The insert features an 80-degree diamond shape, a neutral hand orientation, and a T-Land cutting edge style with a negative rake angle and 0-degree relief angle. It carries four usable cutting edges and is held via clamp, pin, or lever lock toolholders. The MR7 chip breaker geometry is engineered for medium roughing operations in cast iron, steel, and stainless steel applications. Dimensionally, the insert measures 0.6339 decimal inches in length with a 5\/8-inch inscribed circle and a 3\/64-inch corner radius.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for general-purpose CNC lathe and turning center operations including boring, facing, and external turning. Its primary workpiece material classification is cast iron (ISO K), with secondary suitability for steel (ISO P) and stainless steel (ISO M). The MR7 chip breaker geometry and Duratomic CVD coating make it a practical choice for medium-depth interrupted and continuous cuts in production machining environments. The 4-edge configuration provides cost-effective indexing in high-volume turning operations. Material grades K10, K20, and K30 define the applicable carbide classification range for this insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDuratomic CVD multilayer coating: TiCN, Al2O3, and Cr for wear resistance in ferrous machining\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (CNMG) insert shape with 4 indexable cutting edges\u003c\/li\u003e\n  \u003cli\u003eMR7 chip breaker geometry optimized for medium roughing in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eT-Land cutting edge style with negative rake and 0-degree clearance (N tolerance class M)\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut up to 0.5866 inches; 0.25-inch insert thickness and hole diameter\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; ISO code CNMG160612-MR7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders accepting clamp, pin, or lever lock insert retention.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before indexing or replacing the insert. Seat the insert firmly against the toolholder pocket walls and torque the clamping screw to the toolholder manufacturer's specification using the appropriate Torx or hex key. Inspect the insert pocket and shim for wear or damage before seating a new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMG-MR7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160612-MR7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG543-MR7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TK1501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K10, K20, K30\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\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MR7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.10 mm (0.6339 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0472 inches)\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 (ISO K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (ISO P), Stainless Steel (ISO M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\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\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 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: 03064016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559680147762,"sku":"03064016","price":49.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21db17dc6633fe6b90314c23cf31b2dc_32eae675-5bc8-46d5-a867-f5290eb3e6ea.jpg?v=1786437970","url":"https:\/\/voomisupply.com\/products\/seco-03064016-turning-insert-cnmg543-mr7-tk1501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
