It carries the IC8250 manufacturer grade with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 55-degree diamond shape, a positive rake geometry, and an SM chip breaker configuration. Insert length is 11.6 mm (0.4567 inches), the inscribed circle measures 3\/8 inches (0.3748 inches), and the corner radius is 1\/32 inches (0.0315 inches). It is held by screw clamping and belongs to the ISCAR Isoturn series.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for turning stainless steel and carbon or alloy steel workpieces, covering ISO material groups M and P. It is suited for medium-finish to semi-roughing passes with a maximum depth of cut of 3.00 mm (0.1181 inches). Typical installations include external turning toolholders configured for DCMT insert geometry in shop environments ranging from production turning cells to job shop lathes. The SM chip breaker promotes reliable chip control when cutting ductile materials such as austenitic stainless steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC8250 grade with CVD TiCN, Al2O3, and TiN multilayer coating for extended tool life in steel and stainless applications\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (D) with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eSM chip breaker geometry optimized for stainless steel and steel chip control\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 3.00 mm (0.1181 inches) for medium to semi-rough passes\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 for use in DCMT-style screw-clamp turning toolholders within the ISCAR Isoturn series.

Use the appropriate Torx or hex key to seat and torque the clamping screw; refer to the toolholder manufacturer specification for the correct fastener torque value. Inspect the insert pocket and screw threads for debris or damage before seating a new insert. Do not exceed the maximum depth of cut rating for this insert geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\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: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: SM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\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 (0.3748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.60 mm (0.4567 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: 3.00 mm (0.1181 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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\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: 0.003 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: 5508103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728747036978,"sku":"5508103","price":282.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08904926ab2f6084c7c26c04a4a80b21.jpg?v=1788695766","url":"https:\/\/voomisupply.com\/products\/iscar-5508103-turning-insert-55-diamond-ic8250-isoturn","provider":"Voomi Supply","version":"1.0","type":"link"}
