It features a 35-degree diamond (rhombic) insert shape, a CVD coating applied over a carbide substrate, and a neutral hand orientation. The ACP25M grade delivers high wear resistance across steel, stainless steel, and cast iron workpiece materials. The WSF+ chip breaker geometry controls chip flow during finishing and light-roughing passes. With two cutting edges and a screw-holding method, this insert suits high-volume production environments where consistent tool life and surface finish are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) workpieces. It is sold individually but must be ordered in multiples of 10. Typical applications include shaft turning, facing, and contouring passes where a sharp 35-degree nose geometry is needed to access tight part features. It seats in VCMT-compatible toolholders following ANSI and ISO standard dimensions and is installed by licensed machinists and CNC setup technicians in precision machining shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVCMT insert style with 35-degree diamond (rhombic) shape for access to tight workpiece geometry\u003c\/li\u003e\n  \u003cli\u003eCVD coating on ACP25M carbide grade for high wear resistance in steel and stainless steel applications\u003c\/li\u003e\n  \u003cli\u003eWSF+ chip breaker optimized for finishing and light-roughing passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard VCMT-compatible right- and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance (clearance code C) reduces cutting forces and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert for extended tool life per unit cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to seat in VCMT-style toolholders conforming to ANSI insert code VCMT331 and ISO insert code VCMT160404.

Ensure the machine spindle is fully stopped and the tool is secured in the turret before indexing or replacing the insert. Use the correct torque driver or wrench for the clamping screw to avoid seat damage  -  consult the toolholder manufacturer specifications for the appropriate fastener torque. Inspect the insert pocket and seating surface for chips or wear before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VCMT331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VCMT160404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C (Positive Side Clearance)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3752 inches (9.53 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: 0.1732 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0886 inches (2.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACP25M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WSF+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 75511527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740312699186,"sku":"75511527","price":220.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39c2854156ac52f7b994e775d0b3cd24_f77925c0-8b21-4688-9066-5fdee96f095d.jpg?v=1788824213","url":"https:\/\/voomisupply.com\/products\/accupro-75511527-turning-insert-vcmt331-cvd-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
