Accupro ACC-BB2901500A Boring Bar Micrograin Carbide Tialn

Product Description

The ACCUPRO ACC-BB2901500A is a solid carbide boring bar designed for precision internal boring operations on lathes and machining centers. Built from micrograin carbide stock and finished with a TiAlN coating, it delivers wear resistance and thermal stability in demanding cutting applications. The bar handles a minimum bore diameter of 0.29 inches and a maximum bore depth of 1.5 inches, making it well suited for small-diameter, short-reach bores where rigidity and accuracy are critical. The 5/16-inch shank diameter and 2.5-inch overall length give machinists a compact, stiff tool body that minimizes deflection at depth.

This boring bar is intended for use in job shops, tool rooms, and production machining environments where tight tolerances on bored features are required. It is appropriate for ferrous and non-ferrous materials in applications calling for a right-hand cutting direction. The right-hand cut configuration fits standard boring bar holders and quick-change tool posts commonly found on manual and CNC lathes. It is installed and operated by machinists, toolroom technicians, and CNC setup personnel.

Key Features

• Micrograin solid carbide construction for improved rigidity and edge retention over standard carbide grades
• TiAlN finish coating provides enhanced heat resistance and extended tool life in dry and semi-dry cutting conditions
• Minimum bore diameter of 0.29 inches supports small-diameter internal boring applications
• Maximum bore depth of 1.5 inches suitable for short-reach precision bores
• 5/16-inch shank diameter compatible with standard boring bar holders and tool posts
• Right-hand cutting direction for conventional lathe setup orientation

Compatibility

Designed as an OEM-style replacement and standard tooling option for boring bar holders accepting a 5/16-inch shank with right-hand cutting orientation on manual and CNC lathes.

Installation Notes

This boring bar is installed by machinists and toolroom technicians following standard lathe tooling practices. Power down and lock out the machine before securing the bar in the tool holder, ensuring the shank is fully seated and clamped to the specified holder requirements. Do not exceed the maximum bore depth rating of 1.5 inches, as overhang beyond rated depth increases deflection and risk of tool failure. Verify cutting direction and clearance angles match the workpiece setup before initiating a cut.
