Manufactured under the Isoturn series, this insert features a multilayer PVD coating of TiCN, Al2O3, and TiN applied over a solid carbide substrate, delivering wear resistance and thermal stability during interrupted and continuous cuts. The 80-degree diamond insert shape (shape code C) provides a sharp, rigid cutting geometry with a positive rake angle and a 7-degree relief angle (clearance code C). The WG chip breaker geometry promotes controlled chip flow and reduced cutting forces. Insert length measures 9.70 mm (0.382 inches) with an inscribed circle of 3\/8 inches (0.375 inches) and a corner radius of 1\/64 inches (0.0157 inches). Installed by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning stainless steel and steel workpieces in both roughing and finishing passes where controlled chip formation is critical. The IC8250 grade and multilayer coating make it effective in moderate to high cutting speed applications on stainless steel (ISO material group M) and carbon or alloy steel (ISO material group P). The screw-holding method and tolerance code M ensure repeatable seating in compatible CCMT insert pockets. Maximum depth of cut is 2.00 mm (0.0787 inches). Typical applications include shaft turning, facing, and profiling on production lathes in metalworking and manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiCN, Al2O3, and TiN multilayer coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with positive rake and 7-degree relief angle for efficient cutting geometry\u003c\/li\u003e\n\u003cli\u003eWG chip breaker geometry for controlled chip evacuation on stainless steel and steel\u003c\/li\u003e\n\u003cli\u003eInscribed circle of 3\/8 inches with 1\/64-inch corner radius for precise edge definition\u003c\/li\u003e\n\u003cli\u003eScrew-held mounting with tolerance code M for consistent, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards for integration with CAM and tooling management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CCMT-style insert pockets within the ISCAR Isoturn series toolholders.

Power down and lock out the machine before changing inserts. Use the correct torque wrench and manufacturer-specified clamping screw to seat the insert without over-tightening. Inspect the insert pocket for chips or debris before seating to ensure full contact and accurate tool offset.\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\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\u003eManufacturer Grade\u003c\/strong\u003e: IC8250\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: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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 Holding Method\u003c\/strong\u003e: Screw\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\/64 inches (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.70 mm (0.382 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\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: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: M, P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.104 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5550219\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746816491826,"sku":"5550219","price":235.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbed027a338bd233a441306076f5c3a5.jpg?v=1788873794","url":"https:\/\/voomisupply.com\/products\/iscar-5550219-ccmt31wg-ic8250-turning-insert-isoturn","provider":"Voomi Supply","version":"1.0","type":"link"}
