Accupro ACC-BB3603000G Boring Bar Micrograin Solid Carbide

Product Description

The ACCUPRO ACC-BB3603000G is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a titanium nitride (TiN) finish coating, this bar delivers consistent dimensional accuracy and extended tool life in ferrous and non-ferrous materials. It features a right-hand cutting direction, a minimum bore diameter of 0.36 inches, and a maximum bore depth of 3 inches. The 3/8-inch shank diameter and 4-inch overall length make it well suited for tight-tolerance bores in production and job-shop environments. Machinists and tool room technicians are the primary users.

This boring bar is used in applications where precise internal diameters are required, including through-holes and blind bores in turned components. It is appropriate for both roughing and finishing passes within its bore diameter range. The TiN coating reduces friction and improves wear resistance, making it effective in medium- to high-volume turning operations. Typical installations include automated CNC turning programs and manually controlled lathe setups where a 3/8-inch shank toolholder is available.

Key Features

• Micrograin solid carbide construction for high rigidity and wear resistance
• TiN finish coating reduces friction and extends tool life
• Right-hand cutting direction for standard lathe setups
• 0.36-inch minimum bore diameter supports tight internal geometry
• 3-inch maximum bore depth allows work on deeper bores without tool change
• 3/8-inch shank diameter fits common boring bar toolholders

Compatibility

Designed for use in 3/8-inch shank boring bar toolholders on CNC and manual lathes. Verify toolholder bore diameter and minimum bore clearance before installation.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Secure the shank fully within the toolholder and confirm overhang is minimized to reduce chatter and deflection. Power down the machine and lock out all motion before changing or adjusting tooling. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running first-pass cuts.
