Accupro ACC-BBL360500 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BBL360500 is a left-hand cut 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 the rigidity and edge retention required for tight-tolerance bores in ferrous and non-ferrous materials. The bar features a 0.36-inch minimum bore diameter and accepts a maximum bore depth of 0.5 inches, making it well suited for shallow, precise bores where dimensional accuracy is critical. The 3/8-inch shank diameter and 2.5-inch overall length keep the setup compact and minimize overhang-related deflection during the cut.

This boring bar is intended for use in precision machining environments including job shops, production turning cells, and toolroom applications. It is a left-hand cut tool, meaning it is oriented for specific spindle rotation and tool post positioning — confirm your setup requirements before ordering. The bright, uncoated finish makes it a practical choice for non-ferrous materials such as aluminum and brass where coatings can cause adhesion issues, while the submicron carbide grade supports consistent performance across a range of steels and alloys at appropriate cutting parameters.

Key Features

• Submicron solid carbide construction for high rigidity and edge retention
• Left-hand cutting direction for specific turning orientations
• 0.36-inch minimum bore diameter for small, tight-tolerance internal features
• 0.5-inch maximum bore depth keeps setup compact and reduces deflection
• Bright finish suitable for non-ferrous and general-purpose boring applications
• 3/8-inch shank diameter fits standard boring bar holders and quick-change tooling systems

Compatibility

Designed for use in standard 3/8-inch boring bar holders on CNC lathes, manual lathes, and turning centers requiring left-hand cut internal boring tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before mounting or changing tooling. Ensure the shank is fully seated and clamped securely in the boring bar holder to the manufacturer-specified clamping procedure for your toolholder. Confirm spindle rotation direction and tool orientation are correct for left-hand cut tooling before initiating a cut.
