Accupro ACC-BB1801500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB1801500 is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Manufactured from submicron-grade solid carbide with a bright finish coating, it delivers the rigidity and wear resistance needed for tight-tolerance bore work. The bar has a minimum bore diameter of 0.18 inches and a maximum bore depth of 1.5 inches, with a 0.25 inch shank diameter and an overall length of 2.5 inches. The right-hand cutting direction makes it compatible with standard spindle rotation on most turning setups. Machinists and toolroom professionals working on small-diameter internal features will find this bar suited to ferrous and non-ferrous applications alike.

This boring bar is intended for use in close-tolerance finishing and semi-finishing passes on small bore diameters. Its compact overall length of 2.5 inches and 0.25 inch shank diameter make it well suited to gang-tool setups, turret lathes, and Swiss-style or sub-spindle configurations where clearance is limited. The submicron carbide grade supports consistent edge retention over extended run times, reducing the frequency of tool changes in production environments.

Key Features

• Submicron-grade solid carbide construction for superior edge retention and rigidity
• Minimum bore diameter of 0.18 inches supports small, tight-tolerance internal features
• Maximum bore depth of 1.5 inches suits typical shallow-to-medium bore applications
• Right-hand cutting direction for standard spindle rotation compatibility
• Bright finish coating reduces built-up edge on non-ferrous and light ferrous materials
• 0.25 inch shank diameter fits a wide range of standard boring bar holders and turret blocks

Compatibility

Designed as a direct-fit replacement or new installation for standard 0.25 inch boring bar holders used in CNC and manual turning applications requiring a right-hand, small-diameter internal boring tool.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a full stop and locked-out condition per facility lockout/tagout procedures. Secure the shank fully within the tool holder to the manufacturer-recommended minimum clamp engagement to prevent chatter or pullout. Inspect the cutting edge for chips or wear before each use. Follow shop-specific feeds, speeds, and depth-of-cut parameters for the workpiece material and machine capability.
