Micro 100 BB-160400 Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-160400 is a solid carbide boring bar designed for internal diameter machining in precision turning and boring operations. With a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.4 inches, this bar handles tight-tolerance small-bore work where rigidity and wear resistance are critical. The right-hand cutting direction suits standard lathe and boring mill setups. A 0.006-inch corner radius provides clean finishes on bore walls. Machinists and toolroom professionals working on CNC lathes, manual lathes, or mill-turn centers will find this bar suited to production and prototype work requiring consistent, repeatable bore geometry.

This boring bar is intended for small-bore internal turning applications in both production and job-shop environments. The 3/16-inch shank diameter fits standard boring bar holders and quick-change tooling systems commonly used on compact CNC lathes and toolroom lathes. The 2-inch overall length keeps overhang manageable, supporting chatter-free cuts in shallow to moderate-depth bores. Solid carbide construction makes this bar appropriate for harder workpiece materials including alloy steels, stainless steels, cast iron, and hardened materials where high-speed steel tooling would be inadequate.

Key Features

• Minimum bore diameter of 0.16 inches for tight small-bore applications
• Maximum bore depth of 0.4 inches
• Right-hand cutting direction for standard lathe orientation
• Solid carbide construction for rigidity and extended tool life
• 0.006-inch corner radius for controlled surface finish
• 3/16-inch shank diameter with 2-inch overall length for compact tooling setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for boring bar holders and quick-change tool systems accepting a 3/16-inch shank diameter on compatible CNC and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling and setup procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the boring bar. Secure the shank firmly in the boring bar holder to the minimum recommended engagement depth to reduce deflection and chatter. Follow applicable shop safety standards and machine manufacturer guidelines for cutting parameters.
