Accupro ACC-BB2901600 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB2901600 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and manual turning centers. Manufactured from submicron-grade solid carbide, this right-hand cut tool delivers a minimum bore diameter of 0.29 inches and a maximum bore depth of 1.6 inches. The bright finish coating reduces friction and helps resist built-up edge during cutting. With a 5/16-inch shank diameter and a 3-inch overall length, it fits standard boring bar holders on light to medium turning equipment. Machinists and tool room operators use this bar for precision bore finishing in ferrous and non-ferrous workpieces.

This boring bar is suited for production and tool room environments where tight bore tolerances are required. The submicron carbide grade provides a fine grain structure that supports sharp cutting edges and extended tool life in interrupted and continuous cuts. The right-hand cutting direction makes it compatible with conventional forward-running spindle setups. It is commonly installed in CNC and manual lathes performing internal grooving, counterboring, and finish boring passes on small-diameter bores.

Key Features

• Submicron solid carbide construction for sharp edge retention and long tool life
• Minimum bore diameter of 0.29 inches for small-bore applications
• Maximum bore depth of 1.6 inches suits a range of workpiece lengths
• Right-hand cut direction for standard forward-spindle operation
• Bright finish coating reduces friction and resists built-up edge
• 5/16-inch shank diameter fits standard light-duty boring bar holders

Compatibility

Designed as an OEM-style boring bar for use in CNC and manual lathes equipped with standard 5/16-inch boring bar holders capable of accommodating a 3-inch overall length tool.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the boring bar from its holder. Verify shank clamp torque per the machine tool manufacturer guidelines and confirm tool overhang does not exceed recommended length-to-diameter ratios to minimize chatter. Inspect the cutting edge for chips or wear before each use.
