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4331 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: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF2\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\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\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 Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 02956320\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557370822962,"sku":"02956320","price":195.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f63cbcb2727450579f84d2ce1197aae.jpg?v=1786386855","url":"https:\/\/voomisupply.com\/products\/seco-02956320-tcmt21-51-mf2-tp2501-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
