It features a PVD-applied multilayer TiAlN and TiN coating over a solid carbide substrate, giving it strong wear resistance and thermal stability. The F1 chip breaker geometry produces a sharp cutting edge with a positive rake angle, making it well suited for finishing and semi-finishing passes. The insert measures 0.25 inches inscribed circle with a 0.0157-inch corner radius and a 0.09-inch thickness. It is held in the toolholder by a screw-clamp method and delivers three usable cutting edges per insert. Licensed machinists and CNC operators install this insert as a consumable tooling component in production turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated primarily for stainless steel (ISO material code M) and is also compatible with steel, cast iron, and super-alloys including titanium (ISO codes P, K, and S). Material grades M10, M20, and M30 are covered. The multi-use application scope includes turning, facing, boring, and back turning, making it a versatile choice for shops running mixed-material jobs on a single setup. The insert conforms to both ANSI and ISO standards and carries the ISO designation TCMT110204-F1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCP500 grade solid carbide with PVD multilayer TiAlN and TiN coating for extended tool life on stainless steel\u003c\/li\u003e\n  \u003cli\u003eF1 chip breaker geometry with positive rake angle and sharp cutting edge for reduced cutting forces on finishing cuts\u003c\/li\u003e\n  \u003cli\u003eThree cutting edges per insert (neutral hand) maximizing cost-per-edge efficiency\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.39 inches supports both light finishing and moderate semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method provides rigid seating and repeatable edge positioning\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code TCMT110204-F1 for cross-reference with other suppliers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TCMT-style screw-clamp turning toolholders conforming to ANSI and ISO TCMT insert pocket specifications.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to secure the clamp screw — over-tightening can crack the carbide substrate. Inspect the insert pocket for chips or debris before seating a new edge, and verify edge orientation against the toolholder print before resuming cuts.\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\u003eIndustry Standard Number\u003c\/strong\u003e: TCMT21.51-F1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TCMT110204-F1\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 and TiN (PVD Multilayer)\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\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: 0.4331 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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: F1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel (P), Cast Iron (K), Super-alloys and Titanium (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M10, M20, M30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Back Turning, Boring, Facing, 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: 0.2 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02430421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560280391986,"sku":"02430421","price":192.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1555e62c76ba39b2ae646fb686cec035.jpg?v=1786450067","url":"https:\/\/voomisupply.com\/products\/seco-02430421-turning-insert-tcmt21-51-f1-cp500-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
