Iscar 5507754 Cnmg 432-TF IC8250 Turning Insert Solid Carbide

Product Description

The ISCAR 5507754 is a CNMG 432-TF turning insert in the Isoturn series, designed for general turning operations on CNC lathes and turning centers. Built from solid carbide and finished with a CVD-applied TiCN, Al2O3, and TiN multilayer coating, this insert delivers wear resistance and thermal stability across a range of cutting conditions. The 80-degree diamond (C-style) shape with a neutral 0-degree relief angle suits positive-rake toolholders. With a 0.5-inch inscribed circle and a 0.031-inch corner radius, it handles moderate to aggressive material removal. Machinists and tooling specialists install this insert in compatible CNMG-style clamp or pin-lock toolholders.

This insert is rated for primary use on stainless steel and steel workpieces, corresponding to ISO material codes M and P. It fits into typical turning center setups where consistent chip control is required across roughing and semi-finishing passes. The TF chip breaker geometry is suited to moderate feed rates and depths of cut up to 3.99 mm (0.157 inches). It is part of ISCAR's Isoturn product line, which targets general-purpose external and internal turning applications in production environments.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully in the pocket and secure with the appropriate clamp or pin to the toolholder manufacturer's specified procedure. Inspect the insert seat and shim for wear or debris before installing a new insert to avoid seating errors.
