Iscar 6402695 Solid Carbide Boring Bar 0.315 in Min Bore

Product Description

The ISCAR 6402695 is a solid carbide boring bar designed for internal turning and bore finishing operations on CNC lathes and machining centers. It produces a right-hand cutting direction and is suited for small-diameter bore work, with a minimum bore diameter of 0.315 inches (8.00 mm) and a maximum bore depth of 0.1378 inches (3.50 mm). The bar carries a dual TiCN and TiN finish coating over an IC228 manufacturer grade carbide substrate, which supports wear resistance in both ferrous and non-ferrous applications. Overall length is 1.378 inches (35.00 mm). This tool is installed by machinists and tool-and-die professionals on production or job-shop turning equipment.

This boring bar is suited for tight-tolerance internal bore work in small-diameter applications, including finish boring, chamfering, and light profiling in confined bore geometries. The 7.00 mm shank diameter allows fitment in small-bore tool holders typically found on Swiss-type lathes, gang-tool lathes, and compact CNC turning centers. It is appropriate for both production runs and prototype work where consistent bore diameter and surface finish are required.

Key Features

• Solid carbide construction for rigidity and dimensional stability in small-bore applications
• Right-hand cutting direction for standard OD and ID turning setups
• Dual TiCN and TiN coating for improved wear life and heat resistance
• IC228 carbide grade optimized for a broad range of workpiece materials
• Minimum bore diameter of 0.315 inches (8.00 mm) for tight-clearance bore access
• Compact 1.378-inch overall length for use in close-clearance tool positions

Compatibility

Designed as a replacement-style solid carbide boring bar for small-bore internal turning applications requiring a 7.00 mm shank diameter and right-hand cut geometry.

Installation Notes

Installation is performed by qualified machinists following the machine tool manufacturer guidelines and applicable shop safety procedures. Power down and lock out the spindle before mounting or removing the boring bar. Ensure the tool holder bore and shank diameter are clean and within tolerance before seating the bar. Do not exceed the maximum bore depth specification, as overhang beyond the rated depth increases deflection and risk of tool breakage.
