It carries an 80-degree diamond shape (insert shape code C), a neutral hand orientation, and a 0 degree relief angle (clearance code N). The inscribed circle measures 0.5 inches, insert thickness is 0.1875 inches, and the corner radius is 0.0313 inches. These dimensional characteristics make it well suited to negative-rake toolholders conforming to CNMG standards. Licensed machinists and CNC operators use this insert for precision turning operations where surface integrity and tool life are the primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed primarily for turning stainless steel (ISO workpiece material code M), a category that demands a tough, wear-resistant carbide grade. Typical applications include OD turning, facing, and profiling of austenitic and martensitic stainless alloys on CNC lathes in job-shop and production environments. The EEM chip breaker geometry is suited for moderate depth-of-cut passes where chip control on difficult-to-machine materials is critical. The AC6030M grade pairs CVD coating technology with a carbide substrate engineered for the heat and built-up-edge challenges common in stainless machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC6030M grade with CVD coating for wear resistance in stainless steel turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNMG) provides two usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eEEM chip breaker geometry aids chip control at moderate feed and depth-of-cut ranges\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert fits standard CNMG-style negative-rake toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI code CNMG432EEM and ISO code CNMG120408N-EM for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method for secure seating under interrupted or continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style negative-rake turning toolholders that accept a 0.5-inch inscribed circle insert with a clamp-and-pin holding method.

Seat the insert fully against the pocket locating surfaces and verify the clamp and pin are engaged before resuming operation. Inspect the insert pocket for wear or debris that could affect seating and runout. Follow the toolholder manufacturer torque and clamping specifications for the specific clamp screw used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG432EEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408N-EM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC6030M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: CVD Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (Code M)\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 (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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: 0.5079 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: 0.0313 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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\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\u003eWeight\u003c\/strong\u003e: 0.1 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 196CCNB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51752969077042,"sku":"196CCNB","price":192.64,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/sumitomo-196ccnb-turning-insert-cnmg432eem-ac6030m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
