Accupro ACC-BB080300A Boring Bar 0.08 in Min Bore Carbide

Product Description

The ACCUPRO ACC-BB080300A is a solid carbide boring bar designed for small-diameter internal boring operations on CNC and manual lathes. Built from micrograin solid carbide with a TiAlN finish coating, it delivers the rigidity and wear resistance required for tight-tolerance bores in hard materials. The right-hand cutting direction suits standard lathe setups. With a minimum bore diameter of 0.08 inches, a maximum bore depth of 0.3 inches, a 1/8-inch shank diameter, and an overall length of 1.5 inches, this bar targets precision work where dimensional accuracy and surface finish are critical. Machinists and toolroom operators rely on tools like this for bore finishing and sizing in production and job-shop environments.

The ACC-BB080300A is suited for small-bore finishing and sizing applications in ferrous and non-ferrous materials. Its compact shank diameter and short overall length make it appropriate for micro-boring operations on Swiss-style lathes, turret lathes, and small CNC turning centers. The TiAlN coating improves performance at elevated cutting temperatures, extending tool life in dry or semi-dry machining conditions. This tool is a practical choice for shops requiring consistent bore geometry at diameters under 0.1 inches.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in small-bore applications
• TiAlN finish coating supports elevated cutting temperatures and extends tool life
• Minimum bore diameter of 0.08 inches enables precision micro-boring work
• Maximum bore depth of 0.3 inches suited for shallow internal features
• Right-hand cutting direction compatible with standard lathe rotation
• 1/8-inch shank diameter fits standard small-bore toolholders

Compatibility

Designed as a direct-fit boring bar for toolholders accepting a 1/8-inch shank diameter on CNC turning centers, Swiss-style lathes, and manual turret lathes requiring a right-hand cut boring tool.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and all axis motion is disabled before changing tooling. Secure the shank in a properly sized boring bar holder to the toolholder manufacturer's recommended clamping practice, avoiding excessive overhang beyond the maximum bore depth to minimize deflection. Verify tool runout before taking initial cuts.
