It carries ANSI insert code VCMT331 and ISO insert code VCMT160404. The insert features a 35-degree diamond (rhombic) shape, a 7-degree relief angle, and a PVD coating applied over a carbide substrate. Grade ACM25P with the WM+ chip breaker geometry gives this insert a working range that spans steel, stainless steel, and special and super alloys. A neutral hand orientation suits it for both OD turning and facing operations. Machinists and CNC operators working in job shop, production, or aerospace environments are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external turning, light finishing, and profiling applications where a sharp, positive-clearance geometry is required. The 35-degree included angle allows access to tight shoulders and contoured workpieces. The WM+ chip breaker is optimized for medium finishing cuts on steel (ISO P), stainless steel (ISO M), and special or super alloys (ISO S). A maximum depth of cut of 0.1181 inches (3.00 mm) defines the upper limit for material removal per pass. The screw-clamp holding method provides secure seating in compatible VCMT toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI code VCMT331 and ISO code VCMT160404 for cross-reference compatibility\u003c\/li\u003e\n  \u003cli\u003ePVD-coated carbide substrate, grade ACM25P, for high wear resistance across P, M, and S workpiece materials\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape allows profiling and shoulder turning in restricted clearance zones\u003c\/li\u003e\n  \u003cli\u003eWM+ chip breaker geometry supports steel, stainless steel, and special and super alloys\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance and 7-degree relief angle reduce cutting forces and edge buildup\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for rigid, repeatable seating in standard VCMT holders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for VCMT331 or VCMT160404 insert seats in standard screw-clamp VCMT toolholders.

Use the appropriate Torx or hex key specified by the toolholder manufacturer to tighten the clamping screw to the recommended seating torque per that manufacturer's documentation. Inspect the insert pocket and shim for wear or debris before seating a new insert. Never exceed the maximum depth of cut specification for this insert geometry, as doing so can cause premature edge fracture or toolholder damage.\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\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\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: ACM25P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: PVD\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 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: 3.00 mm (0.1181 inches)\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\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Special and Super Alloys (S)\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: 75264929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727801647410,"sku":"75264929","price":220.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a7d5340636e7bdccbb9e8f8f9bf45_7f4913df-512a-4e48-99bd-ee802dbc8922.jpg?v=1788682648","url":"https:\/\/voomisupply.com\/products\/accupro-75264929-turning-insert-vcmt331-carbide-pvd","provider":"Voomi Supply","version":"1.0","type":"link"}
