It features a VBMT insert style with a 35-degree diamond shape and a neutral hand orientation. The insert carries a dual-layer PVD coating of TiAlN and AlCr2O3, providing heat and wear resistance at elevated cutting temperatures. With a 0.25-inch inscribed circle, an insert length of 0.428 inches, and a corner radius of 0.20 mm (0.0079 inches), this insert is engineered for finishing and semi-finishing passes where edge sharpness and surface finish are critical. It is held in place by screw clamping and fits toolholders with the corresponding VBMT pocket geometry.\u003c\/p\u003e\u003cp\u003eThis insert is primarily intended for turning stainless steel, with secondary suitability for superalloys and titanium. The MF chip breaker geometry is optimized for light to medium depths of cut on work materials that produce stringy, difficult-to-control chips. Typical applications include CNC lathe operations in aerospace, medical device, and general precision machining environments where consistent chip control and tight tolerances are required. The 1115 grade paired with PVD coating suits lower cutting speeds that protect the edge on work-hardening alloys. Each package contains one insert; the minimum order quantity is 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVBMT 35-degree diamond insert shape with neutral hand for versatile external turning setups\u003c\/li\u003e\n\u003cli\u003eDual PVD coating (TiAlN and AlCr2O3) for wear resistance on stainless steel and superalloys\u003c\/li\u003e\n\u003cli\u003eMF chip breaker geometry engineered for controlled chip formation on difficult materials\u003c\/li\u003e\n\u003cli\u003eScrew-clamping hold method (clearance code B, tolerance code M) for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for extended tool life per unit cost\u003c\/li\u003e\n\u003cli\u003eISO designation VBMT 11 03 02-MF 1115 for direct cross-reference to toolholder specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders accepting VBMT-style inserts with a screw-on clamping method.

Seat the insert fully into the VBMT pocket and torque the clamping screw according to the toolholder manufacturer specification for that pocket size. Inspect the insert seat and shim for chips or debris before seating to prevent micro-fracture of the cutting edge. Do not exceed the recommended depth of cut or feed rate for the 1115 grade on work-hardening materials, as catastrophic edge failure can occur without warning.\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\u003eISO Code\u003c\/strong\u003e: VBMT 11 03 02-MF 1115\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\u003eManufacturer Grade\u003c\/strong\u003e: 1115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eChip Breaker\u003c\/strong\u003e: MF\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: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.428 inches (10.87 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\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\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\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy, Titanium (ISO code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 5755521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51739312685362,"sku":"5755521","price":389.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3811f51d4a4029fe3d1c5c536f48ce28_e60270f1-055c-41b2-8d03-884c04135a27.jpg?v=1788812993","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5755521-turning-insert-vbmt220-mf","provider":"Voomi Supply","version":"1.0","type":"link"}
