Iscar 6402419 Boring Bar 0.2677 in Min Bore Solid Carbide

Product Description

The ISCAR 6402419 is a solid carbide boring bar designed for internal boring operations on CNC lathes and turning centers. It cuts in a right-hand direction and delivers a minimum bore diameter of 0.2677 inches (6.80 mm), making it well suited for small-bore finish and semi-finish work. The bar has an overall length of 1.5748 inches (40.00 mm) and a shank diameter of 7.00 mm. A TiCN and TiN finish coating improves wear resistance and helps maintain edge integrity during extended cuts. Manufactured to ISCAR grade IC228, this bar is intended for machinists and toolroom technicians working with tight bore tolerances on precision components.

This boring bar is used in production and job-shop environments where small-diameter internal bores are required. Its compact overall length and 0.945-inch maximum bore depth make it appropriate for shallow blind-bore applications on turned parts. It is installed in a compatible boring bar holder or cartridge system on CNC turning equipment. The right-hand cutting direction suits standard spindle rotation in the majority of lathe setups. This tool is typically selected for applications involving hardened steels, cast iron, and other materials where carbide grade IC228 and TiCN-TiN coating provide the needed cutting-edge performance.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore applications
• Minimum bore diameter of 0.2677 inches (6.80 mm) for tight internal features
• Maximum bore depth of 0.945 inches for shallow to moderate blind bores
• TiCN and TiN finish coating for extended tool life and reduced built-up edge
• ISCAR grade IC228 for consistent performance on a range of workpiece materials
• Right-hand cutting direction compatible with standard lathe spindle rotation

Compatibility

Designed for use in compatible ISCAR boring bar holders and cartridge systems that accept a 7.00 mm shank diameter. Verify holder bore diameter and clamping method before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before mounting or removing the boring bar from its holder. Ensure the shank is fully seated and clamped to the holder manufacturer's specified engagement depth to minimize overhang and chatter. Inspect the cutting edge for chips or coating damage before each use.
