Built to ANSI code SNMG433 and ISO code SNMG120412, it features a square insert shape with a 90-degree included angle and negative side clearance geometry. The CVD coating and ACP15K grade deliver high wear resistance balanced with toughness, making it suitable for steel, stainless steel, and cast iron applications. With 8 available cutting edges, this insert offers extended tool life and a lower per-edge cost in production environments. Installed by machinists and tooling technicians, it fits standard SNMG toolholders using clamp, lever lock, pin, or screw holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is suited for medium to finishing cuts on steel (P), stainless steel (M), and cast iron (K) workpieces. The WM+ chip breaker geometry supports controlled chip formation across a range of feed rates and depths of cut up to 0.1575 inches (4.00 mm). It is well-matched for production turning on CNC machining centers and manual engine lathes in job shop and high-volume manufacturing settings. The neutral hand orientation allows use in a wide variety of toolholder configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI SNMG433 and ISO SNMG120412 standardized geometry for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCVD coating with ACP15K grade for high wear resistance and toughness on P, M, and K workpiece materials\u003c\/li\u003e\n\u003cli\u003e8 cutting edges per insert for reduced per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker for controlled chip formation in medium to finishing turning operations\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.1575 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003eNegative side clearance with M tolerance code for reliable, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for SNMG433 and SNMG120412 style toolholders accepting square carbide turning inserts with a 0.5000-inch inscribed circle.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert key specified by the toolholder manufacturer when securing the clamping screw or lever lock — do not overtighten. Inspect the toolholder pocket and seating surface for chips or wear before seating a new insert to ensure proper indexing and edge engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNMG433\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNMG120412\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACP15K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0472 inches (1.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Lever Lock, Pin, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75257188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733146206514,"sku":"75257188","price":178.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3749209a008bbad35ea173395ed0f0ff.jpg?v=1788751883","url":"https:\/\/voomisupply.com\/products\/accupro-75257188-snmg433-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
