Accupro ACC-BB140800A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB140800A is a micrograin solid carbide boring bar designed for small-diameter internal turning and bore finishing operations on CNC lathes and manual turning centers. With a minimum bore diameter of 0.14 inches and a maximum bore depth of 0.8 inches, this bar is suited for tight, shallow bore work that demands rigidity and dimensional consistency. The 3/16-inch shank diameter and 2-inch overall length keep the tool compact for close-clearance setups. A TiAlN finish coating provides heat resistance and extended tool life when cutting ferrous and hard materials at elevated surface speeds.

This boring bar is used in precision machining environments including job shops, production turning cells, and toolroom operations. It is appropriate for finishing and semi-finishing passes in ferrous metals, hardened steels, and similar materials where a micrograin carbide substrate and TiAlN coating deliver consistent results. The right-hand cutting direction suits standard turning center orientations. Machinists working on small bores in medical, aerospace, or general precision components will find this bar fits typical small-bore tooling requirements.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance in small-bore applications
• TiAlN finish coating improves heat resistance and extends tool life in ferrous and hard material cuts
• 0.14-inch minimum bore diameter enables access to very small internal diameters
• 0.8-inch maximum bore depth supports shallow to moderate bore length ratios
• 3/16-inch shank diameter fits compact and close-clearance toolholders
• Right-hand cutting direction for standard lathe and turning center setups

Compatibility

Designed as an OEM-style replacement and standard fit for turning centers and CNC lathes accepting a 3/16-inch round shank boring bar.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols and machine tool manufacturer guidelines. Power down and lock out the turning center before mounting or removing any tooling. Secure the shank fully within the toolholder to the recommended engagement depth per the toolholder manufacturer to prevent deflection or pullout. Inspect the bore bar for chips, cracks, or coating damage before use.
