Accupro ACC-BBL230800 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL230800 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 coating, this bar delivers tight dimensional control and extended tool life in ferrous and non-ferrous materials. It cuts in a left-hand direction with a minimum bore diameter of 0.23 inches and a maximum bore depth of 0.8 inches. The 5/16-inch shank diameter and 2.5-inch overall length suit compact tooling setups where clearance and rigidity both matter. Machinists and tooling technicians spec this bar when holding close tolerances in small-diameter bores.

This boring bar is suited for light to medium internal turning applications in production and job-shop environments. The left-hand cutting direction makes it appropriate for back-boring operations or setups requiring reverse-feed toolpaths. Its submicron carbide grade supports use in interrupted cuts and harder workpiece materials where standard carbide grades lose edge life prematurely. The compact geometry fits swiss-type and gang-tool lathes as well as conventional turning centers equipped with small-bore toolholders.

Key Features

• Submicron solid carbide construction for extended edge life and dimensional stability
• Left-hand cutting direction supports back-boring and reverse-feed applications
• 0.23-inch minimum bore diameter enables access to small internal diameters
• 0.8-inch maximum bore depth suits shallow to moderate bore lengths
• Bright finish coating reduces built-up edge in non-ferrous and softer materials
• 5/16-inch shank diameter fits standard small-bore toolholders and gang-tool blocks

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 5/16-inch bore toolholders on CNC and manual turning centers.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth before running the spindle. Confirm left-hand spindle rotation or reverse-feed programming matches the cutting direction of this bar before engaging the workpiece. Inspect the cutting edge for chips or wear before each use, as carbide tools should not be run with damaged edges.
