Accupro ACC-BB360500A Boring Bar Solid Carbide Tialn

Product Description

The ACCUPRO ACC-BB360500A is a solid carbide boring bar designed for internal turning and bore finishing operations on CNC lathes and manual turning centers. Built from micrograin solid carbide, it delivers superior hardness and edge retention compared to standard carbide grades. The TiAlN finish coating adds heat and oxidation resistance, extending tool life in dry and semi-dry cutting conditions. With a minimum bore diameter of 0.36 inches and a maximum bore depth of 0.50 inches, this bar is suited for tight, shallow bores where rigidity and precision matter. It is installed and operated by machinists and toolroom technicians in production and job-shop environments.

This boring bar is configured for right-hand cutting direction, making it compatible with conventional forward-feed lathe operations. The 3/8 inch shank diameter fits standard boring bar holders and quick-change toolpost systems commonly found on small to mid-size turning centers. With an overall length of 2.5 inches, it provides a compact profile that minimizes overhang and vibration during cuts. Typical applications include finishing bores in ferrous metals, aluminum, and hard alloys where dimensional accuracy and surface finish are critical.

Key Features

• Micrograin solid carbide construction for high hardness and extended edge life
• TiAlN finish coating for improved heat resistance in dry and semi-dry machining
• Right-hand cutting direction for standard forward-feed lathe operations
• Minimum bore diameter of 0.36 inches for tight internal features
• Maximum bore depth of 0.50 inches keeps overhang low and reduces chatter
• 3/8 inch shank diameter fits standard boring bar holders and quick-change systems

Compatibility

Designed as a direct-fit replacement for 3/8 inch shank boring bar holders used on small to mid-size CNC and manual turning centers requiring right-hand internal boring tooling.

Installation Notes

This boring bar is installed by machinists using a calibrated boring bar holder or quick-change toolpost block sized for a 3/8 inch shank. Before mounting, ensure the lathe spindle is fully stopped and all power is locked out per shop lockout/tagout procedures. Set tool height on center using a tool height gauge to avoid rubbing and premature edge wear. Do not exceed the recommended bore depth of 0.50 inches to maintain rigidity and prevent tool deflection.
