Micro 100 QBB-2301500X Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 QBB-2301500X is a solid carbide boring bar designed for internal bore finishing and sizing operations on CNC lathes and manual turning centers. It produces right-hand cuts with a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1.5 inches. The 5/16-inch shank diameter and 3-inch overall length make this bar compatible with standard tool holders used in production and job-shop environments. Solid carbide construction provides rigidity and wear resistance needed for tight-tolerance bores in ferrous and non-ferrous materials. Licensed machinists and toolroom operators are the primary users.

This boring bar suits precision turning operations where bore diameter accuracy and surface finish are critical. It is a right-hand cut tool, meaning it removes material as the workpiece rotates in the conventional forward direction. Typical applications include finishing bores in machined components such as housings, bushings, and sleeves. The 0.005-inch corner radius controls the blend at the bore bottom and affects surface finish at the transition. It fits well in both light-production and prototype machining setups.

Key Features

• Solid carbide construction for rigidity and extended tool life in precision boring
• Minimum bore diameter of 0.23 inches allows work in tight, small-diameter bores
• Maximum bore depth of 1.5 inches suits a wide range of standard component depths
• Right-hand cutting direction for conventional lathe rotation
• 0.005-inch corner radius for controlled surface finish at bore transitions
• 5/16-inch shank diameter fits standard boring bar tool holders

Compatibility

Designed as a direct-fit replacement or addition for standard 5/16-inch shank boring bar holders used in CNC and manual turning applications requiring a minimum bore of 0.23 inches.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before seating or removing the boring bar from the tool holder. Ensure the shank is fully engaged and clamping screws are tightened per the tool holder specification. Do not exceed the maximum bore depth of 1.5 inches, as overhang beyond rated depth increases deflection and risk of tool breakage.
