Accupro B2301600A Boring Bar 0.23in Min Bore Solid Carbide

Product Description

The ACCUPRO B2301600A is a solid carbide boring bar designed for precision internal boring operations on CNC and manual lathes. Built from submicron-grade carbide and finished with an AlTiN coating, this bar delivers extended tool life in hard and abrasive workpiece materials. It cuts in a right-hand direction and accepts a 5/16-inch shank diameter. The minimum bore diameter is 0.23 inches, making it well suited for small-diameter internal features. Maximum bore depth is 1.6 inches, and overall length is 2.5 inches. Machinists and toolroom operators handling precision turning and boring work will find this bar a dependable option for tight-tolerance applications.

This boring bar is appropriate for use in job shops, production machining environments, and toolroom settings where small-bore internal diameters require consistent, repeatable results. The right-hand cutting geometry suits standard lathe setups. The AlTiN coating provides thermal resistance and reduced friction, making it effective in dry or minimally lubricated cutting conditions common in steel, stainless, and high-temp alloy work. Typical installation is in a boring bar holder or quick-change toolpost on a manual or CNC turning center.

Key Features

• Submicron solid carbide construction for high wear resistance and edge retention
• AlTiN finish coating provides thermal resistance for elevated cutting speeds and dry machining
• Right-hand cut geometry for standard lathe and turning center setups
• 0.23-inch minimum bore diameter enables work on small internal features
• 1.6-inch maximum bore depth with 5/16-inch shank diameter for secure toolholder engagement
• 2.5-inch overall length supports compact toolholder setups and short overhangs

Compatibility

Designed as a direct-fit replacement or new installation for standard 5/16-inch boring bar holders used in manual and CNC turning centers requiring right-hand cut tooling with a 0.23-inch minimum bore capability.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in a compatible 5/16-inch boring bar holder and verify that toolholder set screws are properly tightened before operation. Power down and lock out the machine spindle before changing or adjusting tooling. Do not exceed the maximum bore depth of 1.6 inches, as overextension can cause deflection and tool breakage.
