Accupro ACC-BB110400 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB110400 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, this tool delivers the rigidity and wear resistance required for tight-tolerance bores in hard and abrasive workpiece materials. The bar handles a minimum bore diameter of 0.11 inches and a maximum bore depth of 0.4 inches, making it well suited for small-diameter, shallow-bore applications. With a 1/8-inch shank diameter and an overall length of 1.5 inches, it fits compact tooling setups where clearance and reach are constrained. Right-hand cut geometry supports conventional lathe rotation and standard boring cycles.

This boring bar is intended for machining professionals working with small-bore components in production or job-shop environments. It is particularly useful when boring miniature features in stainless steel, hardened steels, cast iron, or high-temp alloys where submicron carbide grain structure provides a measurable edge life advantage over standard carbide grades. The compact overall length keeps deflection minimal in shallow-bore pass applications.

Key Features

• Submicron solid carbide construction for extended tool life in hard and abrasive materials
• Minimum bore diameter of 0.11 inches enables work on small, tight-tolerance features
• Maximum bore depth of 0.4 inches suited to shallow internal boring passes
• 1/8-inch shank diameter fits standard small-bore toolholders and turret blocks
• Bright finish coating reduces built-up edge and aids chip evacuation
• Right-hand cut geometry for standard lathe rotation and conventional boring cycles

Compatibility

Designed as a direct-fit replacement or supplemental tooling for small-bore turning and boring applications using toolholders with a 1/8-inch shank bore, consistent with standard CNC lathe and manual turning center setups.

Installation Notes

Installation is performed by qualified machinists or tooling setup technicians. Secure the shank fully in the toolholder bore and confirm that stick-out does not exceed what is necessary for the bore depth to minimize deflection. Power down and lock out the machine spindle before changing or adjusting tooling. Verify bore diameter and depth with a calibrated gauge before committing to a full production run.
