Iscar 6491465 Boring Bar 0.11 in Min Bore Solid Carbide

Product Description

The ISCAR 6491465 is a submicron solid carbide boring bar designed for internal turning and small-bore machining operations. It features a right-hand cutting direction and carries a dual TiAlN and TiN finish coating applied over an IC908 carbide grade substrate. With a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.354 inches, this bar is suited for tight-tolerance finish boring in small diameters. The overall length is 0.9449 inches with a 4.00 mm shank diameter and a corner radius of 0.004 inches. Machinists and CNC operators working with small-bore components will find this bar well matched to precision internal profiling applications.

This boring bar is intended for use in small-diameter internal machining applications on CNC lathes and machining centers. The 4.00 mm shank diameter suits tool holders and spindle interfaces configured for metric shank tooling. The IC908 manufacturer grade and submicron carbide material make this bar appropriate for finishing passes in ferrous and non-ferrous workpiece materials where close tolerances and smooth surface finishes are required. It is a single-piece solid carbide construction with no inserts to index.

Key Features

• Minimum bore diameter of 0.11 inches for small-bore internal turning
• Maximum bore depth of 0.354 inches supports shallow to moderate internal reach
• Submicron solid carbide construction with IC908 manufacturer grade for wear resistance
• Dual TiAlN and TiN finish coating for heat and abrasion resistance
• 0.004 inches corner radius for controlled surface finish on internal profiles
• Right-hand cutting direction for standard CNC lathe setups

Compatibility

Designed as an OEM-style solid carbide boring bar compatible with tool holders accepting a 4.00 mm round shank for small-bore internal turning operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar from the tool holder. Confirm the shank is properly clamped to the specified holder bore and that overhang is minimized to reduce deflection during cutting. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running initial test passes.
