Micro 100 BB-2901500 Solid Carbide Boring Bar 0.290in

Product Description

The MICRO 100 BB-2901500 is a solid carbide boring bar designed for precision internal turning and bore finishing operations on metalworking lathes and boring machines. It features a minimum bore diameter of 0.290 inches and a maximum bore depth of 1.5 inches, making it well suited for small-diameter through and blind bore work. The 5/16-inch shank diameter provides rigid tool holding, and the 0.0060-inch corner radius supports accurate, repeatable cuts with controlled surface finish. Solid carbide construction delivers the hardness and wear resistance required for consistent performance in ferrous and non-ferrous materials. Licensed machinists and toolroom professionals are the primary installers and operators of this tool.

This boring bar is intended for use in precision machining environments where tight bore tolerances are required. It is a right-hand cutting tool, appropriate for conventional lathe setups where the spindle rotates counterclockwise when viewed from the tailstock. The 2.5-inch overall length suits compact workpieces and short-overhang setups. Typical applications include bore sizing, finishing, and light material removal on production runs or custom fabrication work requiring close-tolerance internal diameters.

Key Features

• Solid carbide construction for high hardness and extended tool life
• Minimum bore diameter of 0.290 inches for small-bore applications
• Maximum bore depth of 1.5 inches suits through and blind bore operations
• Right-hand cutting direction for standard lathe setups
• 0.0060-inch corner radius for controlled surface finish
• 5/16-inch shank diameter for rigid, repeatable tool holding

Compatibility

Designed as a direct-fit boring bar for standard tool holders and boring heads accepting a 5/16-inch shank, suitable for use on manual and CNC lathes configured for right-hand internal turning operations.

Installation Notes

This tool is installed and operated by qualified machinists following standard shop safety practices. Power down and lock out the spindle before changing or adjusting tooling. Secure the shank fully within the tool holder to the minimum recommended engagement depth to prevent chatter and deflection. Do not exceed the rated bore depth or attempt to use this tool as a left-hand cutter.
