This SNMG432 EMU insert carries the AC830P grade designation and features an aluminum oxide (Al2O3) coating applied via CVD process, delivering a balance of moderate wear resistance and toughness suited to steel and stainless steel workpieces. The 90-degree square insert geometry with a neutral hand orientation fits standard SNMG-style toolholders. With a 0.5-inch inscribed circle and a 0.03125-inch corner radius, the 19RBAFG is built for light to medium machining passes where consistent edge integrity matters. Licensed machinists and CNC operators will recognize the EMU chip breaker designation as optimized for controlled chip flow in these material categories.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning operations on steel (ISO material group P) and stainless steel (ISO material group M) in both light and medium machining duty cycles. The EMU chip breaker geometry promotes effective chip control during finishing and semi-finishing passes. Typical installation settings include production turning on horizontal and vertical CNC lathes. The insert suits applications where tool life consistency across multi-pass runs is a priority, particularly when transitioning between P and M workpiece materials without a toolholder change.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P grade with CVD Al2O3 coating for moderate wear resistance and toughness in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eEMU chip breaker geometry rated for light and medium machining operations\u003c\/li\u003e\n  \u003cli\u003e90-degree square insert shape (ANSI code SNMG432, ISO code SNMG120408) with neutral hand\u003c\/li\u003e\n  \u003cli\u003e0.03125-inch corner radius for semi-finishing surface finish requirements\u003c\/li\u003e\n  \u003cli\u003eNegative side clearance with positive rake angle (4 degrees) for stable cutting forces\u003c\/li\u003e\n  \u003cli\u003eCompatible with both clamp and pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards for insert geometry and identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SNMG-style turning toolholders accepting a 432 ANSI size code insert.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for clamp screws to avoid insert seat damage — do not overtighten by hand. Inspect the insert pocket and shim seat for wear or debris before seating a new insert, as contamination in the pocket affects insert stability and surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNMG432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNMG120408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Full Code\u003c\/strong\u003e: SNMG120408N-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 (Aluminum Oxide)\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: S - Square, 90 degrees included angle\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\u003eChip Breaker Operation\u003c\/strong\u003e: Light Machining, Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03125 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Negative Side Clearance)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 4 degrees (Positive)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 19RBAFG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51747796058418,"sku":"19RBAFG","price":183.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3fed8768921499ec66e902ef3594f04_58afeab7-713a-4ec3-829d-81ec175dfe7d.jpg?v=1788885579","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rbafg-turning-insert-snmg432-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
