It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal protection during continuous and interrupted turning operations. The insert has a neutral hand orientation and a 3\/4 inch inscribed circle with a 1\/16 inch corner radius. It is designed for use in ISO P material group applications and belongs to the CNMG-MR series, which incorporates the PR chip breaker geometry for controlled chip formation during steel turning.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external turning operations in ISO P workpiece material categories, primarily steel and steel castings. The CNMG shape and MR chip breaker geometry make it a practical choice for medium to finishing passes where chip control and surface finish consistency are priorities. The neutral hand designation allows seating in standard CNMG toolholders. It is typically used on CNC lathes and turning centers in production machining environments by machinists and manufacturing tradespeople working in job shop or production settings. The insert thickness is 1\/4 inch, and the insert style is compatible with clamp and screw holding methods.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCNMG insert shape with 0 degree relief angle and M tolerance, N clearance codes\u003c\/li\u003e\n  \u003cli\u003ePR chip breaker geometry for controlled chip evacuation on steel workpieces\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch inscribed circle and 1\/16 inch corner radius for medium to finishing applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and screw-style CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 4415 carbide substrate optimized for ISO P material group cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNMG toolholders that accept clamp and screw holding methods.

Power down and lock out the machine spindle before replacing any cutting insert. Inspect the insert pocket and seating surfaces for debris or damage prior to installation, as improper seating can cause insert fracture or poor surface finish. Cutting insert changes on CNC equipment should be performed by qualified machinists following applicable shop safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Designation\u003c\/strong\u003e: CNMG 19 06 16-MR 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\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\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eChip Breaker\u003c\/strong\u003e: PR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMG-MR (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches L x 2.13 inches W x 0.54 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.67 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: 8021125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51745962164530,"sku":"8021125","price":564.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ca2d523295033b7f6d267336371ad3e_b159da20-007e-49aa-a6a9-2c5e6041f507.jpg?v=1788866067","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-8021125-turning-insert-cnmg-19-06-16-mr-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
