The insert is manufactured from solid carbide and carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers wear resistance and thermal stability during continuous cutting. The insert shape is an 80-degree diamond (C-shape), and the neutral hand orientation makes it suitable for both right- and left-hand toolholders in the matching CCMT pocket style. Chip control is handled by the KR chip breaker geometry, which is optimized for cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for medium to finish turning applications in cast iron (ISO material group K). The CoroTurn 107 series is widely used in production environments where secure screw clamping and consistent edge positioning are required. With a maximum depth of cut of 8.87 mm, this insert handles both light finishing passes and moderate roughing cuts on ferrous materials. It is installed by licensed machinists and CNC operators as a direct drop-in for CCMT 09 T3 08-KR 3225 toolholder pockets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life in cast iron cutting\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with 7-degree relief angle for positive clearance\u003c\/li\u003e\n  \u003cli\u003eKR chip breaker geometry engineered for cast iron chip control\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method ensures repeatable seating and edge indexing\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert with rounded cutting edge style\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 8.87 mm supports light roughing through finish turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis insert is identified by ISO code CCMT 09 T3 08-KR 3225 and fits CCMT-style toolholders with the corresponding pocket geometry.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key specified by the toolholder manufacturer to secure the clamping screw — do not overtighten. Inspect the toolholder pocket for chips or wear before seating the new insert to ensure proper contact and edge repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 09 T3 08-KR 3225\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: 3225\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches \/ 0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches \/ 3.97 mm)\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 8.87 mm\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: Cast Iron (ISO Group K)\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: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 6868242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744825901362,"sku":"6868242","price":207.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5099b6416aa66127c34dc7fe454787ac_7e576547-ca2c-433f-aa26-10a0b7c90d2c.jpg?v=1788861061","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6868242-turning-insert-ccmt32-52-kr","provider":"Voomi Supply","version":"1.0","type":"link"}
