This solid carbide insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which builds heat and wear resistance at the cutting zone. It features an 80-degree diamond insert shape with a neutral hand orientation, a 3\/8-inch inscribed circle, and a 1\/64-inch corner radius. The KM chip breaker geometry is designed to control chip flow and reduce cutting forces during finishing and semi-finishing passes. Installed by machinists and CNC operators in production and job-shop environments, this insert fits screw-clamped toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning cast iron and similar K-group workpiece materials in both production and job-shop settings. The CoroTurn 107 series is a common platform used on screw-clamp toolholders in a wide range of CNC turning applications. The KM chip breaker geometry performs well in finishing and light semi-finishing cuts where controlled chip evacuation and surface finish are priorities. With a maximum depth of cut of 9.27 mm and 2 usable cutting edges per insert, this grade offers reliable tool life on cast iron components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for enhanced wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CCMT) with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eKM chip breaker geometry optimized for cast iron finishing and semi-finishing\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch (0.0156-inch) corner radius for controlled surface finish\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method compatible with CoroTurn 107 toolholders\u003c\/li\u003e\n  \u003cli\u003e2 usable cutting edges per insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series screw-clamp toolholders.

Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer specification. Inspect the insert seat and shim for debris or damage before seating the new insert, as contamination in the pocket can cause premature edge failure or poor surface finish.\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\u003eInsert Shape\u003c\/strong\u003e: Diamond (80-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3225\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: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inch \/ 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch \/ 3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 9.27 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\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\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 09 T3 04-KM 3225\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: 0.2 pounds\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: 6868237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728545120562,"sku":"6868237","price":223.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c9430d43e17b61805bf294c76b621f_40493bd6-b21a-4cf4-9fbd-fdc1592744bd.jpg?v=1788693067","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6868237-turning-insert-ccmt-coroturn-107","provider":"Voomi Supply","version":"1.0","type":"link"}
