Carrying ANSI code CCMT431 and ISO code CCMT120404, this neutral-hand insert features an 80-degree diamond (rhombic) shape, a 7-degree relief angle, and a 0.40 mm (0.0157 inch) corner radius. The CVD coating and ACP25M grade designation provide high wear resistance across steel, stainless steel, and cast iron workpiece materials. It is held in the toolholder by screw clamping and delivers a positive side clearance geometry for clean, consistent chip evacuation on medium to finish turning passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for general-purpose turning in job shop, production machining, and maintenance repair environments. The WM+ chip breaker geometry is designed to handle a range of depths of cut up to 3.00 mm (0.1181 inches), making it practical for both roughing-to-finish and finishing passes on steel and stainless steel components. Cast iron turning applications also fall within the rated primary workpiece material codes (P, M, K). Machinists and CNC operators working with mid-range surface speeds and moderate feed rates will find this insert fits standard CCMT431-compatible toolholders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI code CCMT431 and ISO code CCMT120404 for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eCVD-coated ACP25M carbide grade rated for steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides two cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eWM+ chip breaker for controlled chip formation across varied feed rates\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance geometry reduces cutting forces on finish passes\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method for repeatable, rigid seating in the pocket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for CCMT431 (ISO CCMT120404) toolholders accepting a 0.5000-inch inscribed circle carbide insert with screw clamping.

Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque range — do not overtighten, as this can fracture the carbide. Inspect the insert pocket for chips or debris before seating the new insert. Verify tool offset compensation after indexing to a fresh cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT120404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\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: ACP25M\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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: 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: 0.2205 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\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: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: P, M, K\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: C\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: 0.02 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75331868\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738362675506,"sku":"75331868","price":195.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37d886f1b1c4d83ce6704a5ca171a231_3fa48df3-34ce-4c2e-809b-8568576c44fb.jpg?v=1788798651","url":"https:\/\/voomisupply.com\/products\/accupro-75331868-ccmt431-carbide-turning-insert-cvd","provider":"Voomi Supply","version":"1.0","type":"link"}
