Iscar 6402316 Solid Carbide Boring Bar Right Hand Cut

Product Description

The ISCAR 6402316 is a solid carbide boring bar designed for internal diameter machining operations requiring tight dimensional accuracy and fine surface finishes. With a minimum bore diameter of 0.1969 inches (5.00 mm) and a maximum bore depth of 0.5512 inches (14.00 mm), this tool handles small-bore applications where rigidity and precision are critical. The 5.00 mm shank diameter and 30.00 mm overall length make it well suited to compact workholding setups. A TiN finish coating helps reduce friction and extend tool life in production environments. The manufacturer grade is IC228, a carbide grade formulated for consistent performance in fine boring applications.

This boring bar is used in CNC turning centers, mill-turn machines, and manual lathes where small internal diameters must be held to close tolerances. Right-hand cutting direction means it is configured for standard forward-feed boring passes. Its compact overall length and small shank diameter make it appropriate for swiss-type and small-part machining applications. Machinists and toolroom technicians working on small mechanical components, hydraulic fittings, or instrument parts will find this bar a direct-fit tooling solution for sub-quarter-inch bore work.

Key Features

• Solid carbide construction provides rigidity and vibration resistance in small-bore conditions
• TiN finish coating reduces built-up edge and extends cutting life
• Minimum bore diameter of 0.1969 inches (5.00 mm) enables fine internal machining
• Maximum bore depth of 0.5512 inches (14.00 mm) accommodates typical small-part bore depths
• Right-hand cut configuration for standard forward-feed turning operations
• IC228 carbide grade suited for consistent performance in finish boring

Compatibility

Designed as an OEM-style solid carbide boring bar for use in toolholders and boring bar holders accepting a 5.00 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret or toolpost is de-energized before mounting or removing the boring bar. Confirm the toolholder bore and clamping screws are clean and free of chips before seating the shank. Follow the machine builder and tooling manufacturer guidelines for stick-out length to minimize deflection during cuts.
