Accupro ACC-BB110700 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB110700 is a solid carbide boring bar designed for precision internal boring operations on lathes and turning centers. Manufactured from submicron-grade carbide with a bright finish, it delivers consistent dimensional accuracy in tight-bore applications. The bar accepts a minimum bore diameter of 0.11 inches and reaches a maximum bore depth of 0.7 inches, making it well suited for small, deep-relative-to-diameter features. The 1/8-inch shank diameter keeps the tool compact and rigid. Right-hand cutting geometry is standard. Machinists and tool-and-die professionals install this bar where fine surface finish and close tolerances are required in small-diameter bores.

This boring bar is used in precision machining environments including job shops, production turning cells, and tool-and-die operations. It is appropriate for boring small through-holes and blind bores in ferrous and non-ferrous workpieces where a minimum bore diameter of 0.11 inches and a reach of up to 0.7 inches are needed. The submicron carbide grade supports higher cutting speeds and longer tool life compared to standard carbide grades, particularly in interrupted or finish-boring passes on hardened or abrasive materials.

Key Features

• Submicron solid carbide construction for extended tool life and dimensional stability
• Minimum bore diameter of 0.11 inches suits very small internal features
• Maximum bore depth of 0.7 inches provides adequate reach for short blind and through bores
• Right-hand cutting direction for standard lathe and turning center setups
• Bright finish coating reduces friction and aids chip evacuation
• 1/8-inch shank diameter fits compact toolholders and small-bore applications

Compatibility

Designed as a standard right-hand boring bar for use in toolholders and boring bar holders accepting a 1/8-inch shank diameter on manual or CNC lathes and turning centers.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practice. Secure the shank fully within the toolholder, ensuring adequate engagement length to minimize overhang and chatter. Power down and lock out the spindle before installing or removing the tool. Follow the machine manufacturer and toolholder manufacturer guidelines for clamping torque and runout verification before cutting.
