Micro 100 QBB-110300-000X Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 QBB-110300-000X is a solid carbide boring bar designed for precision internal diameter machining in tight-tolerance applications. With a minimum bore diameter of 0.110 inches (2.80 mm) and a maximum bore depth of 0.300 inches, this bar handles small-bore work where rigidity and dimensional accuracy are critical. The 3/16-inch shank diameter and 1.5-inch overall length make it suitable for use in compact setups on CNC lathes, machining centers, and manual turning equipment. Machinists and tooling specialists installing or setting up precision boring operations are the primary users of this tool.

This boring bar is suited for right-hand cutting operations in small-bore internal machining applications. Typical use cases include finish boring of small holes in ferrous and non-ferrous materials where close tolerances are required. The solid carbide construction supports higher speeds and feeds compared to steel-bodied alternatives, making it appropriate for production and job-shop environments where surface finish and bore geometry matter.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-bore applications
• Minimum bore diameter of 0.110 inches (2.80 mm) for tight internal geometry work
• Maximum bore depth of 0.300 inches for shallow to moderate bore lengths
• Right-hand cutting direction for standard lathe and boring setups
• 3/16-inch shank diameter for compatibility with standard toolholding systems
• Compact 1.5-inch overall length minimizes overhang and deflection

Compatibility

Designed as an OEM-style boring bar for use in standard toolholding systems that accept a 3/16-inch round shank, suitable for CNC and manual turning or milling setups requiring small-bore internal machining capability.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with boring bar toolholding and small-bore operations. Ensure the machine spindle is fully stopped and locked out before inserting or adjusting the boring bar in the toolholder. Minimize shank stick-out to reduce deflection and maintain bore accuracy. Verify workholding and part fixturing are secure before initiating a cut.
