It is a square-profile, single-sided indexable insert designed for high feed rate milling operations in metal-cutting applications. The insert features a PVD-applied TiAlN and TiN coating over a fine-grain carbide substrate, producing a hard, wear-resistant cutting edge suited to demanding machining conditions. Key dimensions include a 14.00 mm inscribed circle, a thickness of 5.56 mm, and a corner radius of 2.30 mm. With four cutting edges and a positive rake angle of 13 degrees, this insert is used by machinists and CNC tooling technicians in production milling environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in face milling, high feed milling, and ramping operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The M14 chip breaker geometry is optimized for moderate to heavy chip loads on these material groups. It is held in the cutter body by screw clamping and is compatible with the R217.21-SP14 and R220.21-SP14 cutter series. Applications range from roughing passes on carbon steel to finishing cuts on cast iron and titanium alloys in aerospace, automotive, and general machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with fine-grain substrate for edge toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlN and TiN dual coating for thermal stability and extended tool life\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 4 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eHigh feed rate cutting edge style for aggressive material removal rates\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry (13-degree rake angle) reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eM14 chip breaker geometry suited for steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible cutter body positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with R217.21-SP14 and R220.21-SP14 cutter series per manufacturer specifications.

Ensure the milling machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the correct torx or hex key for the clamping screw and follow the cutter body manufacturer torque specification — do not estimate. Inspect the insert pocket seating surface for chips or debris before seating a new insert, as contamination causes premature edge failure and poor surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPKT\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\u003eInscribed Circle\u003c\/strong\u003e: 14.00 mm (0.5512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5.56 mm (0.2189 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 2.30 mm (0.0906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 13 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\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\u003eCutting Edge Style\u003c\/strong\u003e: High Feed Rate, Single Sided\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.22 mm (0.2205 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R217.21-SP14, R220.21-SP14\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: SPKT140523TN-M14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SPKT140523TN-M14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: 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: 10068956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557827117362,"sku":"10068956","price":342.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b920b13916e3cff8c3d0c687d2d0f40.jpg?v=1786396190","url":"https:\/\/voomisupply.com\/products\/seco-10068956-milling-insert-spkt140523tn-m14-f40m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
