Iscar 6404206 Profile Boring Bar Submicron Solid Carbide

Product Description

The ISCAR 6404206 is a solid carbide profile boring bar designed for internal profiling and contour boring operations on CNC lathes and turning centers. Built from submicron-grade carbide (IC908) with a dual TiAlN and TiN coating, it delivers wear resistance and thermal stability in demanding cutting conditions. The right-hand cutting geometry suits standard spindle rotation setups. Key dimensional specs include a 0.2362-inch minimum bore diameter, 0.8661-inch maximum bore depth, 1.4567-inch overall length, and a 0.0080-inch corner radius. Installed by machinists and CNC operators, this bar is suited for precision small-bore work in production and job-shop environments.

This profile boring bar is intended for small-diameter internal profiling applications where bore access is tight and dimensional accuracy is critical. The 6-millimeter shank diameter and compact 37-millimeter overall length make it a practical choice for short-reach bores in ferrous and non-ferrous workpieces. The 20-degree bar end angle supports clearance in profiling cuts. It is typically used in high-volume turning operations where consistent surface finish and tool life are priorities.

Key Features

• Submicron solid carbide construction (IC908 grade) for extended tool life in hard and abrasive materials
• Dual TiAlN and TiN finish coating for heat resistance and reduced built-up edge
• 0.2362-inch minimum bore diameter enables access to tight internal profiles
• 0.0080-inch corner radius for controlled contour and profile accuracy
• 20-degree bar end angle provides clearance geometry for profiling passes
• Right-hand cut orientation compatible with standard CNC turning center spindle direction

Compatibility

Designed as an OEM-style solid carbide profile boring bar suitable for use in standard CNC lathe and turning center tooling systems accepting a 6-millimeter shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or removing the boring bar from its holder. Verify shank clamping torque per the toolholder manufacturer specifications and confirm bore clearance before starting the cut. Do not exceed the maximum bore depth of 0.8661 inches to avoid deflection or tool breakage.
