It carries the ANSI code VCMT331 and ISO code VCMT160404, with a 35-degree diamond (rhombic) insert shape and a 7-degree relief angle. The insert is manufactured in grade ACP25M with a CVD coating, delivering high wear resistance across a range of workpiece materials including steel, stainless steel, and cast iron. The neutral hand orientation and positive side clearance make it a versatile choice for finish and semi-finish turning passes where edge geometry and surface finish consistency matter.\u003c\/p\u003e\u003cp\u003eThis insert is suited for light to moderate turning applications on CNC turning centers and manual lathes in production and job-shop environments. The WM+ chip breaker geometry is optimized for controlled chip formation during continuous and interrupted cuts on steel, stainless, and cast iron components. The screw-clamping holding method provides secure seating in compatible VCMT toolholders. With a maximum depth of cut of 0.1181 inches and a corner radius of 0.0157 inches, this insert is best applied to finishing and light roughing passes requiring tight dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code VCMT331 and ISO code VCMT160404 for direct cross-reference and toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCVD-coated ACP25M carbide grade for high wear resistance on steel (P), stainless steel (M), and cast iron (K) workpieces\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape with 7-degree relief angle and positive side clearance for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker geometry for consistent chip control in finish and semi-finish turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard VCMT-style toolholders without orientation constraints\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method ensures repeatable insert seating and edge positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VCMT-style screw-clamp turning toolholders conforming to ANSI VCMT331 and ISO VCMT160404 standards.

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 substrate. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Always verify tool offset and take a light test cut before returning to full production depths.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\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\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 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: 0.1181 inches (3.00 mm)\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 Codes\u003c\/strong\u003e: P (Steel), M (Stainless Steel), K (Cast Iron)\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\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: 75287151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727707963698,"sku":"75287151","price":221.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a7d5340636e7bdccbb9e8f8f9bf45.jpg?v=1788681099","url":"https:\/\/voomisupply.com\/products\/accupro-75287151-vcmt331-cvd-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
