This insert carries the TK0501 manufacturer grade and features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, delivering wear resistance and thermal stability at the cutting edge. The 80-degree diamond shape (CNMA543) provides a strong included angle suited to demanding cuts. With a neutral hand orientation and a chamfered and honed cutting edge, it handles boring, facing, and turning operations with consistent edge integrity. Licensed machinists and CNC operators working with cast iron and hard materials will find this insert well matched to production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for cast iron (ISO material group K) and hard materials (group H), covering ISO grade designations K05, K10, and K15. The flat-top chip breaker and zero rake angle are optimized for negative-rake toolholders in applications where edge stability and surface finish consistency are priorities. Typical use cases include production turning on hardened components, roughing and semi-finishing passes on cast iron housings, and multi-operation setups involving boring, facing, and OD turning on the same setup.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for extended tool life on abrasive workpieces\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with chamfered and honed cutting edge for strength and finish quality\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert maximize value per unit in production environments\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock insert-holding methods for broad toolholder flexibility\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry supports negative-rake toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eCompliant with both ANSI and ISO standards (ISO code CNMA160612)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in negative-rake CNMA-style toolholders accepting a 5\/8-inch inscribed circle insert.

Power down and lock out the machine spindle before indexing or replacing inserts. Ensure the insert pocket and seating surfaces are clean and free of chips before seating this insert, as debris under the insert will cause premature edge failure or dimensional error. Follow toolholder manufacturer torque guidance for the clamping screw; do not overtighten.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMA543\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMA160612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-degree Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TK0501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K05, K10, K15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (Duratomic CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\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: Negative (Rake Angle 0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6339 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (3\/64 inch, 1.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5866 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: 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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 03062545\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564167823666,"sku":"03062545","price":50.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/251d2afd254d431047b17980c9bc552f_a63ba921-d823-4041-af74-6b49739bee69.jpg?v=1786513049","url":"https:\/\/voomisupply.com\/products\/seco-03062545-carbide-turning-insert-cnma543-tk0501","provider":"Voomi Supply","version":"1.0","type":"link"}
