This insert features a 35-degree diamond shape (V) with a neutral hand orientation, a 3\/8 inch inscribed circle, and a 1.19 mm corner radius. The substrate carries a CVD-applied multilayer coating of Al2O3, TiN, and TiCN under the manufacturer grade 4425, delivering wear resistance and thermal stability during continuous and interrupted steel cutting. Machinists and CNC lathe operators install this insert into compatible toolholders for production-volume turning work.\u003c\/p\u003e\u003cp\u003eThis insert is intended for primary use on steel workpieces and secondary use on cast iron. It fits typical production turning environments ranging from light finishing to moderate roughing passes. The PM chip breaker geometry is suited for medium-depth cuts where controlled chip formation is required. The insert holds four cutting edges, reducing per-edge tooling cost in high-throughput shop environments. Applicable in both CNC and manual lathe setups wherever VNMG-style toolholders are in use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35-degree diamond insert shape (V) with neutral hand orientation for versatile toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: Al2O3, TiN, and TiCN for heat and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 4425 solid carbide substrate optimized for steel and cast iron\u003c\/li\u003e\n\u003cli\u003e1.19 mm corner radius with PM chip breaker for controlled chip evacuation in medium cuts\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method compatible with standard VNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting VNMG-style inserts per ISO code VNMG 16 04 12-PM 4425.

Seat the insert fully against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the pocket and seating surface for chips or debris before seating a new cutting edge. Verify insert orientation and chip breaker direction before resuming the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V), 35-degree included angle\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: 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3, TiN, TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and 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: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VNMG 16 04 12-PM 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7860995\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51727401976114,"sku":"7860995","price":458.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/724ff43666559fa1a8c45cfd160d6bf8.jpg?v=1788677421","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860995-vnmg333-pm-4425-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
