It carries the ANSI designation RNMG43 and ISO designation RNMG120400. The insert features a multilayer CVD coating of TiC, TiCN, and TiN, placing it in the KC850 grade — engineered to balance wear resistance and toughness across a broad range of workpiece materials. With a 0.5 inch inscribed circle, a 0.25 inch corner radius, and a full 360-degree round profile, it is suited for medium machining chip-breaker conditions. Licensed machinists, CNC operators, and toolroom technicians install this insert into KENLOC-compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring operations on steel, stainless steel, and cast iron, with secondary suitability for special and super alloys. The round shape provides eight usable cutting edges per insert, making it a cost-efficient option for shops running moderate-to-high production volumes. The neutral hand designation means it performs in both left-hand and right-hand toolholder orientations. Typical applications include finish and semi-finish passes where a consistent corner radius and tight tolerances are required. The KC850 grade is particularly well-suited for interrupted cuts and conditions where edge toughness is as important as surface finish.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound insert shape (RNMG) delivers 8 cutting edges per insert, maximizing tool life value\u003c\/li\u003e\n  \u003cli\u003eKC850 multilayer CVD coating (TiC, TiCN, TiN) provides moderate wear resistance and high toughness across steel, stainless, and cast iron\u003c\/li\u003e\n  \u003cli\u003e0.5 inch inscribed circle with full radius geometry supports turning, facing, and boring in a single insert style\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.0492 inches (1.25 mm) for controlled semi-finish and finish passes\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance geometry for stable, chatter-resistant cutting action\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method compatible with KENLOC toolholder system\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge prep for consistent edge engagement and reduced microchipping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENLOC-series toolholders accepting RNMG43 round inserts.

Power down and lock out the machine spindle before seating or indexing the insert. Secure the insert using the appropriate KENLOC clamp and pin hardware torqued to the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or debris before each index to ensure correct seating and edge height repeatability.\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 Shape\u003c\/strong\u003e: R - Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (CVD Multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 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\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Common (Medium Machining)\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N (Negative)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K), Special and Super Alloys (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0154 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1160160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731854590258,"sku":"1160160","price":160.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c024954048d5d4f262212dc12a748b1a.jpg?v=1788735653","url":"https:\/\/voomisupply.com\/products\/kennametal-1160160-round-turning-insert-kc850-rnmg43","provider":"Voomi Supply","version":"1.0","type":"link"}
