It features a CVD-applied TiCN and Al2O3 multilayer coating over a solid carbide substrate, giving it high wear resistance with adequate toughness for steel and stainless steel workpieces. The insert measures 15.9 mm (0.626 inches) in length with a 5\/8 inch (0.6248 inch) inscribed circle and a 3\/64 inch (0.0472 inch) corner radius. The 80-degree diamond (rhombic) shape and negative side clearance make it well suited for medium to heavy stock removal. Machinists and CNC operators install this insert as part of the ISCAR Isoturn toolholder system.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for roughing and medium machining passes on steel (ISO P) and stainless steel (ISO M) workpieces, with primary application in P-category materials and secondary application in M-category materials. The TF chip breaker geometry helps control chip flow during interrupted and continuous cuts at elevated feed rates. The maximum depth of cut is 6.00 mm (0.2362 inches), making it appropriate for moderate-to-aggressive turning passes in production and job-shop environments. It is held in the toolholder via clamp or pin-lock methods, both common configurations in standard CNMG-style turning blocks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated TiCN and Al2O3 multilayer finish for high wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eIC8250 grade delivers a balance of wear resistance and toughness across ISO P and M material groups\u003c\/li\u003e\n  \u003cli\u003eTF chip breaker geometry rated for roughing and medium machining applications\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with negative clearance (CNMG) for strong cutting edge\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 6.00 mm supports aggressive material removal rates\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin-lock toolholder holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 insert identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style toolholders within the ISCAR Isoturn system.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and screw type specified by the toolholder manufacturer when securing the clamp or pin-lock — do not overtighten by hand or with unrated tools. Inspect the toolholder seat and shim for damage before seating a new insert, as a damaged pocket will affect runout and insert life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG543\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG160612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8250\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3 (CVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6248 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.9 mm (0.626 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Negative Clearance)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P) - High Wear Resistance to High Toughness\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M) - High Wear Resistance to Moderate Wear Resistance and Toughness\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0025 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5550258\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737653313842,"sku":"5550258","price":408.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed53b2dc8453b1dfdf0487a31070fa4e.jpg?v=1788791903","url":"https:\/\/voomisupply.com\/products\/iscar-5550258-cnmg543tf-ic8250-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
