It carries the IC6025 manufacturer grade, which is engineered for cutting stainless steel and other difficult-to-machine M-group materials. The insert measures 8.70 mm (0.3425 inches) in length with a 0.5000-inch inscribed circle and a 1\/32-inch (0.0313-inch) corner radius. The 80-degree trigon shape (W code) provides good strength at the cutting edge. This insert is installed by machinists and CNC lathe operators in production and job-shop turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external and internal turning of stainless steel workpieces in both roughing and finishing passes within its rated maximum depth of cut of 4.00 mm (0.1575 inches). The positive rake geometry and TF chip breaker work together to manage chip evacuation on gummy, work-hardening materials. It fits standard WNMG-style insert pockets and is held by clamp or pin clamping methods. Typical applications include shaft turning, facing, and profiling operations on CNC lathes and turning centers in both residential shop and industrial production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC6025 CVD-coated grade with TiCN, Al2O3, and TiN multilayer coating optimized for stainless steel (ISO M workpiece material code)\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry with TF chip breaker for controlled chip flow on tough, work-hardening alloys\u003c\/li\u003e\n\u003cli\u003e80-degree trigon insert shape (WNMG style) with 0N clearance and M tolerance for reliable pocket fit\u003c\/li\u003e\n\u003cli\u003e1\/32-inch (0.0313-inch) corner radius balances edge strength with surface finish quality\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 4.00 mm (0.1575 inches) suitable for medium to light roughing and semi-finishing\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert holding methods for secure seating at elevated cutting speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for WNMG432-style toolholders and boring bars that accept W-geometry, M-tolerance turning inserts with a 0.5000-inch inscribed circle and clamp or pin clamping.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTurning inserts are seated and changed by machinists following standard CNC lathe lockout and energy-isolation procedures before any tooling work. Ensure the insert pocket is clean and free of debris before seating to maintain proper tolerance alignment. Torque clamping screws only to toolholder manufacturer specifications — do not over-torque, as this can fracture the carbide body. Inspect the insert for edge wear or chipping at regular intervals per shop tool-life management practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (W)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 8.70 mm (0.3425 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\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: Clamp, Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M)\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: 0.165 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: 5509921\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730454053170,"sku":"5509921","price":260.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/768328436314aa59bd950d9ef5e87bb2.jpg?v=1788717729","url":"https:\/\/voomisupply.com\/products\/iscar-5509921-wnmg432tf-ic6025-turning-insert-isoturn","provider":"Voomi Supply","version":"1.0","type":"link"}
