Part of the CoroTurn 107 series, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering strong wear resistance and thermal stability at the cutting edge. The 35-degree diamond insert shape (Shape Code V) provides a sharp, acute cutting geometry suited for profiling and finishing operations. With a 0.25-inch inscribed circle and a 0.0156-inch corner radius, this insert is sized for light to medium depth-of-cut passes where edge sharpness and surface finish are the priority. It is installed via screw-holding method and carries a neutral hand designation, making it straightforward to spec into standard VBMT toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary use on stainless steel workpieces (ISO Material Code M), where the MF chip breaker geometry promotes controlled chip formation and reduced cutting forces during finishing and semi-finishing passes. The CoroTurn 107 series is a widely used platform in production turning environments, and Grade 2220 is a recognized Sandvik Coromant designation for CVD-coated carbide suited to stainless and similar difficult-to-machine materials. Typical applications include external profiling, facing, and light roughing on CNC lathes running stainless steel components in industrial and precision manufacturing settings. This insert is handled and installed by machinists and CNC operators in tool rooms and production cells.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond shape (VBMT) for sharp entry angles on profiling and finishing cuts\u003c\/li\u003e\n  \u003cli\u003eMF chip breaker geometry promotes controlled chip formation on stainless steel\u003c\/li\u003e\n  \u003cli\u003eScrew-holding method for secure, repeatable insert indexing in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral hand designation fits standard VBMT toolholder setups without handedness restriction\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for indexable use and extended tool life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VBMT-style screw-clamped turning toolholders compatible with the CoroTurn 107 platform.

Use the appropriate Torx or hex key for the clamping screw as specified by the toolholder manufacturer — do not over-torque or use impact tools on the insert screw. Inspect the insert pocket seat for debris or damage before seating a new insert, as contamination will affect edge height and surface finish accuracy. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.\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-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: V\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: 2220\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: TiCN, Al2O3, TiN (CVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VBMT 11 03 04-MF 2220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches (3.17 mm)\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\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 Hand\u003c\/strong\u003e: Neutral\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\u003c\/strong\u003e: Stainless Steel (ISO Code M)\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: 0.01 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: 7231481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51734275686706,"sku":"7231481","price":321.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94540496c6db41e3cdc9f64a076280fd_b9f66aa0-1b25-4c79-a43a-6513c002c447.jpg?v=1788762069","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7231481-turning-insert-vbmt221-mf-2220","provider":"Voomi Supply","version":"1.0","type":"link"}
