Manufactured to ISO 13399 standards, this insert carries the IC830 grade designation with a multi-layer PVD coating stack of TiAlN, AlTiN, and TiN, marketed under ISCAR's SumoTec proprietary coating process. The GN chip breaker geometry is engineered for controlled chip formation during medium to finish turning passes. At 15.5 mm in length with a 12.7 mm inscribed circle and a 1.2 mm corner radius, this insert delivers consistent edge geometry suited to tight-tolerance turning work. It is intended for right-hand cutting configurations and carries a positive rake orientation.\u003c\/p\u003e\u003cp\u003eThis insert belongs to ISCAR's Isoturn series and is rated for primary workpiece material groups M (stainless steel), P (carbon and alloy steel), and S (heat-resistant superalloys and titanium). It is well suited for medium turning and finishing passes where controlled chip evacuation and edge stability are required. The DNMG form factor (55-degree diamond, N clearance, M tolerance) fits standard DNMG toolholders commonly used in production turning environments. Maximum depth of cut is 5.0 mm. This insert is typically deployed in job shops, production machining cells, and aerospace or energy component manufacturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC830 grade with SumoTec PVD coating: TiAlN, AlTiN, and TiN layers for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eGN chip breaker for positive rake, controlled chip flow in medium to finish turning\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (DNMG) with N clearance and M tolerance per ISO standard\u003c\/li\u003e\n\u003cli\u003e1.2 mm corner radius (0.047 inches) suitable for moderate finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 5.0 mm (0.197 inches)\u003c\/li\u003e\n\u003cli\u003eRated for workpiece material groups M, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for DNMG 433 toolholders conforming to ISO 13399 standards.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when seating the insert clamp — do not over-tighten the clamping screw. Inspect the insert pocket and shim for damage or debris before seating a new insert, as a contaminated pocket will compromise edge repeatability and can cause premature failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 433-GN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN, AlTiN, TiN (SumoTec PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 15.5 mm (0.610 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.7 mm (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.187 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.2 mm (0.047 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 5.0 mm (0.197 inches)\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: M (stainless steel), P (steel), S (superalloys)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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: 3308180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755620172082,"sku":"3308180","price":298.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6400e942f10eee558faf71dfcb35bfb4.jpg?v=1788957065","url":"https:\/\/voomisupply.com\/products\/iscar-3308180-dnmg433-gn-ic830-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
