Accupro ACC-BB160900 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB160900 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade solid carbide with a bright finish, it delivers consistent dimensional accuracy in tight-tolerance bores. The right-hand cutting geometry suits standard spindle rotation setups. With a minimum bore diameter of 0.16 inches and a maximum bore depth of 0.9 inches, this bar handles small-diameter work where rigidity and tool geometry are critical. It is used by machinists and toolroom technicians working in production and job-shop environments.

This boring bar is suited for light to medium internal turning in ferrous and non-ferrous materials where bore diameter and depth constraints demand a compact, rigid tool. The 3/16-inch shank diameter fits standard boring bar holders and quick-change tooling systems configured for small-diameter work. Typical applications include finish boring of close-tolerance holes in components such as bushings, hydraulic bodies, and precision housings. The submicron carbide grade supports longer tool life compared to standard carbide grades in abrasive or interrupted-cut conditions.

Key Features

• Submicron solid carbide construction for enhanced rigidity and wear resistance
• Right-hand cutting direction for standard spindle rotation compatibility
• Minimum bore diameter of 0.16 inches for small-hole internal turning
• Maximum bore depth of 0.9 inches
• Bright finish coating — no additional coating to affect dimensional tolerances
• Compact 3/16-inch shank diameter fits standard small-bore toolholders

Compatibility

Designed for use with standard boring bar holders and quick-change tooling systems that accept a 3/16-inch shank diameter on CNC and manual turning equipment.

Installation Notes

Installation should be performed by a qualified machinist familiar with turning tool setup procedures. Ensure the machine spindle is fully stopped and locked out before mounting or adjusting the boring bar. Secure the shank in the toolholder to the recommended clamping depth — typically a minimum of 1.5 times the shank diameter — to minimize overhang and chatter. Verify tool centerline height relative to spindle centerline before taking the first cut.
