Iscar 6403584 Boring Chamfering Profiling Bar Solid Carbide

Product Description

The ISCAR 6403584 is a solid carbide boring, chamfering, and profiling bar designed for precision internal machining operations. With a minimum bore diameter of 0.60 mm (0.0236 inches) and a maximum bore depth of 0.0790 inches, this bar handles extremely tight-tolerance small-bore work where rigidity and edge integrity are critical. The 4.00 mm shank diameter and 20.00 mm overall length (0.7874 inches) make it suited for CNC turning centers and Swiss-style lathes. Right-hand cutting direction. The solid carbide construction delivers superior rigidity and wear resistance compared to steel-bodied alternatives, making it a reliable choice for production environments running tight tolerances on small-diameter features.

This boring bar is intended for use on CNC lathes, turn-mill centers, and Swiss-type screw machines performing internal boring, chamfering, and profiling on small-diameter workpieces. Typical applications include precision components in medical, aerospace, and instrumentation industries where bore diameters under 1 mm are common. The right-hand cutting orientation suits standard spindle rotation setups. Machinists and CNC programmers working with miniature or micro-bore features will find this bar appropriate for finishing passes and contour work inside tight bore envelopes. A corner radius of 0.0016 inches supports controlled surface finish at bore entry and profile transitions.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance in small-bore applications
• Minimum bore diameter of 0.60 mm (0.0236 inches) for micro-bore and miniature component work
• Multipurpose geometry supports boring, chamfering, and profiling in a single tool
• Right-hand cutting direction for standard CNC lathe and Swiss-type machine setups
• Corner radius of 0.0016 inches for controlled surface finish at profile transitions
• Compact 20.00 mm overall length optimized for short-reach, high-precision internal operations

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC lathes, turn-mill centers, and Swiss-type screw machines accepting a 4.00 mm shank diameter boring bar.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state before changing or adjusting tooling. The 4.00 mm shank must be properly clamped in a compatible tool holder or collet to the manufacturer-specified holding depth to prevent deflection or tool pullout during cutting. Verify cutting direction and tool offset registration in the machine controller before initiating any cutting cycle.
