Iscar 6403832 Chamfering Boring Bar Solid Carbide

Product Description

The ISCAR 6403832 is a solid carbide chamfering boring bar designed for internal chamfering and bore finishing operations on CNC lathes and machining centers. It features a right-hand cutting direction and a minimum bore diameter of 0.2362 inches (6.00 mm), with a maximum bore depth of 0.9449 inches (24.00 mm). The bar carries a TiAlN finish coating and is manufactured to ISCAR grade IC908, a carbide grade suited for demanding cutting conditions in steel, stainless, and hardened materials. Overall length is 1.5748 inches (40.00 mm). The 0.0059-inch corner radius supports clean chamfer geometry at small bore entries. This tool is installed by machinists and CNC setup technicians working in precision turning or boring applications.

The 6403832 is intended for small-bore internal chamfering work where access is restricted and dimensional accuracy is critical. Its compact shank diameter of 6.00 mm allows entry into tight bores typical of precision components in aerospace, medical, and general manufacturing. The solid carbide construction provides the rigidity needed to maintain position and finish quality at depth-to-diameter ratios common in these applications. Right-hand cut orientation suits standard spindle rotation in the majority of CNC turning setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiAlN coating extends tool life in high-temperature cutting environments
• IC908 carbide grade rated for steel, stainless, and hardened workpiece materials
• 0.2362-inch (6.00 mm) minimum bore diameter supports small-bore entry
• 0.0059-inch corner radius for precise chamfer geometry
• Right-hand cut direction compatible with standard CNC lathe spindle rotation

Compatibility

Designed as an OEM-style solid carbide chamfering boring bar suitable for CNC lathes and machining centers equipped with tool holders accepting a 6.00 mm shank diameter.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician with the machine powered down and all axes at a safe home position before tool changes. Secure the shank fully within the tool holder to the manufacturer-specified clamping depth to minimize overhang and vibration. Verify cutting direction and spindle rotation match before initiating a cut cycle. Do not exceed the maximum bore depth of 0.9449 inches to prevent tool deflection or breakage.
