Micro 100 QBB-2001000-000X Boring Bar Solid Carbide 1/4 in Shank

Product Description

The MICRO 100 QBB-2001000-000X is a solid carbide boring bar designed for precision internal diameter work on CNC lathes and manual turning centers. With a minimum bore diameter of 0.2000 inches and a maximum bore depth of 1 inch, this bar handles tight-tolerance small-bore operations where rigidity and dimensional accuracy are critical. The 1/4-inch shank diameter keeps it compatible with standard toolpost and turret setups. At 2.5 inches overall length and just 0.05 pounds, it is compact and easy to handle during setup. Machinists and toolroom operators working in steel, aluminum, and similar materials will find this bar suited to production and prototype boring applications alike.

This boring bar is intended for right-hand cutting operations in internal boring applications on lathes and turning machines. It is well suited for residential and commercial machine shop environments where small-diameter, shallow-bore work is required. The solid carbide construction provides the stiffness needed to maintain bore geometry at small diameters, reducing chatter and improving surface finish in typical finish-boring scenarios.

Key Features

• Solid carbide construction for maximum rigidity and reduced deflection in small-bore applications
• Minimum bore diameter of 0.2000 inches for precision small-diameter internal work
• Maximum bore depth of 1 inch suits typical shallow-bore finishing operations
• Right-hand cutting direction for standard lathe and turning center setups
• 1/4-inch shank diameter compatible with common toolpost and turret holders
• Compact 2.5-inch overall length simplifies tool changes and setup

Compatibility

Designed as an OEM-style replacement and standard tooling option for lathes and turning centers accepting a 1/4-inch shank boring bar with right-hand cutting orientation.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before mounting or adjusting the boring bar in the tool holder. Ensure the shank is properly clamped to the specified holder depth to minimize overhang and reduce vibration during the cut. Follow the machine manufacturer guidelines for tool offset entry and trial cuts before running to final dimension.
