Accupro ACC-BB100400A Boring Bar 0.1in Min Bore Solid Carbide

Product Description

The ACCUPRO ACC-BB100400A is a solid carbide boring bar designed for precision internal boring operations on lathes and turning centers. Built from micrograin solid carbide with a TiAlN finish coating, it delivers consistent cutting performance and extended tool life in demanding machining environments. The bar features a right-hand cutting direction, a minimum bore diameter of 0.1 inches, a maximum bore depth of 0.4 inches, a shank diameter of 0.125 inches, and an overall length of 1.5 inches. It is suited for machinists and toolroom technicians working on small-diameter bores in ferrous and non-ferrous materials.

This boring bar is intended for small-bore internal turning applications where tight tolerances and fine surface finishes are required. Its compact shank diameter and short overall length make it appropriate for use in micro-boring and watchmaker-scale work, as well as general toolroom and production turning setups where minimum bore diameter is in the 0.1-inch range. The micrograin carbide substrate supports high cutting speeds and resists chipping at small depths of cut.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-bore applications
• TiAlN finish coating for improved heat resistance and extended tool life
• Right-hand cutting direction for standard lathe and turning center setups
• 0.1-inch minimum bore diameter enables precise work on very small internal features
• 0.125-inch shank diameter fits standard small-bore toolholders and collet chucks
• 1.5-inch overall length provides compact reach suitable for shallow boring applications

Compatibility

Designed as an OEM-style replacement or production tooling option for small-bore boring bar holders and collet-style tooling systems accepting a 0.125-inch round shank.

Installation Notes

Installation is performed by qualified machinists on lathes or CNC turning centers. Ensure the machine spindle is fully stopped and the machine is placed in a locked or e-stop state before changing or seating tooling. Secure the shank firmly in the toolholder to minimize overhang and reduce vibration during the cut. Follow the toolholder manufacturer's clamping specifications and applicable shop safety procedures.
