Iscar 6403805 Solid Carbide Boring Bar 0.1102 in Right Hand

Product Description

The ISCAR 6403805 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and turning centers. Built to a 4 mm shank diameter with a 30 mm overall length, it handles a minimum bore diameter of 0.1102 inches (2.80 mm) and a maximum bore depth of 0.5906 inches (15.00 mm). The bar carries a TiAlN finish coating and is manufactured to the IC908 grade, a carbide substrate suited for a range of ferrous and non-ferrous workpiece materials. It is a right-hand cut tool intended for machinists and toolroom professionals who need consistent, repeatable performance in small-diameter internal turning applications.

This boring bar is well suited to precision small-bore work in production and job-shop environments. Its compact geometry makes it a practical choice when machining tight-tolerance bores in components such as hydraulic fittings, medical parts, instrumentation housings, or any application where bore diameter starts below 3 mm. The TiAlN coating provides heat resistance at elevated cutting speeds. The solid carbide construction delivers rigidity in proportion to the bar diameter, reducing chatter in shallow-to-moderate depth passes up to 0.5906 inches deep.

Key Features

• Solid carbide construction for maximum rigidity at small shank diameters
• TiAlN finish coating for thermal resistance and extended tool life
• IC908 manufacturer grade for broad workpiece material compatibility
• Right-hand cut configuration for standard OD-turning-center setups
• Minimum bore diameter of 0.1102 inches (2.80 mm) for tight small-bore applications
• Maximum bore depth of 0.5906 inches (15.00 mm)

Compatibility

Designed as an OEM-style solid carbide boring bar for use in toolholding systems and turrets that accept a 4 mm round shank, on CNC turning centers and manual lathes equipped for small-diameter internal boring.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank fully within the toolholder to the manufacturer-specified minimum clamping length before engaging the workpiece. Power down and lock out the machine spindle before changing or adjusting tooling. Verify bore alignment and runout with a dial indicator before initiating a cutting pass to protect both the tool and the workpiece.
