Accupro B2001100A Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO B2001100A is a solid carbide boring bar designed for precision internal boring operations on lathes and machining centers. Built from submicron-grade carbide and finished with an AlTiN coating, it delivers high wear resistance and thermal stability during cutting. The right-hand cutting geometry suits standard spindle rotation setups. With a 0.25 inch shank diameter and 2.5 inch overall length, this bar fits compact tool holders and provides rigid support in tight-bore applications. It handles a minimum bore diameter of 0.2 inches and a maximum bore depth of 1.1 inches, making it well suited for small-diameter precision work in ferrous and hardened materials.

This boring bar is used in CNC turning and manual lathe operations where close-tolerance internal diameters are required. It is appropriate for job shops, production machining environments, and tool rooms working with steel, stainless steel, cast iron, and similar materials. The submicron carbide grade and AlTiN coating extend tool life in interrupted cuts and at elevated cutting speeds. Machinists and CNC operators handling small-bore finishing and semi-finishing work will find this bar a practical fit for those applications.

Key Features

• Submicron solid carbide construction for high hardness and edge retention
• AlTiN finish coating provides oxidation resistance and reduces heat buildup at the cutting edge
• Right-hand cutting direction compatible with standard lathe spindle rotation
• 0.2 inch minimum bore diameter suited for small-bore precision work
• 1.1 inch maximum bore depth for controlled internal reach
• 0.25 inch shank diameter fits common small-bore tool holders

Compatibility

Designed as a direct-fit boring bar for tool holders accepting a 0.25 inch round shank, commonly used in CNC turning centers and manual lathes configured for small-diameter internal boring.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank fully within the tool holder to the manufacturer-recommended minimum engagement length before operation. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing or adjusting tooling. Follow the machine tool builder guidelines and applicable shop safety standards when setting tool offsets and trial-cutting a new boring bar.
