Iscar 6403525 Profile Boring Bar Solid Carbide

Product Description

The ISCAR 6403525 is a solid carbide profile boring bar designed for internal profiling operations on CNC lathes and turning centers. It cuts in a right-hand direction and is built for small-bore work, with a minimum bore diameter of 0.1575 inches (4.00 mm) and a maximum bore depth of 0.5906 inches (15.00 mm). The overall length is 1.1811 inches (30.00 mm), and the corner radius is 0.0197 inches, making it suited for tight-tolerance internal contour work. A TiCN and TiN finish coating improves wear resistance and extends tool life in ferrous and non-ferrous materials. Manufactured to ISCAR grade IC228, this bar delivers consistent performance in precision machining environments. Machinists and CNC operators working with small-diameter bores will find this bar appropriate for demanding finish and profile applications.

This profile boring bar is intended for internal boring and profiling operations requiring access to small-diameter features. It is commonly used in precision turned-part production, medical component machining, and toolroom work where tight bore tolerances and controlled surface finish are critical. The compact geometry and solid carbide construction make it appropriate for high-speed, low-vibration cutting in short-overhang setups on CNC turning equipment.

Key Features

• Solid carbide construction provides rigidity and dimensional stability in small-bore applications
• Right-hand cutting direction for standard lathe and turning center setups
• TiCN and TiN finish coating for improved wear resistance and reduced built-up edge
• Minimum bore diameter of 0.1575 inches suits precision small-bore profiling work
• Corner radius of 0.0197 inches enables tight internal contour transitions
• ISCAR grade IC228 for consistent performance in production turning environments

Compatibility

Designed as a solid carbide profile boring bar for use in CNC lathes and turning centers capable of accommodating a 4.00 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank firmly in a compatible boring bar holder or collet chuck, ensuring proper stick-out is minimized to reduce deflection. Verify spindle is fully stopped and machine is locked out before mounting or removing the tool. Follow the machine tool manufacturer's recommended clamping torque specifications for the toolholder in use.
