It carries ANSI insert code VCMT331 and ISO code VCMT160404, making it a direct cross-reference in standard tooling systems. The insert features a 35-degree diamond (rhombic) V-shape with a 7-degree relief angle and a 0.40 mm (0.0157 inch) corner radius. The CVD coating and ACM20P grade deliver high wear resistance with moderate toughness. The insert is held by screw clamping and has a positive side clearance geometry, contributing to clean chip formation on both steel and stainless steel workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finish and semi-finish turning of steel (ISO P) and stainless steel (ISO M) materials in production and job-shop environments. The WSF+ chip breaker geometry supports controlled chip evacuation across a range of feed rates and depths of cut up to 2.25 mm (0.0886 inch). It is typically installed by machinists and CNC tooling technicians in both high-volume production cells and prototype turning work. The neutral hand orientation allows flexible use in both left- and right-hand toolholders that accept VCMT-style inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI code VCMT331 and ISO code VCMT160404 for standardized cross-referencing\u003c\/li\u003e\n  \u003cli\u003eCVD-coated ACM20P carbide grade rated for high to moderate wear resistance on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (V-shape) insert geometry with 7-degree relief angle and positive side clearance\u003c\/li\u003e\n  \u003cli\u003eWSF+ chip breaker for controlled chip formation across varying cutting parameters\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method with 0.1732 inch hole diameter for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for extended service life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw-on replacement insert for VCMT-style toolholders accepting ANSI VCMT331 or ISO VCMT160404 inserts.

Before changing inserts, confirm the machine is in E-stop or powered down and the spindle is fully stopped. Use the correct Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert seat and clamping components for chips or damage before seating a new insert to ensure proper contact and runout.\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 degrees\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\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 4.76 mm (0.1874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.3752 inches)\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: 2.25 mm (0.0886 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACM20P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WSF+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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: 75282731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747042591026,"sku":"75282731","price":244.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c40ea9497df1bdd5442c9fec2a6a3eb0_b643adb7-b948-4338-adc5-ec19195c2ce6.jpg?v=1788875536","url":"https:\/\/voomisupply.com\/products\/accupro-75282731-vcmt-turning-insert-carbide-cvd-vcmt331","provider":"Voomi Supply","version":"1.0","type":"link"}
