Accupro ACC-BB2301500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB2301500 is a solid carbide boring bar engineered for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, it delivers consistent cutting performance in tight-tolerance bore work. The bar accepts a minimum bore diameter of 0.23 inches and reaches a maximum bore depth of 1-1/2 inches, making it well-suited for short, accurate blind or through bores. With a 5/16 inch shank diameter and an overall length of 2-1/2 inches, this compact tool fits standard boring bar holders used by machinists and toolroom operators in production and job-shop environments.

This boring bar is intended for right-hand cutting and is designed for use in small-bore finishing and semi-finishing applications. Its submicron carbide construction makes it appropriate for machining ferrous and non-ferrous workpieces where surface finish and dimensional accuracy are critical. Typical applications include bore sizing in precision components, fixture work, and repair machining where a compact, rigid tool is required. The bright coating leaves the carbide substrate exposed for visual wear monitoring during use.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance
• Minimum bore diameter of 0.23 inches for small-bore precision work
• Maximum bore depth of 1-1/2 inches suits blind and through-bore applications
• Right-hand cutting direction compatible with standard lathe spindle rotation
• Bright finish allows visual inspection of cutting edge and flank wear
• Compact 2-1/2 inch overall length reduces overhang and chatter risk

Compatibility

Designed as an OEM-style replacement and standard tooling option for boring bar holders accepting a 5/16 inch shank diameter in CNC and manual turning applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully within the boring bar holder to the recommended grip length to minimize deflection and vibration. Ensure the machine spindle is fully stopped and the machine is placed in a safe state before inserting or removing the tool. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running test cuts.
