It carries the IC8250 manufacturer grade and features a multi-layer PVD coating of TiCN, Al2O3, and TiN applied over the carbide substrate. The SM chip breaker geometry and positive rake angle support controlled chip formation during turning operations. With a 35-degree included angle, a 3\/8-inch inscribed circle, and a 1\/32-inch corner radius, this insert is suited for precision turning passes on steel and stainless steel workpieces. Licensed machinists and CNC lathe operators will find this insert relevant for finishing and semi-finishing applications where tight tolerances are required.\u003c\/p\u003e\u003cp\u003eThis insert is used in external turning operations on CNC lathes and manual turning centers. It is designed for primary workpiece materials coded M and P under ISO classification, corresponding to stainless steel and carbon or alloy steel. The Isoturn series designation indicates compatibility with ISCAR Isoturn toolholders that accept VCMT geometry inserts secured by screw clamping. A maximum depth of cut of 2.50 mm (0.0984 inches) is appropriate for finishing and light semi-finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC8250 grade with PVD-applied TiCN, Al2O3, and TiN multilayer coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eSM chip breaker for controlled chip evacuation during finishing passes\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces and heat generation at the insert edge\u003c\/li\u003e\n\u003cli\u003e35-degree diamond shape (VCMT) provides a sharp, accessible cutting edge for contour turning\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure seating in compatible Isoturn toolholders\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 for standardized tool data exchange\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ISCAR Isoturn series toolholders that accept VCMT-style screw-clamped inserts.

Use the appropriate Torx or hex key to secure the clamping screw; do not overtighten, as this can crack the carbide insert. Verify the insert pocket is clean and free of chips or debris before seating a new insert. Follow the toolholder manufacturer specifications for screw torque and insert orientation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 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 (PVD process)\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\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\/32 inch (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.60 mm (0.6535 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\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: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO M, P)\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: 0.23 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: 5508142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737138004274,"sku":"5508142","price":366.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4df68e82c1a2dcbac8a1ed054dbe4072.jpg?v=1788784824","url":"https:\/\/voomisupply.com\/products\/iscar-5508142-vcmt332sm-ic8250-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
