Built from carbide with a CVD coating applied via chemical vapor deposition, this insert delivers wear resistance and thermal stability during continuous and interrupted cuts. The rhombic 80-degree insert geometry provides a strong cutting edge suited for medium to heavy material removal. With a corner radius of 0.0472 inches (1.20 mm) and a negative rake angle, it is optimized for rigid setups where tool pressure and edge integrity are priorities. Installation is handled by machinists and CNC operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily intended for turning cast iron workpieces, reflecting its K-grade classification for ferrous, non-steel materials. The MC5125 manufacturer grade and RK chip breaker geometry make it a practical choice for roughing and semi-finishing passes on gray iron, ductile iron, and similar cast materials. The neutral hand orientation allows use in both conventional and back-turning applications. Each insert provides four usable cutting edges, supporting cost-effective tool management in high-volume turning operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG insert style with 80-degree rhombic shape for strong, stable cutting geometry\u003c\/li\u003e\n  \u003cli\u003eCVD carbide coating in MC5125 grade for wear resistance on cast iron\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tool life and reduced cost per edge\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0472 inches (1.20 mm) suitable for medium surface finish requirements\u003c\/li\u003e\n  \u003cli\u003eRK chip breaker designed to manage chip control during cast iron turning\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard and back-turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard CNMG indexable insert toolholders accepting a 5\/8-inch inscribed circle, 1\/4-inch thick CNMG inserts with negative side clearance and M-tolerance classification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCNMG turning inserts are seated and secured by a qualified machinist or CNC operator following the toolholder manufacturer's clamping procedure. Power down and lock out the machine spindle before indexing or replacing inserts. Use appropriate insert seating tools to ensure the insert is fully seated against the pocket locating surfaces before applying clamping torque. Handle carbide inserts with care to avoid chipping cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG\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: Rhombic 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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: MC5125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (1.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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: RK\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\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.51 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: MITSUBISHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22905581\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51720481571122,"sku":"22905581","price":397.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/defeb1cec9b7d74050261062ed9788a7.jpg?v=1788564738","url":"https:\/\/voomisupply.com\/products\/mitsubishi-22905581-cnmg-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
