Iscar 5504979 WBGT520L IC907 Carbide Turning Insert

Product Description

The ISCAR 5504979 is a solid carbide trigon turning insert in the WBGT520L geometry, designed for precision external turning operations on CNC lathes and turning centers. It carries the IC907 manufacturer grade with a PVD-applied TiAlN and TiN multilayer coating, which provides wear resistance and thermal stability across a broad range of workpiece materials. The insert is left-hand oriented, features an 80-degree included angle, and has a 0.0079-inch corner radius for controlled surface finish. Maximum depth of cut is 1.00 mm (0.0394 inches). The L chipbreaker geometry suits light-to-medium finishing passes. Installation requires a screw-clamping toolholder compatible with the WBGT insert style.

This insert is suited for use in production turning environments where consistent tool life and repeatable surface finish are required. The IC907 grade with PVD coating performs across universal workpiece material categories, making it applicable to steel, stainless, cast iron, non-ferrous, and high-temperature alloy turning operations as indicated by material codes H, K, M, N, P, and S under the ISO classification system. It is a single-insert package sold with a minimum order quantity of 10 units. Machinists and CNC tool crib technicians working in job shop or production settings are the primary users.

Compatibility

Designed for use in screw-clamp WBGT-style turning toolholders compatible with the Isoturn series. Suitable for workpiece materials classified under ISO codes H, K, M, N, P, and S, covering hardened materials, cast iron, stainless steel, non-ferrous metals, steel, and superalloys. No specific toolholder model numbers were provided in the product data.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Before changing inserts, the machine must be powered down and the spindle fully stopped in accordance with the machine tool manufacturer lockout procedures. Use the correct Torx or hex key specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the insert or damage the pocket. Inspect the toolholder pocket and shim for damage or debris before seating the new insert.
