Accupro ACC-BB3201500A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB3201500A is a solid carbide boring bar designed for internal turning and boring operations on CNC lathes and manual turning centers. Built from micrograin solid carbide with a TiAlN finish coating, it delivers the hardness and edge retention needed for tight-tolerance bore work. The bar has a 0.32 inch minimum bore diameter and a maximum bore depth of 1.5 inches, making it well-suited for small-diameter, moderate-depth applications. The 3/8 inch shank diameter and 2.5 inch overall length give it a compact, rigid profile. Right-hand cutting geometry is standard. This tool is installed and used by machinists and CNC operators in production and job-shop environments.

This boring bar is used in applications requiring precise bore sizing in metals including steel, cast iron, and non-ferrous alloys. The micrograin carbide substrate provides wear resistance and edge stability under interrupted cuts and continuous turning passes. The TiAlN coating adds heat resistance, extending tool life in dry or minimal-lubrication machining conditions. Typical installs include finish-boring pre-drilled or rough-bored holes to final diameter in short to medium production runs where dimensional accuracy is critical.

Key Features

• Micrograin solid carbide construction for superior edge retention and rigidity
• TiAlN finish coating for elevated heat resistance and extended tool life
• 0.32 inch minimum bore diameter for small-bore precision work
• 1.5 inch maximum bore depth for moderate-depth applications
• Right-hand cutting direction for standard lathe setup
• 3/8 inch shank diameter fits common boring bar holders and turrets

Compatibility

Designed for use in standard 3/8 inch boring bar holders on CNC lathes, manual turning centers, and machining center boring heads that accept round-shank tooling.

Installation Notes

Installation is performed by machinists or tooling technicians. Secure the shank fully in the holder with adequate clamping length to minimize overhang and reduce chatter. Power down and lock out the machine spindle before changing or adjusting tooling. Verify bore diameter with a calibrated bore gauge after initial test cuts before running production.
