It carries a dual-layer PVD coating of TiAlN and AlCr2O3, which delivers heat resistance and edge wear protection at elevated cutting speeds. The insert features a 35-degree diamond shape, a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and a neutral hand orientation. It belongs to the CoroTurn 107 series and uses a screw-holding method. Machinists and CNC operators working with steel, stainless steel, superalloy, and titanium workpieces will find the MF chip breaker geometry well suited to light-to-medium finishing cuts.\u003c\/p\u003e\u003cp\u003eThis insert is intended for precision turning of steel and related difficult-to-machine materials in both production and job-shop environments. The MF chip breaker is optimized for finishing passes where consistent chip control and surface finish are the priority. The VBMT geometry with a 5-degree relief angle suits positive-rake toolholders commonly used in light turning applications. It is a per-piece sale with a minimum order quantity of 10 units. Applications include external longitudinal turning and facing on CNC lathes in industrial and aerospace machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD-coated TiAlN and AlCr2O3 dual-layer coating for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape (Shape Code V) provides a sharp, low-cutting-force geometry\u003c\/li\u003e\n\u003cli\u003eMF chip breaker designed for finishing operations with controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard VBMT screw-lock toolholders\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert maximize value per piece\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method (Clearance Code B, Tolerance Code M) for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VBMT-style screw-lock toolholders within the CoroTurn 107 series.

Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Seat the insert fully against the toolholder pocket faces before tightening the clamping screw to avoid micro-movement under cutting load. Inspect the insert pocket and screw threads for chips or damage each time the insert is indexed to the fresh cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\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: 1125\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: TiAlN, AlCr2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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 Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF\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\/64 inches (0.0156 inches \/ 0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.638 inches (16.21 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003eISO Code\u003c\/strong\u003e: VBMT 16 04 04-MF 1125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloy, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.26 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5755649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51753056895282,"sku":"5755649","price":332.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3811f51d4a4029fe3d1c5c536f48ce28_2b1c41ee-bef8-4d63-804c-fa8c234d1ca7.jpg?v=1788932491","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5755649-turning-insert-vbmt331-mf-1125","provider":"Voomi Supply","version":"1.0","type":"link"}
