It features a 35-degree diamond insert shape with a 5-degree relief angle and a 0.20 mm (0.0079 inch) corner radius. The insert carries a TiAlN and AlCr2O3 dual-layer coating applied via PVD process, delivering thermal resistance and edge durability during steel and multi-material cutting. With two usable cutting edges per insert, it is suited for high-efficiency finishing and semi-finishing passes. Machinists and toolroom professionals specify this insert for its precise geometry control under the UF chip breaker designation, which is optimized for light cuts and fine surface finishes.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for use in the CoroTurn 107 tooling system. Its primary workpiece material designation is steel (ISO code P), and it is also rated for stainless steel, non-ferrous metals, superalloys, and titanium (ISO codes M, N, S). Typical applications include shaft turning, facing, and profiling on CNC turning equipment in job shop, production, and aerospace machining environments. The neutral hand orientation allows flexible use in both right-hand and left-hand toolholder configurations where the VBMT seat geometry is present.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN and AlCr2O3 PVD coating for extended tool life across steel and difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (V) with UF chip breaker for controlled chip formation during light finishing cuts\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius provides fine surface finish capability with reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert maximize value per piece\u003c\/li\u003e\n  \u003cli\u003eGrade 1125 carbide substrate balances wear resistance and toughness for multi-material versatility\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method ensures repeatable seating and rigid clamping in CoroTurn 107 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroTurn 107 series toolholders that accept the VBMT insert style with a screw-on clamping method.

Use the appropriate Torx or hex key to seat and torque the clamping screw per the toolholder manufacturer specification for the CoroTurn 107 pocket. Inspect the insert seat and pocket for chips or debris before seating the new insert. Do not use the insert beyond visible edge wear or chipping, as degraded cutting edges increase cutting forces and reduce workpiece quality.\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\u003eISO Code\u003c\/strong\u003e: VBMT 11 02 02-UF 1125\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 35 Degree (V)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UF\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCr2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 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: 0.0938 inches (2.38 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Non-Ferrous Metal, Superalloy, Titanium\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\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 5755495\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51743392071986,"sku":"5755495","price":387.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41dcb7c1bff5aab973b0e4501453ab2a_a9dcbe2c-e88e-4822-b8fc-67512696d053.jpg?v=1788846548","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5755495-turning-insert-vbmt21-50-uf","provider":"Voomi Supply","version":"1.0","type":"link"}
