Micro 100 BB-3201000 Boring Bar Right Hand Solid Carbide

Product Description

The MICRO 100 BB-3201000 is a solid carbide boring bar designed for precision internal turning and boring operations on CNC and manual lathes. It accepts a minimum bore diameter of 0.32 inches with a maximum bore depth of 1 inch, making it suited for tight, shallow bore applications where rigidity and dimensional accuracy are critical. The 0.375-inch shank diameter and 2.5-inch overall length provide a compact, stable setup. A 0.006-inch corner radius delivers a controlled edge finish appropriate for finishing passes in ferrous and non-ferrous materials. Machinists and tool-and-die professionals typically spec this bar for close-tolerance work where chatter control and tool deflection are primary concerns.

This boring bar is intended for use in machine shop environments on lathes, boring mills, and machining centers requiring internal diameter work on small bores. The right-hand cutting direction suits standard spindle rotation on conventional setups. Its solid carbide construction supports higher surface footage and longer tool life compared to high-speed steel alternatives, particularly in harder workpiece materials or high-production runs.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding bore applications
• Minimum bore diameter of 0.32 inches for small-diameter internal turning
• Maximum bore depth of 1 inch suitable for shallow to moderate depth bores
• 0.375-inch shank diameter for secure tool holder clamping
• 0.006-inch corner radius for controlled surface finish on finishing passes
• Right-hand cut configuration for standard lathe spindle rotation

Compatibility

Designed for use in tool holders accepting a 0.375-inch round shank, compatible with CNC lathes, manual engine lathes, and boring mills configured for right-hand internal boring operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Power down and lock out the spindle before mounting or removing the boring bar. Seat the shank fully in the tool holder and tighten set screws to the tool holder specification to minimize overhang and reduce deflection. Inspect the cutting edge for chipping before each use, as carbide tooling is brittle and susceptible to damage from interrupted cuts or improper handling.
