Iscar 6403995 Boring Bar 0.2362 in Solid Carbide

Product Description

The ISCAR 6403995 is a solid carbide boring bar designed for internal turning and bore finishing operations on CNC lathes and machining centers. Built from submicron-grade carbide with a TiAlN and TiN finish coating and manufactured to the IC908 grade specification, this bar delivers the hardness and edge integrity needed for consistent, tight-tolerance work. It accepts a minimum bore diameter of 0.2362 inches (6.00 mm) and reaches a maximum bore depth of 1.1811 inches (30.00 mm). A 0.002 inch corner radius contributes to surface finish quality in precision bore applications. Right-hand cutting geometry suits standard lathe setup. Installed by CNC machinists and toolroom technicians.

This boring bar suits small-diameter internal bore operations in ferrous and non-ferrous materials where a compact, rigid tool is required. With a 6.00 mm shank diameter and 30.00 mm overall length, it fits modular boring systems and small-bore toolholders configured for Swiss-style, gang-tool, or turret-style lathes. The IC908 grade and dual-layer coating make it appropriate for semi-finish to finish passes where tool life and dimensional repeatability are priorities. It is sold individually and packaged as a single-unit item.

Key Features

• Submicron solid carbide construction for rigidity and edge retention in small-bore applications
• TiAlN and TiN dual-layer finish coating for extended tool life and heat resistance
• IC908 manufacturer grade suitable for semi-finish and finish boring passes
• 0.002 inch corner radius for controlled surface finish in precision bores
• Right-hand cutting direction for standard lathe orientation
• Compact geometry: 6.00 mm shank diameter and 30.00 mm overall length for small-bore toolholding systems

Compatibility

Designed as an OEM-style solid carbide boring bar for small-bore internal turning applications; compatible with toolholders accepting a 6.00 mm shank diameter in CNC lathe and machining center setups.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in a safe state before changing or indexing tooling. Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth to minimize overhang deflection. Verify bore geometry and depth limits against the workpiece drawing before commencing the cut.
