It features a CVD coating and an 80-degree diamond (rhombic) insert shape, giving it strong nose strength and versatility across a broad range of workpiece materials. The corner radius measures 0.40 mm (0.0157 inches) and insert thickness is 0.1874 inches (4.76 mm). With four cutting edges and a neutral hand orientation, this insert delivers consistent performance in production turning operations. It is suited for machinists running steel, stainless steel, and cast iron at varying removal rates.\u003c\/p\u003e\u003cp\u003eThis insert is intended for general-purpose and production turning on CNC and manual lathes. The CNMG431 geometry with WM+ chip breaker is well-matched to moderate to high material removal rates on steel and stainless steel, and moderate removal on cast iron. The grade ACP15K with CVD coating targets high wear resistance to moderate toughness across P, M, and K work material categories. It fits toolholders designed for CNMG-style inserts using clamp, lever lock, pin, or screw holding methods.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-coated carbide grade ACP15K for wear resistance across steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape provides strong cutting edge and versatile entry angles\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker geometry supports a wide range of feed and depth-of-cut conditions\u003c\/li\u003e\n\u003cli\u003eNegative side clearance (N clearance code) with M tolerance for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, lever lock, pin, and screw-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit CNMG431 (ISO: CNMG120404) toolholders using clamp, lever lock, pin, or screw holding methods.

Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench or driver specified by the toolholder manufacturer when securing the clamping screw or lever lock — do not overtighten by hand estimation. Inspect the insert pocket and seating surfaces for chips or debris before seating a new edge to ensure accurate positioning and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\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\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 75542977\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729148248370,"sku":"75542977","price":176.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a9114a8ca4a9902a74a2216554f61331.jpg?v=1788700876","url":"https:\/\/voomisupply.com\/products\/accupro-75542977-cnmg431-carbide-turning-insert-cvd","provider":"Voomi Supply","version":"1.0","type":"link"}
