It carries the manufacturer grade 4415 with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability during interrupted and continuous cuts. The insert features an 80-degree diamond shape (Insert Shape Code C), a 0.79 mm corner radius (0.0313 inches), and a 12.70 mm inscribed circle (0.5 inches). The XM chipbreaker geometry is engineered for controlled chip formation across a range of cutting conditions. This insert belongs to the T-Max P series and is intended for use by machinists and CNC operators in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations on cast iron and similar materials (Primary Workpiece Material Code K) as well as steel (Secondary Workpiece Material Code P), covering both finishing and general-purpose turning passes. The neutral hand orientation makes it compatible with standard CNMG toolholders using clamp or screw holding methods. ISO designation is CNMG 12 04 08-XM 4415. Typical applications include external turning on medium to large workpieces in job shop or high-volume production settings where consistent tool life and predictable chip control are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for enhanced wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Code C) with neutral hand for versatile toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e0.79 mm corner radius (0.0313 inches) for balanced strength and surface finish capability\u003c\/li\u003e\n\u003cli\u003eXM chipbreaker geometry with G chip configuration for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eCNMG tolerance and clearance codes (M and N) for reliable seating and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method compatible with standard CNMG-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for applications requiring CNMG 432 (ISO: CNMG 12 04 08) inserts in grade 4415 within the T-Max P series.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamp or screw — do not overtighten, as this can fracture carbide. Inspect the insert seat and clamp for debris or damage before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 08-XM 4415\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-degree, Code C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\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\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.70 mm (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.1875 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\u003eChip Breaker\u003c\/strong\u003e: XM \/ G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\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: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7859297\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728305291570,"sku":"7859297","price":276.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a740b2aaa3e6566fd84ccf0bb823baa.jpg?v=1788690372","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859297-turning-insert-cnmg432-xm-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
