It features a square shape with a 90-degree included angle, four usable cutting edges, and a neutral hand orientation. The CVD-applied Duratomic coating combines TiCN and Al2O3 layers to deliver wear resistance and thermal stability during milling operations. With a 0.1874-inch thickness, a 0.5-inch inscribed circle, and a T-Land cutting edge style with a 4-degree rake angle and 20-degree relief angle, this insert is engineered for productive material removal. It is installed by machinists and toolroom technicians working with CNC or manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended primarily for milling cast iron (ISO material code K) in production and job-shop environments. The micrograin carbide substrate and Duratomic multilayer coating suit interrupted cuts and abrasive cast iron grades where edge stability is critical. The M15 chip breaker geometry is optimized for light-to-medium depths of cut up to 0.3425 inches. The screw-holding method provides positive clamping in compatible toolholders. Both high-volume production cells and lower-volume precision shops regularly use this insert family for face milling and shoulder milling cast iron components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSquare SEMX insert style with 90-degree included angle and four cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eCVD Duratomic coating: TiCN plus Al2O3 multilayer for wear and heat resistance in cast iron\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for edge integrity under abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003eM15 chip breaker geometry with positive rake and T-Land edge for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3425 inches with a 0.5-inch effective cutting edge length\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation allows use in both climb and conventional milling setups\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.

Fully de-energize and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder specification — do not overtighten, as this can fracture the carbide body. Inspect the insert pocket and seating surfaces for chips or debris before fitting a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: SEMX1204AFTN-M15\u003c\/li\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: MK1500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiCN and Al2O3 (CVD Duratomic)\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\u003eChip Breaker\u003c\/strong\u003e: M15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1204\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\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\u003eHole Diameter\u003c\/strong\u003e: 0.1772 inches\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: Cast Iron (ISO code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R217.53-12 and R220.53-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (minimum order quantity: 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: 02566282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559112180018,"sku":"02566282","price":304.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c17b9774e93682b82081bb4015a07a9b.jpg?v=1786427958","url":"https:\/\/voomisupply.com\/products\/seco-02566282-milling-insert-semx1204aftn-m15-mk1500","provider":"Voomi Supply","version":"1.0","type":"link"}
