Iscar 6403555 Profile Boring Bar Solid Carbide

Product Description

The ISCAR 6403555 is a solid carbide profile boring bar designed for internal profiling operations on CNC lathes and turning centers. It handles a minimum bore diameter of 0.1969 inches (5.00 mm) and a maximum bore depth of 0.5512 inches (14.00 mm), making it well suited for small-diameter internal features. The bar has an overall length of 1.1811 inches (30.00 mm) and a 0.0059-inch corner radius. A TiAlN finish coating improves heat resistance and extends tool life in demanding cutting conditions. ISCAR grade IC908 is the specified manufacturer grade for this bar. Right-hand cutting direction is standard. Machinists and CNC tooling specialists are the primary users.

This profile boring bar is used in precision small-bore internal turning applications where tight dimensional control is required. It fits into applications calling for a 5.00 mm shank diameter, typical in Swiss-type lathes, gang-tool setups, and compact turning centers. It is appropriate for profiling grooves, contours, and stepped bores in metalworking environments where solid carbide rigidity is needed to minimize deflection in shallow, small-diameter bores.

Key Features

• Solid carbide construction for rigidity and minimal deflection in small-bore applications
• TiAlN coating for improved heat resistance and extended tool life
• Minimum bore diameter of 0.1969 inches (5.00 mm)
• Maximum bore depth of 0.5512 inches (14.00 mm)
• 0.0059-inch corner radius for precise internal profile geometry
• ISCAR manufacturer grade IC908 for consistent performance in demanding cuts

Compatibility

Designed for use in CNC lathes and turning centers accepting a 5.00 mm shank diameter boring bar. Consult machine tooling specifications to confirm bore bar shank fitment before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and in a locked-out state before mounting or changing tooling. Secure the bar in the appropriate bore bar holder or tool block to the holding system manufacturer specifications, and verify shank seating before resuming operations. Check runout after mounting to confirm alignment before taking a cut.
