This indexable insert is manufactured from solid carbide and features a multilayer CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance, thermal stability, and oxidation protection during cutting. It carries a neutral hand orientation and a 35-degree diamond insert shape, giving it a sharp, low-contact geometry suited for finishing and semi-finishing passes. The manufacturer grade is 2220, optimized for cutting stainless steel and other ISO M-category workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in stainless steel turning applications where surface finish and tool life consistency are critical. The CoroTurn 107 series is commonly used in light-to-medium-duty external turning, profiling, and copying operations on CNC equipment. The MM chip breaker geometry is designed to manage chip flow and reduce built-up edge when machining austenitic and other difficult-to-cut stainless alloys. It is typically installed and indexed by machinists, toolroom technicians, and CNC setup operators working in production or job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiN for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape (V) for low cutting forces and profiling capability\u003c\/li\u003e\n\u003cli\u003eMM chip breaker geometry optimized for stainless steel chip control\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 2220 targets ISO M primary workpiece materials\u003c\/li\u003e\n\u003cli\u003eScrew-held insert mounting for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders accepting VCMT-style inserts with a screw-clamp holding method, clearance code C, and tolerance code M.

Use the appropriate Torx or hex key torque driver specified by the toolholder manufacturer to seat the clamping screw. Inspect the insert pocket and seating surface for chips or debris before indexing to a fresh cutting edge. Follow the toolholder manufacturer's clamping torque guidance to avoid insert fracture or pocket damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VCMT\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\u003eManufacturer Grade\u003c\/strong\u003e: 2220\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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\u003eInsert Material\u003c\/strong\u003e: Carbide\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: MM\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\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: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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\u003eISO Code\u003c\/strong\u003e: VCMT 11 03 04-MM 2220\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: 0.01 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: 7231492\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51732675690802,"sku":"7231492","price":335.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9715f6c5383748fef286713b5ed06424.jpg?v=1788745625","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7231492-turning-insert-vcmt221-mm-2220","provider":"Voomi Supply","version":"1.0","type":"link"}
