Finished with an Al2O3 coating applied via CVD process, the insert is designed for precision turning operations in CNC and manual lathe applications. It carries a neutral hand orientation and a 90-degree square shape, making it suitable for straight profiling and facing passes. The AC830P manufacturer grade indicates a coated carbide formulation engineered for thermal resistance and wear performance across steel and universal workpiece materials. Licensed machinists and CNC operators working in production or job-shop environments are the primary installers and users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for use with secondary workpiece material codes M and P, covering a broad range of steels and universal materials. The EMU chip breaker geometry promotes positive rake cutting action, which reduces cutting forces and heat buildup during continuous turning. With an inscribed circle of 0.75 inches, an insert length of 0.75 inches, and an insert thickness of 0.25 inches, this is a full-size SNMG insert suited for medium to heavy turning depths. It fits standard SNMG-style toolholders using clamp and pin holding methods, common across most modern turning centers and lathe tool blocks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P grade with Al2O3 CVD coating for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eSNMG643EMU geometry with 90-degree square insert shape and neutral hand\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 4 degrees reduces cutting forces on workpiece\u003c\/li\u003e\n  \u003cli\u003eEMU chip breaker optimized for consistent chip control in steel turning\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin toolholder holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SNMG-style turning toolholders that accept clamp and pin insert retention. Compatible with workpiece material codes M and P covering steels and universal materials. ISO code SNMG190612N-MU confirms dimensional interchangeability with ISO 13399-compliant tooling systems. ANSI code SNMG643EMU applies for North American toolholder selection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before seating or replacing an insert. Ensure the insert pocket and clamp surfaces are clean and free of chips before installation, as debris under the insert seat affects cutting performance and tool life. Follow the toolholder manufacturer torque guidelines for the clamp screw to avoid insert fracture or improper seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SNMG643EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG190612N-MU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (90 degrees)\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: EMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 4 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inches (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inches (0.0469 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.3126 inches\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\u003eSecondary Workpiece Material Code\u003c\/strong\u003e: M, P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19RBALL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51727803842866,"sku":"19RBALL","price":352.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3fed8768921499ec66e902ef3594f04.jpg?v=1788682670","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rball-turning-insert-snmg643emu-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
