It carries the industry standard designation RNG43T0820 and is manufactured in the KY3500 grade, a silicon nitride ceramic formulation that delivers high wear resistance with moderate toughness. The insert features a flat top chip breaker geometry, a T-land cutting edge style, and a negative rake angle with neutral hand orientation. With 8 available cutting edges per insert, it offers efficient tool life management in production turning environments. Licensed machinists and CNC operators working in job shop or production settings are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on cast iron components in both roughing and finishing applications where wear resistance is the priority. The RNG43T0820 designation corresponds to ANSI size code 43 and ISO size code 120400. It fits toolholders designed for round RNG-style inserts with a 0.5 inch inscribed circle. The flat top geometry and negative side clearance make it well-matched for rigid, high-speed cast iron passes where insert security and edge integrity are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicon nitride ceramic grade KY3500 — optimized for high wear-resistance to moderate wear-resistance and toughness on cast iron (K-grade material)\u003c\/li\u003e\n\u003cli\u003eRound insert shape (R) with full radius geometry and 0.5 inch inscribed circle\u003c\/li\u003e\n\u003cli\u003e8 cutting edges per insert with neutral hand orientation for flexible toolholder use\u003c\/li\u003e\n\u003cli\u003eFlat top chip breaker and T-land cutting edge style for controlled engagement on cast iron\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance for secure clamping and edge stability at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish — no coating variability, consistent ceramic substrate performance\u003c\/li\u003e\n\u003cli\u003eMulti-use capable: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in RNG-style round insert toolholders with a 0.5 inch inscribed circle, accepting ANSI size code 43 (ISO 120400) inserts with a clamp-type insert holding method.

Ensure the toolholder pocket is clean and free of chips or debris before seating the insert. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not overtighten the clamp screw. Inspect the cutting edge and seating surface before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: RNG43T0820\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RNG43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RNG120400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KY3500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Silicon Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: R - Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 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\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\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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\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 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\u003eSide Clearance\u003c\/strong\u003e: Negative\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: G\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (K)\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\u003eSeries\u003c\/strong\u003e: KENDEX\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: 0.0084 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 1183574\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734674932018,"sku":"1183574","price":167.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/907a8cb7ae0e2e17e333410dbf903f08.jpg?v=1788764737","url":"https:\/\/voomisupply.com\/products\/kennametal-1183574-ceramic-turning-insert-rng43t0820","provider":"Voomi Supply","version":"1.0","type":"link"}
