It carries a 0.5-inch inscribed circle, a 0.25-inch corner radius, and a thickness of 0.1875 inches. The insert delivers 8 usable cutting edges through a neutral hand orientation and negative rake geometry (-15 degrees). Cutting edges are chamfered and honed for controlled entry. Designed for turning, facing, and boring operations, this insert is installed by machinists and CNC operators working in production and job-shop environments where insert consistency and tool life are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for roughing and medium machining operations. Its AH120 grade provides a balance of wear resistance and toughness, making it applicable across steel, stainless steel, cast iron, and superalloys including titanium. Material grades P15, P25, M15, M25, K15, K30, S10, and S25 are covered. The maximum depth of cut is 0.0787 inches. The insert is retained by clamp or pin holding methods and is compatible with toolholders designed for negative-rake RNMG geometry. It conforms to both ANSI and ISO standards, with ANSI size code 43 and ISO code RNMG120400.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound insert shape (full radius) with 8 cutting edges for extended tool life per insert\u003c\/li\u003e\n  \u003cli\u003eAH120 grade PVD TiAlN coating  -  moderate to high wear resistance with toughness for interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eNegative rake angle of -15 degrees with chamfered and honed cutting edge prep\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n  \u003cli\u003eCovers P, M, K, and S workpiece material classifications per ISO coding\u003c\/li\u003e\n  \u003cli\u003eChip breaker code 61 optimized for roughing through medium machining stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for RNMG43-61 AH120 grade toolholders accepting negative-rake round inserts with ANSI size code 43 and ISO code RNMG120400.

The machine spindle must be stopped and the toolholder fully secured in the turret before seating or indexing the insert. Use the appropriate torx or hex key specified by the toolholder manufacturer to achieve proper clamping force  -  do not overtighten or use impact tools on the clamping screw. Inspect the insert seat and chip pocket for debris before each index to ensure full seating and accurate cutting geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RNMG43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RNMG120400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: R - Round (Full Radius)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 61 (Roughing \/ Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp \/ Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grades\u003c\/strong\u003e: P15, P25, M15, M25, K15, K30, S10, S25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 6805899\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51995023311154,"sku":"6805899","price":195.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dce6fce8dda9583e3c78cc57d28442f.jpg?v=1789992397","url":"https:\/\/voomisupply.com\/products\/tungaloy-6805899-turning-insert-rnmg43-61-ah120-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
