Iscar 6402325 Chamfering Boring Bar Solid Carbide

Product Description

The ISCAR 6402325 is a solid carbide chamfering boring bar designed for internal chamfering and contouring operations on small-diameter bores. With a minimum bore diameter of 0.2362 inches (6.00 mm) and a maximum bore depth of 0.0197 inches (0.50 mm), this bar handles tight-tolerance finish work in precision machining environments. The left-hand cutting direction suits specific spindle configurations and workholding setups. A TiCN and TiN finish coating improves wear resistance and surface finish. Manufactured to ISCAR grade IC228, this tool is suited for machinists and toolroom professionals running CNC lathes or boring mills where consistent chamfer geometry is required.

This chamfering boring bar is used in precision turning and boring applications where small internal features require a controlled chamfer or angular form. It is appropriate for both production and toolroom environments handling ferrous and non-ferrous materials. The 0.0059-inch corner radius contributes to clean edge definition at the chamfer transition. With an overall length of 1.4567 inches (37.00 mm) and a 6.00 mm shank diameter, it fits standard small-bore tool holders common in Swiss-type and CNC turning centers. Installation is performed by qualified machinists familiar with internal tooling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore applications
• TiCN and TiN dual finish coating for extended tool life and reduced friction
• Left-hand cutting direction for specific spindle and workholding configurations
• Minimum bore diameter of 0.2362 inches (6.00 mm) for tight-clearance chamfering
• Corner radius of 0.0059 inches for controlled chamfer geometry
• ISCAR grade IC228 for consistent performance in precision machining

Compatibility

Designed as an OEM-style replacement and standard tooling option for small-bore internal chamfering applications using tool holders with a 6.00 mm shank bore, common on CNC turning centers and Swiss-type lathes.

Installation Notes

Installation should be performed by a qualified machinist familiar with internal boring bar setups. Ensure the machine spindle is fully stopped and all power is off before changing tooling. Secure the shank firmly in a compatible tool holder to the holder manufacturer's specified clamping method, and verify runout before committing to a production cut. Do not exceed the maximum bore depth of 0.0197 inches per the tool geometry.
