It carries an ISO code of CNMG 12 04 12-KRR 3210 and features a multilayer TiCN, Al2O3, and TiN coating over a solid carbide substrate. The KRR chip breaker geometry is optimized for cast iron machining, controlling chip flow and reducing cutting forces at moderate to heavy depths of cut. The insert measures 12.90 mm in length with a 0.5-inch inscribed circle and delivers 4 usable cutting edges per insert, maximizing cost-per-edge value in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily applied in turning operations where the primary workpiece material is cast iron, including gray, ductile, and compacted graphite iron grades. It is suited for medium to heavy roughing passes, with a maximum depth of cut of 11.70 mm. The neutral hand orientation and CNMG insert style make it compatible with standard CNMG-style toolholders used in turning centers, CNC lathes, and manual engine lathes across job shop and production machining environments. Installation is performed by machinists and CNC operators as part of routine insert indexing and toolholder maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer TiCN, Al2O3, and TiN coating for wear resistance and thermal protection in cast iron cutting\u003c\/li\u003e\n  \u003cli\u003eKRR chip breaker geometry engineered for controlled chip formation on cast iron workpieces\u003c\/li\u003e\n  \u003cli\u003e4 cutting edges per insert for extended tool life and reduced per-edge cost\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNMG) provides a strong cutting edge with versatile entry angles\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 11.70 mm supports medium to heavy roughing passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard CNMG toolholder configurations without left- or right-hand restrictions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style turning toolholders compatible with the SANDVIK COROMANT T-Max P system.

Seating surfaces on the toolholder pocket and clamping pin should be inspected and cleaned before installing a new insert. Do not exceed the maximum depth of cut specified for the insert geometry, and verify correct torque on the clamping screw per the toolholder manufacturer's documentation. Mixing insert grades or chip breaker styles within a multi-pass program may produce inconsistent surface finishes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 12-KRR 3210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: 80-Degree Diamond (C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KRR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches (12.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inches (0.0472 inches \/ 1.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4606 inches (11.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2032 inches (5.16 mm)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6042791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51735617962290,"sku":"6042791","price":297.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38014dd0a88de4ac5df765be33b95304_6faca329-4ba4-456e-8497-0b4312208a09.jpg?v=1788773293","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6042791-turning-insert-cnmg-3210","provider":"Voomi Supply","version":"1.0","type":"link"}
