Accupro ACC-BB180500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB180500 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes, turning centers, and manual boring equipment. Manufactured from submicron-grade carbide with a bright finish coating, it delivers consistent dimensional accuracy in tight-tolerance bore work. The right-hand cutting configuration suits standard spindle rotation setups. With a 0.18 inch minimum bore diameter and a 1/4 inch shank, this bar handles small-diameter finish boring where rigidity and runout control are critical. Overall length is 2.5 inches, and maximum bore depth reaches 0.5 inches.

This boring bar is suited for job shops, production machining environments, and tool rooms requiring reliable small-bore capability. It is appropriate for ferrous and non-ferrous materials where a rigid, wear-resistant carbide tool body is preferred over brazed or indexable alternatives. The submicron carbide grade supports higher cutting speeds and extended tool life compared to standard carbide grades, making it a practical choice for high-volume or precision finish operations.

Key Features

• Submicron solid carbide construction for improved wear resistance and cutting edge strength
• 0.18 inch minimum bore diameter for tight small-bore applications
• Right-hand cut configuration compatible with standard spindle rotation
• Bright finish coating for reduced friction and easier chip flow
• 1/4 inch shank diameter for common boring bar holders and quick-change tooling systems
• Compact 2.5 inch overall length reduces overhang and maximizes rigidity

Compatibility

Designed as an OEM-style replacement and direct-fit boring bar for 1/4 inch shank boring bar holders used in CNC lathes and manual turning equipment requiring a right-hand, small-diameter internal boring tool.

Installation Notes

Installation is performed by qualified machinists or tooling setup personnel. Secure the 1/4 inch shank in a compatible boring bar holder or quick-change toolpost, ensuring the shank is fully engaged to the minimum recommended grip depth. Power down and lock out the machine spindle before mounting or removing the bar. Do not exceed the maximum bore depth of 0.5 inches, as excessive overhang beyond designed parameters increases deflection and risk of tool breakage.
