Designated grade AC630M with a CVD-applied Al2O3 coating, this insert is engineered for turning operations on steel and stainless steel workpieces. It features an 80-degree diamond insert shape, a 5\/8-inch inscribed circle, a 3\/64-inch corner radius, and a 1\/4-inch insert thickness. The neutral rake and neutral hand geometry make it suitable for a broad range of turning applications. Machinists and CNC operators working in production or job-shop environments will find this insert compatible with standard CNMG toolholders using clamp and pin holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is applied in external and internal turning operations where consistent surface finish and dimensional accuracy are required. The AC630M grade with Al2O3 CVD coating is well-suited for machining carbon steel and stainless steel at moderate to high cutting speeds. The EEG chip breaker geometry is designed to manage chip flow effectively during continuous turning cuts. It is commonly used in CNC lathes and turning centers in automotive, aerospace, and general machining environments where reliable tool life on ferrous materials is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with CVD-applied Al2O3 coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (ANSI code CNMG543EEG, ISO code CNMG160612N-EG)\u003c\/li\u003e\n\u003cli\u003e5\/8-inch (0.6250 inch) inscribed circle for precise seating in standard CNMG toolholders\u003c\/li\u003e\n\u003cli\u003e3\/64-inch (0.0469 inch) corner radius for balanced edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eEEG chip breaker geometry for controlled chip evacuation in steel and stainless steel turning\u003c\/li\u003e\n\u003cli\u003eNeutral rake and neutral hand designation for versatile application across multiple toolholder orientations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for CNMG-style toolholders using clamp and pin holding methods with a 1\/4-inch hole diameter.

Ensure the machine spindle is fully stopped and the toolholder is removed or safely secured before replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamp for wear or debris before installing a new insert to ensure proper seating and clamping force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG543EEG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160612N-EG\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\/Finish\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: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0469 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6339 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 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: EEG\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\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: 0.048 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: 19PWCGM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51734891888946,"sku":"19PWCGM","price":39.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0fda9bccd3858dabcd8398c9b6f7ea53_bf21e0bb-c8cb-4c5f-a51d-5c61e36dac3b.jpg?v=1788767682","url":"https:\/\/voomisupply.com\/products\/sumitomo-19pwcgm-cnmg543eeg-ac630m-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
