Manufactured to grade AC630M with a CVD-applied aluminum oxide (Al2O3) coating, this insert delivers thermal resistance and wear performance suitable for steel and stainless steel turning applications. The square SNMG insert shape features a neutral hand orientation, a 90-degree included angle, a 0-degree relief angle (Clearance Code N), and a positive rake angle of 4 degrees. The EMU chip breaker geometry promotes controlled chip formation during continuous and semi-interrupted cuts. Machinists and CNC operators in production and job-shop environments are the primary installers of this insert type.\u003c\/p\u003e\u003cp\u003eThis turning insert is suited for finishing and semi-finishing operations on steel and stainless steel workpieces. The AC630M grade with Al2O3 CVD coating is formulated for ISO M and P material groups, making it a practical choice for general-purpose external and internal turning where consistent edge life and surface finish are priorities. It seats into standard SNMG-style toolholders using clamp and pin holding methods, fitting into the SN series toolholder family. The insert conforms to both ANSI (SNMG543EMU) and ISO 13399 (SNMG150612N-MU) designations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC630M grade with CVD aluminum oxide (Al2O3) coating for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003eSquare insert shape with 90-degree included angle and 0-degree relief (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003eEMU chip breaker geometry for controlled chip evacuation in steel and stainless steel turning\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 4 degrees reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eDual-standard compliance: ANSI SNMG543EMU and ISO 13399 SNMG150612N-MU\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible with standard SNMG SN-series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard SNMG-style toolholders that accept clamp and pin insert retention.

Inspect the toolholder pocket and clamp hardware for wear or debris before seating a new insert. Torque clamp screws according to the toolholder manufacturer specifications — do not use impact tools on insert clamping hardware. Verify insert orientation and hand before resuming a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SNMG543EMU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG150612N-MU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC630M\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: Aluminum Oxide (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 (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\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\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\u003eInsert Length\u003c\/strong\u003e: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0469 inches (3\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 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\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 19PWALJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51754009559346,"sku":"19PWALJ","price":269.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3fed8768921499ec66e902ef3594f04_1547da4d-21ec-4149-b842-5062ef5ce413.jpg?v=1788942852","url":"https:\/\/voomisupply.com\/products\/sumitomo-19pwalj-turning-insert-snmg543emu-ac630m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
