It carries a multilayer CVD coating of TiCN, Al2O3, and TiN for elevated wear resistance and thermal stability. The 80-degree diamond shape (Insert Shape Code C) provides a strong cutting edge geometry with a 0-degree rake angle and a honed cutting edge, making it well suited to interrupted cuts and hard-to-machine ferrous materials. With 4 usable cutting edges per insert and compatibility with both clamp and pin holding methods, this insert delivers consistent tool life in demanding production environments. Licensed HVAC and trade professionals working with CNC machining will recognize the value of a well-engineered insert grade built for cast iron.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring operations on cast iron workpieces, corresponding to ISO material group K (K05 and K15). The CNMA543 profile  -  5\/8 inch inscribed circle, 1\/4 inch thickness, and 3\/64 inch corner radius  -  fits standard CNMA-style toolholders used in general-purpose and heavy-duty turning applications. The flat-top chip breaker and negative rake geometry are optimized for continuous and semi-interrupted cuts at moderate to high feed rates. A maximum depth of cut of 0.0787 inches supports finishing and semi-finishing passes. This insert conforms to ANSI and ISO standards for interchangeability across compatible toolholder systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating (TiCN, Al2O3, TiN) for extended wear life on cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 4 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003e3\/64 inch (0.0472 inch) corner radius with honed cutting edge style\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 0-degree clearance geometry for stable, chatter-resistant cuts\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards for dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for CNMA 543-style indexable toolholders accepting inserts with a 5\/8 inch inscribed circle, 1\/4 inch thickness, and clamp or pin retention.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamp hardware when seating the insert to avoid micro-fracturing the carbide substrate. Inspect the insert pocket and clamp for wear or debris before each insert change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMA 543\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T5105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 (Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6340 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0472 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N (0 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K05, K15\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNM\/GA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6850160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51973412159794,"sku":"6850160","price":360.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3001ab7e491dbbde93529af51f1f0fd_a9ca578a-ca27-465f-b1d8-9178bd75e0b3.jpg?v=1789973204","url":"https:\/\/voomisupply.com\/products\/tungaloy-6850160-cnma543-t5105-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
