Iscar 5509927 Turning Insert WNMX453M4MW IC6025 Carbide

Product Description

The ISCAR 5509927 is a WNMX453M4MW grade IC6025 solid carbide turning insert designed for metal-cutting lathe operations. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability at the cutting edge. The insert measures 8.70 mm (0.3425 inches) in length with a 1/2-inch inscribed circle and a 3/64-inch (0.0469 inches) corner radius. The 80-degree trigon shape with a positive rake geometry and M4M chip breaker makes this insert well suited for controlled chip evacuation during medium to finishing cuts. It is part of the ISCAR Heliturn series and is held by clamp or pin mounting methods.

This insert is intended for turning operations on stainless steel workpieces, corresponding to ISO material group M. It fits into the Heliturn series toolholders that accept WNMX-style inserts with a W-shape code, N clearance code, and M tolerance code. Typical applications include external and internal turning on CNC lathes in job shops, production machining environments, and maintenance shops handling stainless components. The wiper edge geometry supports improved surface finish at standard feed rates without requiring a feed rate reduction. Maximum depth of cut is 5.00 mm (0.197 inches).

Key Features

• IC6025 solid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for extended tool life on stainless steel
• 80-degree trigon (W) insert shape with positive rake for reduced cutting forces
• M4M chip breaker geometry for controlled chip formation during medium and finishing passes
• Wiper edge included for improved surface finish at standard feed rates
• Compatible with clamp and pin holding methods for secure insert retention
• ISO 13399 compliant for standardized tool data integration

Compatibility

Designed for use in Heliturn series toolholders accepting WNMX-style inserts with N clearance code, M tolerance code, and 453 insert size code. Optimized for primary workpiece material code M (stainless steel) per ISO classification.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and all power isolated before changing inserts. Use the appropriate torx or hex key to secure the clamp or pin per the toolholder manufacturer's torque specification. Inspect the toolholder seat and pocket for chips or debris before seating the new insert to ensure proper contact and runout.
