It carries a VBMT insert style with a 35-degree diamond shape and a 5-degree relief angle, providing a sharp cutting geometry suited to finishing and semi-finishing passes. The insert features a CVD-applied multilayer coating of Al2O3, TiN, and TiCN under grade 4415, delivering thermal resistance and wear protection. With a 3\/8 inch inscribed circle and a 1\/32 inch corner radius, this neutral-hand insert is installed by machinists and CNC operators working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for machining steel and is also rated for cast iron applications. The PR chip breaker geometry controls chip flow effectively across a range of cutting depths and feed rates typical of finish turning. The VBMT 332-PR designation follows the ISO standard VBMT 16 04 08-PR 4415, making it straightforward to cross-reference against toolholder specifications. It is suitable for both high-volume production turning and precision single-part applications where consistent surface finish and dimensional accuracy are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer coating: Al2O3, TiN, and TiCN for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eGrade 4415 provides a balance of hardness and toughness for steel turning\u003c\/li\u003e\n  \u003cli\u003ePR chip breaker geometry promotes controlled chip evacuation during finishing and semi-finishing cuts\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape with 5-degree relief angle for low cutting forces and access in tight clearance conditions\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard VBMT toolholders using clamp or screw holding methods\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for cost efficiency in high-turnover tooling programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VBMT-style toolholders that accept a 3\/8 inch inscribed circle insert with a 0.1732 inch hole diameter and clamp or screw retention.

Seat the insert firmly against the toolholder pocket and tighten the clamp or screw to the toolholder manufacturer's specified torque. Inspect the insert seat and shim for debris or damage before seating to ensure repeatable tool nose position. Follow shop-specific lockout and tagout procedures before changing inserts on live tooling or gang-style turning centers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (35 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VBMT 16 04 08-PR 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: Al2O3, TiN, TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches \/ 0.79 mm)\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: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, 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 (Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches L x 2.13 inches W x 0.54 inches H\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7860518\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731939033394,"sku":"7860518","price":352.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3a0e04b39a426c04a646f93b21c3efd.jpg?v=1788736936","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860518-turning-insert-vbmt332-pr-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
