It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and extended tool life. The insert has an 80-degree diamond shape with a neutral hand orientation, a 1\/2-inch inscribed circle, and a 1\/32-inch corner radius. With a KM chip breaker geometry, it is engineered to produce manageable chips and maintain consistent surface finish. It is part of the CoroTurn 107 series and is installed by machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is optimized for turning cast iron workpieces, classified under primary workpiece material code K. The CoroTurn 107 series targets finishing and light roughing passes where dimensional accuracy and surface integrity are critical. The screw-holding method provides rigid clamping in standard CCMT toolholders. With two cutting edges per insert, it offers an economical cost-per-edge ratio for medium to high-volume turning operations. Typical applications include shaft turning, facing, and profiling on gray, ductile, and compacted graphite iron components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eKM chip breaker geometry engineered for cast iron chip control\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with rounded cutting edge style\u003c\/li\u003e\n\u003cli\u003e1\/32-inch corner radius for controlled edge engagement and surface finish\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for extended tool life per piece\u003c\/li\u003e\n\u003cli\u003eScrew-mounted clamping compatible with standard CCMT toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CCMT-style toolholders within the Sandvik Coromant CoroTurn 107 turning system.

Power down and de-energize the machine before changing inserts, and follow the machine tool manufacturer's lockout\/tagout procedure. Use the correct Torx or hex key specified by the toolholder manufacturer to seat the clamping screw. Inspect the toolholder seat for debris or wear before seating a new insert to ensure proper support and indexing accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\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 Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\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\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: KM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Rounded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 (Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 12.10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inches (5.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT 12 04 08-KM 3225\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.54 inches wide x 1 inch long x 0.19 inches high\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 6868248\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744839500082,"sku":"6868248","price":309.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28c9430d43e17b61805bf294c76b621f_ec8faeed-aa42-4ec2-b3b5-5091ea245885.jpg?v=1788861314","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6868248-turning-insert-ccmt432-km-3225","provider":"Voomi Supply","version":"1.0","type":"link"}
