Iscar 5594887 Carbide Turning Insert 3/8 in Ic 55 Deg

Product Description

The ISCAR 5594887 is a DCGT-style carbide turning insert designed for precision finishing operations on a wide range of workpiece materials. Manufactured to ISO 13399 standards, this insert features a 55-degree diamond (rhombic) shape with a positive rake and positive side clearance geometry that reduces cutting forces and improves surface finish. The IC320 grade substrate carries a PVD-applied TiCN coating that delivers high wear resistance across stainless steel, cast iron, aluminum and non-ferrous metals, and special or super alloys. Secured by screw-type insert holding, the 5594887 is a reliable choice for machinists and tool-and-die shops running high-precision turning programs.

This insert is suited for light finishing cuts on CNC lathes and turning centers in both job-shop and production environments. The AS chip breaker geometry is optimized for finishing passes where tight tolerances and superior surface finish are required. Compatible workpiece material categories span universal applications including P (steel), M (stainless steel), K (cast iron), N (aluminum and non-ferrous), and S (special and super alloys), making it a versatile option across multiple machining programs.

Key Features

• AS chip breaker optimized for finishing operations
• Screw-type insert holding method for secure, repeatable clamping
• Meets ISO 13399 standards for tooling data representation
• Maximum depth of cut of 2.50 mm (0.0984 inches) for controlled finishing passes

Compatibility

Designed as an OEM-style replacement or direct-fit insert for DCGT-style turning toolholders with a ANSI size code 3-1 and ISO size code 11T304 seat configuration. Compatible across P, M, K, N, and S workpiece material categories per ISO classification.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert seat is clean and free of chips before seating the new insert. Follow the toolholder manufacturer's clamping procedure to avoid insert fracture or improper seating.
