Iscar 5540030 Ccgt Turning Insert 80 Degree Diamond

Product Description

The ISCAR 5540030 is a solid carbide turning insert in the CCGT style, designed for single-point turning operations on CNC and manual lathes. It features an 80-degree diamond shape with a positive rake geometry, a 0.3752-inch inscribed circle, and a 0.0039-inch corner radius. The insert carries ISCAR grade IC20 and is supplied uncoated, making it suited for finishing and semi-finishing cuts where coating is not required. The screw-clamped holding method and clearance code C geometry provide secure seating in compatible toolholders. Licensed machinists and CNC operators install this type of insert in production and job-shop turning applications.

This insert belongs to the ISCAR Isoturn series and is classified for universal primary workpiece material compatibility, covering material codes H, K, M, N, and S. It is appropriate for residential and commercial machine shops handling a broad range of metals and non-metals. The AS chip breaker geometry controls chip flow during light-to-moderate depth cuts, with a maximum depth of cut of 0.0984 inch (2.50 mm). The insert meets ISO 13399 standards and carries material grade designations C1, C2, C6, and C7.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque screwdriver or hex key specified for the toolholder to secure the clamping screw — do not overtighten or use impact tools on insert screws. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert.
