Iscar 5508239 SNMG432TF IC807 Turning Insert Carbide

Product Description

The ISCAR 5508239 is a SNMG-style solid carbide turning insert in the Isoturn series, designed for precision external and internal turning operations on CNC lathes and turning centers. Coated with TiAlN via a PVD process, the IC807 grade delivers wear resistance and thermal stability across a range of workpiece materials. The insert features a 0.5-inch inscribed circle, a 3/16-inch thickness, and a 1/32-inch corner radius, making it suitable for medium to semi-finishing cuts. It is installed by licensed machinists and CNC operators working with ferrous and non-ferrous alloys.

This insert is intended for machining primary workpiece material categories M, P, and S, corresponding to stainless steels, carbon and alloy steels, and superalloys. The TF chip breaker geometry promotes positive rake cutting action, supporting controlled chip formation during turning. Typical applications include shaft turning, facing, and profiling operations in production and job-shop environments. The clamp and pin holding method ensures secure seating in compatible SNMG toolholders.

• TF chip breaker for controlled chip evacuation during medium-to-finish turning
• 0.5-inch inscribed circle and 3/16-inch thickness for rigid, stable seating
• 1/32-inch corner radius balances edge strength and surface finish quality
• Clamp and pin holding method for secure insert retention in SNMG toolholders
• Conforms to ISO 13399 cutting tool data standards

Compatibility

Designed as an OEM-style replacement and standard production insert for SNMG-style toolholders accepting 432-size inserts with clamp and pin retention. Compatible with workpiece material ISO categories M, P, and S.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine powered down and the spindle fully stopped before index or replacement. Use a torx or hex key of the correct size as specified by the toolholder manufacturer to seat the clamp securely. Inspect the toolholder pocket and seating surfaces for debris or wear before inserting. Verify insert orientation matches the required chip breaker direction for the programmed toolpath before resuming cutting operations.
