This insert features a 35-degree diamond (rhombic) shape with a positive side clearance and a neutral hand orientation. The multilayer CVD coating stack — TiCN, Al2O3, and TiN — delivers high wear resistance balanced with toughness, making it well suited for interrupted cuts and demanding stainless steel profiles. The MF chip breaker geometry is engineered specifically for finishing passes, producing controlled chip flow at light depths of cut and fine feed rates. Cutting edge count is 2 per insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in CoroTurn 107 toolholders and compatible screw-clamp boring bars and external turning tools. Its primary application is finish turning of stainless steel components in CNC lathe and turning center operations, both in job shop and production environments. The VBMT221 size code and ISO designation VBMT 11 03 04-MF 2025 allow direct cross-reference into toolholder catalogs for proper seat and clamping confirmation. Typical users include CNC machinists and toolroom technicians working with austenitic and duplex stainless grades where surface finish and dimensional control are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e35-degree diamond (V-shape) insert geometry with positive side clearance for low cutting forces on finishing passes\u003c\/li\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN — optimized for stainless steel wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry designed for finishing operations with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius (0.0156 inches) for fine surface finish requirements\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method provides secure seating and repeatable edge indexing\u003c\/li\u003e\n  \u003cli\u003e2 usable cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series screw-clamp toolholders accepting VBMT 11 03 04 inserts. Verify toolholder pocket designation matches the VBMT insert style and B clearance code before installation. ISO insert code VBMT 11 03 04-MF 2025 and ANSI insert code VBMT221 may be used for direct toolholder catalog cross-reference.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert replacement and indexing should be performed by a qualified CNC machinist or toolroom technician with the machine in a locked-out, zero-energy state per applicable machine-specific lockout-tagout procedures. Use the correct Torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the insert seat or the insert body. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Handle carbide inserts carefully; chipping can occur from contact with hard surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VBMT221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VBMT 11 03 04-MF 2025\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\u003eManufacturer Grade\u003c\/strong\u003e: 2025\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: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\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: 1\/4 inch (0.2500 inches \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4201 inches (10.67 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inches \/ 3.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches \/ 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\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: 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\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5755605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728765190450,"sku":"5755605","price":311.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c892c49314d5d9df6cf61de8084ec870_a6d675c1-56bf-4ca6-9813-710d45a52300.jpg?v=1788696001","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5755605-turning-insert-vbmt221-mf-2025","provider":"Voomi Supply","version":"1.0","type":"link"}
