Iscar 5595961 Boring Insert DCGT3-1AS IC907 Solid Carbide

Product Description

The ISCAR 5595961 is a solid carbide boring insert in the DCGT3-1AS style with an IC907 manufacturer grade. It is designed for precision internal and external turning operations on CNC and manual lathes. The insert features a 55-degree diamond shape with a positive rake geometry and an AS chipbreaker, which helps control chip flow and reduce cutting forces. The PVD-applied TiAlN and TiN dual coating delivers heat resistance and extended tool life across a wide range of workpiece materials. With a 1/64-inch corner radius and a 7-degree relief angle, this insert suits finishing and semi-finishing cuts where tight tolerances are required. Licensed machinists and CNC operators working in job shop or production environments are the primary installers.

This insert is part of the ISCAR Isoturn series and is rated for universal primary workpiece material application, covering material codes H, K, M, N, P, and S. That range includes hardened steels, cast iron, stainless steels, non-ferrous materials, carbon and alloy steels, and heat-resistant superalloys. It is suited for boring bars and turning tool holders that accept DCGT-style inserts with a 3/8-inch inscribed circle. Typical applications include internal diameter finishing, contour turning, and light interrupted cuts in production machining environments.

Key Features

• 55-degree diamond insert shape with positive rake for reduced cutting forces
• AS chipbreaker geometry supports efficient chip evacuation during boring and finishing operations
• 7-degree relief angle suits close-tolerance finishing and semi-finishing passes
• Universal material compatibility covering ISO codes H, K, M, N, P, and S
• Conforms to ISO 13399 standard for tooling data representation

Compatibility

Designed for use in DCGT-style boring bars and turning tool holders accepting a 3/8-inch inscribed circle insert. Compatible with workpiece materials across ISO codes H, K, M, N, P, and S as specified by ISCAR for the IC907 grade Isoturn series.

Installation Notes

Installation is performed by a licensed machinist or CNC tooling technician. Ensure the machine spindle is powered down and the tool holder is fully secured in the turret before seating or indexing the insert. Use the appropriate torx or hex key to torque the clamping screw per the tool holder manufacturer specification - do not overtighten, as carbide inserts are brittle and can crack under excessive clamp load. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper seating and accurate tool geometry.
