Micro 100 BB-120500S Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-120500S is a solid carbide boring bar designed for internal diameter machining on lathes and turning centers. It accepts a minimum bore diameter of 0.12 inches and handles a maximum bore depth of 0.5 inches, making it well suited for small, precise bores where rigidity and surface finish matter. The 3/16-inch shank diameter keeps the tool compact, and the bright, uncoated carbide surface is ready for use as delivered. Machinists and tool-and-die professionals install this bar when tight tolerances on small bores require a stiff, vibration-resistant tool material.

This boring bar is intended for right-hand cutting operations on CNC and manual turning equipment. It fits applications where bore diameters start at 0.12 inches, including small hydraulic components, bushings, and precision housings. The 2-inch overall length suits standard toolholders used in both production and job-shop environments. The solid carbide construction supports higher cutting speeds and finer finishes than high-speed steel alternatives, making it a practical choice for ferrous and non-ferrous materials at close tolerances.

Key Features

• Solid carbide construction provides high rigidity and wear resistance in small-bore applications
• Minimum bore diameter of 0.12 inches for tight internal diameter work
• Maximum bore depth of 0.5 inches suits shallow precision bores
• Right-hand cutting direction for standard lathe and turning center setups
• Bright, uncoated finish - no coating removal needed before first use
• 3/16-inch shank diameter and 2-inch overall length for compact toolholder compatibility

Compatibility

Designed as an OEM-style boring bar for use in standard small-bore toolholders accepting a 3/16-inch shank diameter on CNC and manual turning equipment.

Installation Notes

Installation is performed by qualified machinists following shop safety procedures and applicable machine tool codes. Secure the shank fully in the toolholder to the recommended grip length before operation, and verify tool overhang is minimized to reduce deflection. Ensure the machine spindle is fully stopped and the control is in an safe state before changing or adjusting the boring bar. Do not exceed the tool manufacturer's recommended depth-of-cut for the bore diameter being machined.
