Micro 100 BB-160750 Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-160750 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. It cuts right-hand and accepts a minimum bore diameter of 0.16 inches with a maximum bore depth of 0.75 inches. The 3/16-inch shank diameter and 2-inch overall length make this a compact tool suited for small-bore finish and semi-finish work. A 0.006-inch corner radius produces a clean shoulder and reduces chatter in tight bore profiles. Machinists and tool-and-die professionals install this bar where high rigidity and dimensional accuracy are critical.

This boring bar is used in small-bore internal turning applications in job shops, production machining cells, and precision manufacturing environments. It is well suited for ferrous and non-ferrous materials where a rigid, uncoated solid carbide tool body provides the stiffness needed to hold tight tolerances at depth. The compact geometry makes it appropriate for parts with restricted bore entry or shallow counterbore features.

Key Features

• Solid carbide construction provides high rigidity and resistance to deflection in small-bore applications
• Minimum bore diameter of 0.16 inches suits tight, restricted-entry bore work
• Maximum bore depth of 0.75 inches supports a range of shallow to moderate depth internal features
• Right-hand cutting direction compatible with standard lathe spindle rotation
• 0.006-inch corner radius delivers clean shoulder transitions and reduced stress concentration
• Uncoated finish allows direct inspection of tool wear and suits a wide range of workpiece materials

Compatibility

Designed as a direct-fit solid carbide boring bar for tool holders and boring bar blocks accepting a 3/16-inch round shank diameter in CNC and manual turning applications.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the tool holder bore and verify overhang does not exceed the maximum bore depth before engaging the cut. Ensure the machine spindle is fully stopped and the control is in an e-stop or safe state before installing or removing the bar. Avoid side-loading the bar beyond its rated bore depth, as solid carbide is brittle and susceptible to fracture under impact or excessive cantilever.
