It carries the ANSI code CNGG431ESUJ and ISO code CNGG120404N-SUJ, featuring an 80-degree diamond insert shape with a negative rake geometry. The H1 manufacturer grade and ESUJ chip breaker make this insert well-suited for finishing and light cutting passes on non-ferrous workpiece materials. The uncoated carbide construction provides a sharp, consistent cutting edge without the thermal buildup associated with coated inserts. Licensed HVAC installers and machinists in precision turning applications will find this insert appropriate for tight-tolerance finishing work.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on non-ferrous metals, including aluminum and copper alloys, where a sharp uncoated edge is preferred to minimize built-up edge. It fits into CNGG-style toolholders using a clamp and pin holding method. The neutral hand orientation makes it suitable for both left- and right-hand turning setups. It is typically used in production or job-shop environments where CNC lathe operators require consistent chip control on softer, non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide, uncoated construction for sharp edge retention on non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Shape Code C) with negative rake for stable cutting geometry\u003c\/li\u003e\n\u003cli\u003eESUJ chip breaker designed for controlled chip formation during finishing cuts\u003c\/li\u003e\n\u003cli\u003eNeutral insert hand allows use in both left- and right-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method provides secure seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 standards for interchangeability and tool data exchange\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for CNGG-style turning toolholders that accept a 1\/2-inch inscribed circle, 3\/16-inch thick diamond insert with a clamp and pin holding method, per ANSI code CNGG431ESUJ.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert installation should be performed by a qualified machinist or CNC tooling technician with the machine powered off and the spindle locked. Seat the insert fully into the toolholder pocket before engaging the clamp and pin mechanism. Do not overtighten the clamping screw beyond the toolholder manufacturer's specified torque. Inspect the insert seat and pocket for chips or debris before installation to ensure proper seating and cutting edge alignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNGG431ESUJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNGG120404N-SUJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNGG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: H1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ESUJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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 Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1033W3M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51739065614642,"sku":"1033W3M","price":248.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05bdb98d46d290d2589116c95aa9f380.jpg?v=1788808785","url":"https:\/\/voomisupply.com\/products\/sumitomo-1033w3m-turning-insert-cngg431esuj-h1-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
