Iscar 6403917 Boring Bar 0.2362 in Right Hand Solid Carbide

Product Description

The ISCAR 6403917 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and turning centers. It features a right-hand cutting direction and a minimum bore diameter of 0.2362 inches (6.00 mm), making it suited for tight, small-diameter bores where rigidity and dimensional accuracy are critical. The bar carries a dual-layer TiAlN and TiN finish coating for heat resistance and extended tool life. Manufactured to ISCAR grade IC1008, it measures 1.378 inches overall length with a 6.00 mm shank diameter. Machinists and CNC operators working in precision shops install this tool in standard toolholding systems.

This boring bar is used in small-bore internal turning applications across precision machining, toolroom, and production environments. With a maximum bore depth of 0.2362 inches (6.00 mm), it is optimized for shallow, tight-tolerance bores in ferrous and non-ferrous materials. Its compact geometry makes it a practical choice for job shops and production cells where fine bore finishing or sizing cuts are required on turned components.

Key Features

• Minimum bore diameter of 0.2362 inches (6.00 mm) for small-bore internal turning
• Maximum bore depth of 0.2362 inches (6.00 mm)
• Solid carbide construction for rigidity and vibration resistance in tight bores
• Dual-layer TiAlN and TiN coating for thermal protection and wear resistance
• ISCAR manufacturer grade IC1008 for consistent cutting performance
• Right-hand cutting direction for standard CNC lathe setups

Compatibility

Designed as an OEM-style solid carbide boring bar for use in CNC lathes and turning centers accepting a 6.00 mm shank diameter toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before securing the boring bar in the toolholder. Ensure the shank is fully seated and clamped to the toolholder manufacturer's recommended torque specification. Verify bore alignment and runout before initiating a cut.
