This solid carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability suited for moderate to high cutting speeds. The 80-degree diamond shape provides a strong cutting edge geometry, while the KR chip breaker controls chip flow during continuous and interrupted cuts. The neutral hand orientation makes it compatible with standard CCMT toolholders. It is sized at a 1\/2-inch inscribed circle with a 3\/16-inch insert thickness and a 1\/32-inch corner radius.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning cast iron workpieces in production and job-shop environments, corresponding to ISO material group K. The CoroTurn 107 series targets external turning with screw-clamped toolholders. Applications include finish and semi-finish turning where consistent surface quality and predictable tool life are required. The maximum depth of cut is 12.10 mm. This insert is sold individually, with a minimum order quantity of 10 units, making it suitable for shop stock replenishment or production line use by machining professionals and CNC operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated with TiCN, Al2O3, and TiN layers for wear resistance on cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with rounded cutting edge style for strength and versatility\u003c\/li\u003e\n  \u003cli\u003eKR chip breaker geometry controls chip evacuation during turning\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius suits semi-finish to finish turning applications\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped insert holding method for secure, repeatable seating in CCMT toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert extend usable tool life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-clamped CCMT-style toolholders within the CoroTurn 107 series.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturers specified torque; do not overtighten, as this can fracture the insert or damage the pocket seat. Inspect the toolholder pocket for debris or wear before seating a new insert to ensure proper contact and runout.\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 12 04 08-KR 3225\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3225\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KR\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\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.500 inches \/ 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inches \/ 0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches \/ 4.76 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 12.10 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 Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.54 inches x 1 inch x 0.19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 6868249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755033035058,"sku":"6868249","price":311.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5099b6416aa66127c34dc7fe454787ac_a62f6013-3bae-4d2b-846e-dbb5162ef193.jpg?v=1788950648","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6868249-turning-insert-ccmt432-kr-3225","provider":"Voomi Supply","version":"1.0","type":"link"}
