Iscar 6402763 Boring Bar 0.315 in Min Bore Solid Carbide

Product Description

The ISCAR 6402763 is a solid carbide boring bar designed for internal diameter machining in metal cutting applications. It delivers a minimum bore diameter of 0.315 inches (8.00 mm) with a maximum bore depth of 0.0984 inches (2.50 mm) and an overall length of 1.0236 inches (26.00 mm). The bar features a TiCN and TiN finish coating applied over the solid carbide substrate, and is manufactured to ISCAR grade IC228. It is designed for right-hand cutting direction. This tool is installed and used by machinists and CNC operators performing precision internal boring operations.

This boring bar is suited for small-diameter internal boring applications where tight tolerances and rigidity are required. The solid carbide construction makes it appropriate for use in CNC lathes and machining centers handling materials that demand a hard, wear-resistant cutting tool. The compact overall length and 6.00 mm shank diameter make it well-suited for short-reach, small-bore work in production and job shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding bore applications
• Minimum bore diameter of 0.315 inches (8.00 mm) supports small internal diameter work
• TiCN and TiN dual-layer coating improves surface hardness and tool life
• ISCAR manufacturer grade IC228 for consistent cutting performance
• Right-hand cutting direction for standard lathe and machining center setups
• Overall length of 1.0236 inches (26.00 mm) with 6.00 mm shank diameter for compact fitment

Compatibility

Designed as an OEM-style solid carbide boring bar for use in CNC lathes and machining centers requiring a right-hand, small-diameter internal boring tool with a 6.00 mm shank diameter.

Installation Notes

This boring bar is installed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing or setting tooling. Verify shank diameter compatibility with the toolholder before installation, and confirm boring bar projection and overhang meet the requirements of the specific operation. Follow the machine manufacturer guidelines and applicable shop safety procedures during setup.
