Accupro ACC-BBL2001000 Boring Bar Left Hand Solid Carbide

Product Description

The ACCUPRO ACC-BBL2001000 is a left-hand cut solid carbide boring bar engineered for precision internal boring operations on CNC lathes and manual turning centers. Manufactured from submicron-grade solid carbide with a bright finish coating, this bar delivers the rigidity and wear resistance required for tight-tolerance bore work. It accepts a minimum bore diameter of 0.2 inches and reaches a maximum bore depth of 1 inch, making it well-suited for small-diameter, shallow-bore applications. With a 0.25-inch shank diameter and an overall length of 2.5 inches, it fits standard tool holders used in light to medium turning setups.

This boring bar is intended for use in machine shop environments where left-hand cutting geometry is required, typically for back-boring operations or setups where conventional right-hand tooling cannot reach the target feature. It is appropriate for ferrous and non-ferrous materials where submicron carbide grade provides the cutting-edge integrity needed to hold dimensional tolerances. Machinists and CNC operators working on small-bore components will find this bar compatible with standard quarter-inch boring bar tool holders and quick-change turrets.

Key Features

• Left-hand cutting direction for back-boring and specialized turning setups
• Submicron-grade solid carbide construction for extended edge life and rigidity
• Bright finish coating with no added coating thickness to affect dimensional accuracy
• 0.2 inch minimum bore diameter for small-diameter internal features
• 1 inch maximum bore depth suits shallow-bore applications
• 0.25 inch shank diameter fits standard boring bar holders and quick-change turrets

Compatibility

Designed for use in standard 0.25 inch boring bar tool holders on CNC and manual lathes requiring left-hand cut geometry for internal boring operations.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Power down and lock out the machine before mounting or removing tooling. Ensure the shank is fully seated and clamped to the minimum insertion depth recommended by the tool holder manufacturer to prevent deflection and chatter. Verify cutting direction geometry matches the intended operation before initiating a cut.
