Accupro B160400A Boring Bar Submicron Carbide Altin

Product Description

The ACCUPRO B160400A is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and turning centers. Built from submicron-grade carbide and finished with an AlTiN (aluminum titanium nitride) coating, it delivers extended tool life and thermal resistance in demanding cutting conditions. The bar handles a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.4 inches. With a 3/16-inch shank diameter and an overall length of 2 inches, it fits compact tooling setups where rigidity and reach must be balanced. Right-hand cut geometry makes it suitable for standard turning configurations.

This boring bar is intended for use in precision machining environments where tight bore tolerances are required. Typical applications include finishing and semi-finishing of small-diameter bores in ferrous and non-ferrous materials. The AlTiN coating provides elevated hardness and oxidation resistance, making it well suited for dry or minimal-lubrication cutting strategies in production and job-shop settings. Machinists and CNC operators working with small-bore components will find the combination of submicron carbide substrate and AlTiN coating effective for maintaining dimensional consistency across high-cycle runs.

Key Features

• Submicron solid carbide substrate for superior wear resistance and edge stability
• AlTiN coating provides thermal hardness and oxidation resistance at elevated cutting temperatures
• Minimum bore diameter of 0.16 inches for precision small-bore applications
• Maximum bore depth of 0.4 inches
• Right-hand cut geometry for standard turning setups
• Compact 3/16-inch shank diameter and 2-inch overall length for tight tooling clearances

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC lathes and turning centers accepting a 3/16-inch shank boring bar with right-hand cut orientation.

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 tooling. Secure the shank firmly in the tool holder to the specified clamping requirements of your tooling system to prevent chatter and maintain bore accuracy. Verify bore diameter and depth settings against part specifications before beginning a production run.
