Iscar 6403831 Solid Carbide Boring Bar Right Hand Cut

Product Description

The ISCAR 6403831 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and turning centers. It features a 6 mm shank diameter and an overall length of 37 mm (approximately 1.457 inches), making it suited for tight-bore applications requiring precise, consistent stock removal. The bar carries a TiAlN finish coating and is manufactured to the IC908 grade, a PVD-coated carbide grade optimized for steel, stainless, and hardened materials at moderate to high cutting speeds. Setup is right-hand cut orientation. This tool is installed and used by machinists and toolroom technicians working in precision metal cutting environments.

This boring bar is used in applications where minimum bore diameter access is critical. With a minimum bore diameter of 0.2362 inches (6.00 mm) and a maximum bore depth of 0.8268 inches (21.00 mm), it fits shallow internal bores in small-diameter workpieces. Typical applications include small component machining in aerospace, medical device, and general precision manufacturing. It is suited for use in gang tooling, Swiss-style turning, and conventional CNC lathe turrets where shank size and rigidity are tightly controlled.

Key Features

• Solid carbide construction for high rigidity and vibration resistance in small-bore applications
• TiAlN finish coating improves wear resistance and performance in dry or semi-dry cutting conditions
• IC908 manufacturer grade rated for steel, stainless, and hardened material applications
• Right-hand cut orientation for standard lathe and turning center setups
• 6 mm shank diameter fits standard small-bore toolholders and gang tool blocks
• Compact 37 mm overall length suits Swiss-style and sub-spindle turning applications

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for turning centers and CNC lathes accepting a 6 mm shank boring tool in right-hand cut orientation.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the spindle drive before seating or removing the bar from the toolholder. Verify shank clamp torque per the toolholder manufacturer specification and confirm tool overhang does not exceed recommended depth-to-diameter ratios for the holder in use. Do not exceed the cutting parameters specified in the ISCAR grade application data for IC908.
