Accupro ACC-BB2901100 Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO ACC-BB2901100 is a solid carbide boring bar engineered for precision internal boring operations on CNC lathes and manual turning centers. It features a submicron carbide grade that provides high wear resistance and edge stability under demanding cutting conditions. With a minimum bore diameter of 0.29 inches and a maximum bore depth of 1.1 inches, this bar is suited for small-diameter, tight-tolerance work. The right-hand cutting direction and bright finish complete the specification. Machinists and toolroom technicians install this type of tooling in production and job-shop environments where consistent bore geometry and surface finish are required.

This boring bar is applicable to a wide range of turning applications including finish boring, semi-finish boring, and light interrupted cuts in ferrous and non-ferrous materials. The 5/16 inch shank diameter and 2.5 inch overall length make it compatible with small-to-medium turret toolholders and boring bar holders typically found on bench lathes, gang-tool lathes, and compact CNC turning centers. It is well suited for precision component manufacturing in aerospace, medical, and general machining industries.

Key Features

• Submicron solid carbide construction for superior wear resistance and edge retention
• Minimum bore diameter of 0.29 inches for small-hole internal turning
• Maximum bore depth of 1.1 inches to handle typical small-part boring depths
• Right-hand cutting direction for standard lathe setup
• Bright finish coating with no additional surface treatment that could alter critical shank dimensions
• Compact 5/16 inch shank diameter fits standard small-bore toolholders

Compatibility

Designed as an OEM-style replacement and direct-fit boring bar for standard 5/16 inch boring bar holders and turret toolposts used in small-to-medium turning center applications.

Installation Notes

This boring bar is installed by a qualified machinist or toolroom technician. Before mounting, ensure the lathe or turning center is fully powered down and the turret is locked out per shop lockout/tagout procedures. Secure the shank firmly in a compatible toolholder to the appropriate clamping torque specified by the toolholder manufacturer. Do not exceed the maximum bore depth rating of 1.1 inches, as overhang beyond rated depth increases deflection and risk of tool breakage.
