Micro 100 BB-180350G Boring Bar Solid Carbide Right Hand

Product Description

The MICRO 100 BB-180350G is a solid carbide boring bar designed for precision internal diameter machining on CNC lathes and manual turning centers. It features a minimum bore diameter of 0.180 inches and a maximum bore depth of 0.350 inches, making it well suited for tight-tolerance small-bore work. The 1/4-inch shank diameter provides a secure toolholder interface, and the 0.006-inch corner radius supports clean finishes in confined bore geometries. Overall length is 2.5 inches. Machinists and toolroom professionals install this bar when close-tolerance internal features require carbide rigidity and consistent edge geometry.

This boring bar is intended for right-hand cutting operations in small-bore applications found in precision machining environments, including job shops, production turning cells, and toolroom setups. It is suited for ferrous and non-ferrous workpiece materials where a solid carbide body offers the rigidity needed to minimize chatter and hold dimensional tolerances in shallow internal bores up to 0.350 inches deep.

Key Features

• Solid carbide construction for high rigidity and reduced deflection in small-bore applications
• Minimum bore diameter of 0.180 inches for tight internal features
• Maximum bore depth of 0.350 inches
• Right-hand cutting direction
• 0.006-inch corner radius for controlled surface finish
• 1/4-inch shank diameter for standard toolholder compatibility

Compatibility

Designed as an OEM-style replacement and direct-fit boring bar for 1/4-inch shank boring bar toolholders used in precision CNC and manual turning applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secure before inserting or removing the bar. Verify shank seating depth and toolholder clamping torque per the toolholder manufacturer specifications. Do not exceed the rated maximum bore depth of 0.350 inches to avoid deflection or tool breakage.
