Micro 100 BB-060300S Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-060300S is a solid carbide boring bar designed for precision internal turning operations on CNC lathes and manual turning centers. It features a 0.060-inch minimum bore diameter and a 0.300-inch maximum bore depth, making it well suited for tight, small-diameter bores where rigidity and dimensional accuracy are critical. The 1/8-inch shank diameter and 1.5-inch overall length allow it to fit compact tooling setups without sacrificing stability. Right-hand cutting orientation is standard. Machinists and toolroom technicians install this bar in applications where solid carbide construction is required to maintain tolerances and resist deflection in challenging workpiece materials.

This boring bar is intended for small-bore finish and semi-finish turning in precision machining environments. It performs well in production shops, tool and die operations, and job shop settings where consistent bore geometry is required. The solid carbide construction is appropriate for hardened materials, non-ferrous alloys, and other workpiece materials that demand a rigid cutting tool. Its compact size makes it a practical choice for watchmaking components, hydraulic fittings, medical device parts, and similar tight-tolerance work.

Key Features

• Solid carbide construction provides rigidity and resistance to deflection in small-bore applications
• 0.060-inch minimum bore diameter enables access to very small internal diameters
• 0.300-inch maximum bore depth suits shallow through and blind bore operations
• Right-hand cutting direction for standard lathe rotation setups
• 1/8-inch shank diameter fits common small-bore toolholders and quick-change systems
• 1.5-inch overall length keeps overhang minimal for improved stability

Compatibility

Designed as an OEM-style replacement and standard-fit boring bar for toolholders accepting a 1/8-inch shank diameter in right-hand boring configurations on CNC and manual lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in a compatible boring bar holder and verify that tool overhang does not exceed recommended guidelines for the shank diameter. Power down and lock out the machine spindle before changing or adjusting tooling. Confirm cutting direction and tool orientation match the machine setup before initiating a cut.
