Iscar 5594967 Dcgt Turning Insert 0.25 in Ic Solid Carbide

Product Description

The ISCAR 5594967 is a DCGT-style solid carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. It carries the IC520 manufacturer grade with a PVD-applied TiCN and TiN multilayer coating for wear resistance and edge stability at elevated cutting speeds. The insert measures 0.3051 inches in length with a 0.25 inch inscribed circle, a 0.0938 inch thickness, and a 0.0079 inch corner radius. The AS chip breaker geometry and positive rake angle promote free-cutting action. This insert is installed by machinists and CNC operators across job shop, aerospace, and general metalworking environments.

The 5594967 belongs to ISCAR's Isoturn series and is suited for universal workpiece materials with ISO material codes M, N, and S, covering stainless steels, non-ferrous materials, and heat-resistant superalloys. The screw-holding method provides secure clamping in compatible toolholders. Maximum depth of cut is 0.0787 inches (2.00 mm), making this insert appropriate for light to moderate finish and semi-finish turning passes where consistent surface finish and dimensional accuracy are required.

Key Features

• DCGT insert style with 55-degree diamond shape and positive rake geometry for low cutting forces
• IC520 grade with PVD TiCN and TiN coating for edge wear resistance
• AS chip breaker designed for reliable chip control across universal workpiece materials
• 0.0079 inch corner radius suitable for finish and semi-finish turning with tight tolerance requirements
• Screw-holding method (clearance code C, tolerance code G) for repeatable insert indexing
• Compliant with ISO 13399 cutting tool data representation standards

Compatibility

Designed for use in DCGT-compatible screw-clamp turning toolholders within the ISCAR Isoturn series. The insert size code is 2-0 and the 0.1102 inch hole diameter governs toolholder pin and screw fitment. Verify toolholder compatibility against the ISCAR Isoturn toolholder catalog using the DCGT insert style and size code before installation.

Installation Notes

Turning insert replacement is performed by qualified machinists or CNC setup technicians. Before indexing or replacing an insert, ensure the machine spindle is fully stopped, the program is held, and the turret or tool post is in a safe position. Use the correct torque screwdriver specified by the toolholder manufacturer to secure the clamping screw — do not over-torque, as this can fracture the insert or damage the seating pocket. Inspect the insert pocket and locating pin for wear or debris before seating a new insert.
