It features a solid carbide substrate with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under the IC6025 manufacturer grade. This combination delivers wear resistance and thermal stability suited to demanding cutting conditions. The insert carries an 80-degree diamond shape, a positive rake geometry, and a 7-degree relief angle. At 9.70 mm in length with a 3\/8-inch inscribed circle, it fits standard CCMT toolholders and is installed by licensed machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is rated for stainless steel as its primary workpiece material, making it appropriate for aerospace, food service, and medical component machining where stainless grades dominate. The SM chip breaker geometry supports boring and chamfering operations. Maximum depth of cut is 0.098 inches (2.49 mm). The screw-clamp holding method is standard for CCMT-seat toolholders. It is a single-end insert, so each edge is used once before indexing or replacement. The Isoturn series designation places it within ISCAR's general turning insert family, conforming to ISO 13399 standards for tool data representation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC6025 grade solid carbide with CVD-applied TiCN, Al2O3, and TiN multilayer coating\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (shape code C) with positive rake and 7-degree relief angle\u003c\/li\u003e\n\u003cli\u003eSM chip breaker supports boring and chamfering applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 1\/64-inch corner radius for light-radius finishing cuts\u003c\/li\u003e\n\u003cli\u003eScrew-clamp seating method for rigid, repeatable insert location in CCMT toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for CCMT-seat turning toolholders accepting a 3\/8-inch inscribed circle.

Shut down spindle power and engage the machine lock before changing any insert. Use the correct Torx or hex key to seat the clamping screw to the toolholder manufacturer specification — do not overtighten, as this can fracture the carbide substrate. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper flatness and clamping.\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\u003eISO Code\u003c\/strong\u003e: CCMT 3-1-SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC6025\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 (CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0160 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.70 mm (0.3820 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1560 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1730 inches (4.39 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.098 inches (2.49 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Chamfering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.157 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: 5566931\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51735089447218,"sku":"5566931","price":230.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bda564c6a316eed3f4a51bc7b8ebf33.jpg?v=1788769804","url":"https:\/\/voomisupply.com\/products\/iscar-5566931-turning-insert-3-8-inch-diamond-isoturn","provider":"Voomi Supply","version":"1.0","type":"link"}
