It carries the ISCAR Isoturn series designation and features a multilayer PVD coating — TiAlN, AlTiN, and TiN — applied under the proprietary SumoTec process. The IC830 grade delivers a balance of wear resistance and toughness suited for interrupted and continuous cuts. The insert has a 0.75-inch (19.05 mm) inscribed circle, a 0.25-inch (6.35 mm) thickness, and a 0.047-inch (1.2 mm) corner radius. The GN chip breaker geometry targets roughing and medium machining operations. A licensed machinist or CNC operator installs and indexes this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel (ISO P), stainless steel (ISO M), special and super alloys (ISO S), and hardened materials (ISO H). The negative side clearance and square geometry support heavy stock removal as well as general-purpose turning. The right-hand cutting orientation and 90-degree included angle make it compatible with standard SNMG toolholders used in production turning environments, including job shops and aerospace component manufacturing. Maximum recommended depth of cut is 0.079 inch (2.0 mm).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC830 carbide grade with PVD-applied SumoTec TiAlN\/AlTiN\/TiN multilayer coating for extended tool life across multiple work materials\u003c\/li\u003e\n\u003cli\u003eGN chip breaker geometry optimized for roughing and medium machining applications\u003c\/li\u003e\n\u003cli\u003eSquare SNMG insert shape with negative side clearance — maximizes number of usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation; 90-degree included angle for rigid, stable engagement\u003c\/li\u003e\n\u003cli\u003e0.047-inch (1.2 mm) corner radius balances surface finish and edge strength in medium to heavy cuts\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for CAM and tool management system integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for SNMG643 (ISO: SNMG190612) toolholders with a 0.75-inch inscribed circle seat.

Use the correct torque wrench and clamping screws specified by the toolholder manufacturer — do not over-tighten the clamping mechanism. Inspect the insert pocket seat and clamping components for wear or debris before seating a new insert. Verify correct insert orientation and hand designation match the toolholder before resuming machining.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNMG643\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNMG190612\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN \/ AlTiN \/ TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD (SumoTec)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing \/ Medium Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.7500 inch (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.2500 inch (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0470 inch (1.2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.079 inch (2.0 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.7500 inch (19.06 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Special\/Super Alloys (S), Hardened Materials (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3308133\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730034458930,"sku":"3308133","price":428.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/798b4098c13f1ab8fc76f2efe9ed07a0.jpg?v=1788710532","url":"https:\/\/voomisupply.com\/products\/iscar-3308133-snmg643-carbide-turning-insert-ic830","provider":"Voomi Supply","version":"1.0","type":"link"}
