Accupro ACC-BB080300 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB080300 is a submicron solid carbide boring bar designed for precision internal boring operations on small-diameter features. With a minimum bore diameter of 0.08 inches and a maximum bore depth of 0.3 inches, this bar is built for tight-tolerance work in CNC turning centers and manual lathes. The bright finish coating reduces friction and aids chip flow. The 1/8-inch shank diameter and 1.5-inch overall length make it well-suited for compact tooling setups where rigidity and dimensional accuracy are critical. Machinists and toolroom operators working on small-bore components will find this bar a direct fit for high-precision finishing and sizing passes.

This boring bar is intended for use in metalworking applications requiring precise internal diameter control at small bore sizes. It is a right-hand cut tool, meaning it advances from right to left in standard lathe orientation. Typical applications include finishing bores in aluminum, steel, and similar machinable metals where tight tolerances and fine surface finishes are required. The submicron carbide grade provides enhanced wear resistance compared to standard carbide grades, making it appropriate for production runs as well as one-off precision work.

Key Features

• Submicron solid carbide construction for improved wear resistance and edge retention
• Minimum bore diameter of 0.08 inches supports very small internal features
• Maximum bore depth of 0.3 inches suitable for shallow precision bores
• Right-hand cutting direction for standard lathe and CNC turning center use
• Bright finish coating reduces friction and promotes chip evacuation
• Compact 1.5-inch overall length with 1/8-inch shank for tight tooling clearances

Compatibility

Designed as an OEM-style precision boring bar compatible with tool holders and boring head systems accepting a 1/8-inch round shank.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with CNC or manual lathe tooling. Ensure the machine spindle is fully stopped and the tool turret or holder is locked before mounting or removing the bar. Secure the shank firmly in the tool holder to the required clamping torque specified by the holder manufacturer, not by this bar. Verify runout with a dial indicator before taking the first cut to confirm concentricity and protect the carbide edge.
