Iscar 6402319 Chamfering Boring Bar Solid Carbide

Product Description

The ISCAR 6402319 is a solid carbide chamfering boring bar designed for internal chamfering and boring operations on CNC lathes and machining centers. Built from solid carbide with a TiCN and TiN finish coating, it delivers hardness and wear resistance suited to tight-tolerance work in small-bore applications. The bar accepts a minimum bore diameter of 0.1969 inches (5.00 mm) and reaches a maximum bore depth of 0.9449 inches (24.00 mm), making it appropriate for shallow internal chamfer work where rigidity and precision are critical. Manufacturer grade IC228 further defines the carbide substrate for this tool.

This chamfering boring bar is used in production and job-shop environments where small-diameter internal chamfering is required. It fits right-hand cutting setups on turning centers and CNC lathes handling small-bore components such as hydraulic fittings, precision bushings, and instrumentation parts. The 5.00 mm shank diameter and 1.5748-inch overall length make it a compact tool suitable for close-clearance toolholding systems. Machinists and CNC operators working in aerospace, medical device, and fluid power component manufacturing will find this bar useful for consistent chamfer geometry in high-repeatability applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore chamfering
• TiCN and TiN dual finish coating for enhanced tool life and reduced built-up edge
• Manufacturer grade IC228 carbide substrate optimized for the intended cutting range
• 0.0059-inch corner radius provides controlled edge geometry for consistent chamfer quality
• Right-hand cutting direction for standard CNC lathe and turning center setups
• Compact 1.5748-inch overall length suits close-clearance toolholding arrangements

Compatibility

Designed as an OEM-style replacement or direct-use chamfering boring bar for CNC turning centers and lathes accommodating a 5.00 mm shank diameter toolholder with right-hand cutting orientation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or removing the boring bar from the toolholder. Ensure the shank is properly clamped to the specified torque for the toolholding system in use per the toolholder manufacturer guidelines. Verify bore diameter clearance and depth stop settings before initiating any cutting cycle.
