Micro 100 BB-2901250SX Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-2901250SX is a solid carbide boring bar designed for internal diameter machining in metal cutting applications. It features a minimum bore diameter of 0.29 inches and a maximum bore depth of 1.25 inches, making it well suited for small-diameter, precision boring operations. The shank diameter measures 5/16 inches, and the overall length is 2.5 inches. Right-hand cut geometry directs cutting forces and chip flow in the standard direction for conventional lathe and boring mill setups. Machinists, toolroom operators, and CNC setup technicians install this type of tooling in turning centers and boring mills where tight bore tolerances are required.

This boring bar is intended for use in precision machining environments where small minimum bore diameters are critical. It is appropriate for short-run toolroom work and production CNC turning applications. The solid carbide construction provides rigidity and wear resistance in ferrous and non-ferrous materials. Right-hand cutting direction suits standard spindle rotation on most lathes and CNC turning centers. The compact 2.5-inch overall length keeps the tool extension short, reducing chatter risk in tight setups.

Key Features

• Solid carbide construction for rigidity and extended tool life
• Minimum bore diameter of 0.29 inches for small-diameter internal work
• Maximum bore depth of 1.25 inches
• 5/16-inch shank diameter for compatible tool holders
• Right-hand cut direction for standard lathe and CNC turning center setups
• Compact 2.5-inch overall length reduces overhang and chatter

Compatibility

Designed as a replacement or standard boring bar for use in tool holders accepting a 5/16-inch round shank, common on lathes and CNC turning centers configured for small-diameter internal boring work.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or adjusting the boring bar in the tool holder. Ensure the shank is fully seated and clamped securely to the specified holder torque per the machine tool manufacturer guidelines. Verify boring bar centerline height relative to the workpiece centerline before initiating a cut.
