Micro 100 BB-100300 Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-100300 is a solid carbide boring bar designed for precision internal turning operations on small-diameter bores. It features a minimum bore diameter of 0.1 inches and a maximum bore depth of 0.3 inches, making it well suited for tight, shallow bore applications where rigidity and accuracy are critical. The 1/8-inch shank diameter and 1.5-inch overall length keep the tool compact and easy to set in small lathes or machining centers. A 0.003-inch corner radius allows for precise contour control at the cutting edge. This bar is uncoated solid carbide, offering the hardness needed for consistent performance in ferrous and non-ferrous materials.

The BB-100300 is used in CNC lathe, manual lathe, and machining center applications where small internal bores require a rigid, right-hand cut tool. It is a common choice for machinists working on precision components such as bushings, fittings, and small bored housings where bore diameter tolerances are tight and tool deflection must be minimized. The compact overall length and small shank diameter make it practical for Swiss-style and gang-tool setups as well.

Key Features

• Solid carbide construction for high rigidity and wear resistance
• Minimum bore diameter of 0.1 inches suits very small internal features
• Maximum bore depth of 0.3 inches with a 0.003-inch corner radius for controlled contouring
• Right-hand cutting direction for standard lathe and machining center use
• Uncoated finish suitable for a wide range of workpiece materials
• 1/8-inch shank diameter and 1.5-inch OAL for compact tool setups

Compatibility

Designed as an OEM-style replacement or direct-use boring bar for lathes and machining centers accepting a 1/8-inch shank boring tool with right-hand cut orientation.

Installation Notes

Installation of boring bars should be performed by a qualified machinist following the machine tool manufacturer's setup guidelines. Secure the shank firmly in the tool holder with minimal overhang to reduce deflection and chatter. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing or adjusting tooling. Verify bore depth and diameter settings with appropriate gauging before running production cuts.
