Iscar 6403535 Profile Boring Bar Solid Carbide

Product Description

The ISCAR 6403535 is a solid carbide profile boring bar designed for internal turning and profiling operations on CNC lathes and turning centers. With a minimum bore diameter of 0.2362 inches (6.00 mm) and a maximum bore depth of 0.9449 inches (24.00 mm), this bar handles tight-bore profiling where rigidity and dimensional accuracy are critical. The TiCN finish coating improves wear resistance and tool life in ferrous and non-ferrous materials. The IC228 grade designation indicates a fine-grain carbide substrate suited for finishing and semi-finishing passes. This tool is installed by CNC machinists and toolroom technicians working in precision turning applications.

This profile boring bar is suited for small-diameter internal profiling in both production and job-shop environments. Its 0.0295-inch corner radius supports controlled blending on internal profiles and shoulders. The right-hand cutting direction is standard for conventional lathe spindle rotation. With an overall length of 1.5748 inches (40.00 mm) and a 6.00 mm shank diameter, it fits compact boring bar holders and quick-change tooling systems used on small-to-medium turning centers.

Key Features

• Solid carbide construction for maximum rigidity in small-bore applications
• TiCN finish coating for enhanced wear resistance and reduced built-up edge
• IC228 carbide grade optimized for finishing and semi-finishing cuts
• 0.0295-inch corner radius for internal profile and shoulder blending
• Right-hand cutting direction for standard spindle rotation
• Compact 1.5748-inch overall length suited for tight tooling clearances

Compatibility

Designed as a direct-fit replacement or tooling addition for boring bar holders accepting a 6.00 mm round shank, compatible with small-bore internal turning and profiling setups on CNC and manual lathes.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Before mounting or changing tooling, ensure the machine spindle is fully stopped and the control is in a safe state. Verify shank clamping force against the toolholder manufacturer specifications and confirm bore clearance before engaging the cut. Inspect the cutting edge for chipping or coating wear before each use.
