This square-geometry insert features a fine-grain carbide substrate with a PVD-applied TiAlN and TiN dual coating for wear resistance across demanding cutting applications. With four usable cutting edges, a positive rake angle of 4 degrees, a T-Land cutting edge style, and a 90-degree included angle, this insert is engineered for efficient chip formation and consistent tool life. It is single-sided and mounted by screw into compatible cutter bodies. Licensed machinists and CNC tooling specialists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The M15 chip breaker geometry supports medium cutting conditions where controlled chip flow is critical. Compatible cutter series include R217.53-12 and R220.53-12 as stated by the manufacturer. The insert follows ISO standards and carries the ANSI and ISO code SEMX1204AFTN-M15, making cross-referencing straightforward for tooling engineers and procurement teams. Typical applications span both roughing and semi-finishing passes in production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain substrate with PVD TiAlN and TiN dual coating for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum value per piece\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle with T-Land edge prep supports efficient chip formation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eM15 chip breaker geometry optimized for medium-condition milling on a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle and neutral hand orientation for versatile cutter body compatibility\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method for secure, repeatable positioning in the cutter pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with SECO cutter series R217.53-12 and R220.53-12 as specified by the manufacturer.

Ensure the machine spindle is fully stopped and locked out before accessing the cutter body. Use the manufacturer-specified torx or hex key to seat the clamping screw to the cutter body torque specification — do not over-torque, as this can fracture the carbide insert. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure proper seating and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEMX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: F40M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide, Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 4 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0441 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1772 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3425 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SEMX-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R217.53-12, R220.53-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SEMX1204AFTN-M15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEMX1204AFTN-M15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 02426750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561449718066,"sku":"02426750","price":290.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/907bf5ecb2e16cd34a925f73b58bcfce.jpg?v=1786464607","url":"https:\/\/voomisupply.com\/products\/seco-02426750-milling-insert-semx1204aftn-m15-f40m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
