Iscar 5507825 WNMG332TF IC8250 Turning Insert Carbide

Product Description

The ISCAR 5507825 is a WNMG332TF-grade indexable turning insert in the Isoturn series, designed for external turning and boring operations on CNC lathes and turning centers. It carries the IC8250 manufacturer grade with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability at the cutting edge. The insert measures 6.53 mm (0.257 inches) in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius. It is installed by licensed machinists and CNC operators working on production turning applications.

This insert is primarily applied to stainless steel and steel workpieces, covering ISO material codes M and P. The TF chip breaker geometry and positive rake angle make it well suited for medium finishing and semi-finishing passes. Its 80-degree trigon (W) shape with a neutral clearance angle (Code N) and M tolerance class provides consistent dimensional repeatability across indexing. The Isoturn series designation positions it for a range of general turning and boring operations in both job shop and production environments.

Key Features

• IC8250 grade with CVD multilayer TiCN, Al2O3, and TiN coating for extended tool life on steel and stainless
• 80-degree trigon (WNMG) insert shape with positive rake for reduced cutting forces
• 1/32-inch corner radius suitable for medium finishing and semi-finishing cuts
• TF chip breaker geometry promotes controlled chip evacuation on stainless and steel
• Maximum depth of cut of 3.00 mm (0.118 inches)
• Multi-use rated for both external turning and boring applications

Compatibility

Designed as an OEM-style replacement and direct-fit indexable insert for turning toolholders accepting WNMG 332 geometry inserts with clamp or pin insert-holding methods.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is locked before indexing or replacing the insert. Seat the insert fully against the toolholder pocket and verify the clamp or pin is torqued according to the toolholder manufacturer's specification. Inspect the insert pocket for chips or debris before seating to avoid insert rocking and premature edge failure.
