Iscar 6404196 Profile Boring Bar Submicron Solid Carbide

Product Description

The ISCAR 6404196 is a solid carbide profile boring bar engineered for small-diameter internal profiling operations on CNC lathes and turning centers. Built from submicron-grade carbide with a TiAlN coating and IC908 manufacturer grade designation, this bar delivers wear resistance and thermal stability in demanding cutting conditions. It features a right-hand cutting direction, a minimum bore diameter of 0.1575 inches (4.00 mm), a maximum bore depth of 0.7874 inches (20.00 mm), and a corner radius of 0.008 inches. The 20-degree bar end angle supports precise profile geometry in tight bores. Licensed machinists and CNC tooling technicians are the primary installers of this tooling.

This profile boring bar is suited for small-bore internal turning and profiling in both production and job-shop environments. Its 4.00 mm shank diameter and 1.3386-inch overall length make it appropriate for applications where access to shallow, narrow bore profiles is required. Typical use cases include precision internal contour work on steel, stainless, and other materials where the TiAlN-plus-titanium nitride finish provides an advantage in tool life and surface finish quality.

Key Features

• Submicron solid carbide construction for rigidity and edge retention in small-bore profiling
• IC908 manufacturer grade with TiAlN and titanium nitride finish coating for thermal and wear resistance
• Right-hand cutting direction with 20-degree bar end angle for profile access
• Minimum bore diameter of 0.1575 inches (4.00 mm) for tight internal geometries
• Corner radius of 0.008 inches for controlled profile blending
• Maximum bore depth of 0.7874 inches (20.00 mm) with compact 1.3386-inch overall length

Compatibility

Designed as an OEM-style replacement and direct-use solid carbide profile boring bar for small-bore internal turning applications on CNC lathes and turning centers accepting a 4.00 mm shank diameter.

Installation Notes

Installation of boring bars should be performed by qualified machinists or CNC tooling technicians. Secure the shank fully in the tool holder to the manufacturer-recommended overhang length to minimize deflection and chatter. Power down and lock out the machine spindle before changing or setting tooling. Verify bore diameter and depth clearances against workpiece drawings before initiating the cutting cycle.
