Micro 100 QBB-1601000X Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 QBB-1601000X is a solid carbide boring bar designed for precision internal diameter machining on lathes and boring mills. It features a 0.160-inch minimum bore diameter and a 3/16-inch shank diameter, making it suited for tight-bore applications where rigidity and dimensional accuracy are critical. With a 0.0030-inch corner radius and a right-hand cutting direction, it produces clean, consistent finishes in small-bore work. Machinists and tool room operators working on close-tolerance parts will find this bar appropriate for production and job shop environments alike.

This boring bar is intended for small-bore internal turning operations on CNC lathes, manual lathes, and boring mills. Its solid carbide construction provides the stiffness required to minimize deflection in deep relative to diameter boring passes. The 1-inch maximum bore depth and 2-inch overall length make it a practical choice for short-run and production setups where a compact, rigid tool is needed. It is suited for ferrous and non-ferrous workpiece materials where fine surface finish and diameter control are priorities.

Key Features

• Solid carbide construction minimizes tool deflection in small-bore operations
• 0.160-inch minimum bore diameter enables machining of tight internal features
• 0.0030-inch corner radius supports fine surface finish requirements
• Right-hand cutting direction for standard lathe and boring mill setups
• 3/16-inch shank diameter fits common small-bore toolholders
• 2-inch overall length keeps the tool compact and rigid

Compatibility

Designed as an OEM-style replacement and standard tooling solution for small-bore boring bar toolholders accepting a 3/16-inch shank diameter on CNC and manual lathes.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with lathe tooling and boring operations. Secure the shank firmly in a compatible toolholder, ensuring minimum overhang to reduce vibration and deflection. Power down the machine and confirm the spindle is fully stopped before mounting or removing the tool. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool height and boring parameters.
