Manufactured to ANSI code CNMG431CEAB30 and ISO code CNMG120404CE AB30, this insert features an 80-degree diamond shape with a negative rake angle and a 0-degree relief angle. It carries manufacturer grade AB30 with a CE chip breaker geometry. With an inscribed circle of 0.5 inches and a corner radius of 0.0156 inches (1\/64 inches), it is suited for finishing and semi-finishing operations where tight tolerances and consistent surface finish are required. Licensed machinists and CNC operators install this insert as part of routine tooling maintenance.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning applications on cast iron and hardened steel workpieces, corresponding to primary workpiece material codes K and H. The CE chip breaker geometry helps manage chip flow on difficult-to-machine ferrous materials. It is a neutral-hand insert, making it suitable for use in both right-hand and left-hand toolholders depending on the setup. Typical applications include OD turning, facing, and light profiling passes on production or job-shop turning equipment. The clamp-style insert holding method ensures secure seating in compatible CNMG-style toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic uncoated insert material for high-heat resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Shape Code C) with negative rake for increased cutting edge strength\u003c\/li\u003e\n\u003cli\u003eCE chip breaker geometry optimized for cast iron and hardened steel machining\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tooling value per unit\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard CNMG toolholder configurations\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method for rigid, repeatable insert positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for CNMG-style toolholders accepting a 0.5-inch inscribed circle, 3\/16-inch thick diamond inserts with clamp-style holding.

Use the appropriate torx or clamp screw driver to secure the insert clamp without overtightening. Inspect the toolholder pocket and clamp for wear or debris before seating the new insert. Verify insert orientation and hand designation match the programmed tool path before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG431CEAB30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120404CE AB30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AB30\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: Uncoated\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 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\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: CE\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: 0.508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 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\u003eWidth\u003c\/strong\u003e: 1.0 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: H, K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5700349\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972388356402,"sku":"5700349","price":25.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e79cc99344a1c1ec2420b1a8856e1c63.jpg?v=1789967366","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-5700349-turning-insert-cnmg431ce","provider":"Voomi Supply","version":"1.0","type":"link"}
