Scientific Cutting Tools BB122 Radial Relief Boring Bar

Product Description

The SCIENTIFIC CUTTING TOOLS BB122 is a radial relief boring bar designed for precision internal boring operations on small-diameter features. Machined from submicron-grade solid carbide, it delivers the rigidity and edge retention required for tight-tolerance bores. The right-hand cutting configuration suits standard CNC and manual lathe setups. With a minimum bore diameter of 0.12 inches and a 1/8-inch shank diameter, this bar is built for small-bore applications where tool deflection and wear must be minimized. The uncoated carbide finish allows for direct inspection of edge condition and suits a wide range of workpiece materials.

The BB122 is suited for small-bore internal turning in production and toolroom environments. Its 0.25-inch maximum bore depth and compact 1.5-inch overall length make it well-matched to Swiss-style lathes, CNC turning centers, and manual lathes handling miniature components. Machinists working on precision parts in aerospace, medical device, and general machining applications will find this bar useful where access to tight bores is required. The 1/8-inch shank fits standard small-bore toolholding systems commonly found in those setups.

Key Features

• Submicron solid carbide construction for superior rigidity and edge retention
• Radial relief geometry optimized for internal boring operations
• Right-hand cut for standard lathe and turning center configurations
• Minimum bore diameter of 0.12 inches for small-feature access
• Uncoated finish for consistent cutting performance across varied materials
• Compact 1.5-inch overall length suits confined tooling envelopes

Compatibility

Designed as an OEM-style replacement or direct tooling solution for 1/8-inch shank boring bar holders used in small-bore internal turning applications on CNC and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-bore toolholding systems. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bar. Secure the 1/8-inch shank firmly in the toolholder to the holder manufacturer's specified clamping procedure to prevent tool pull-out during cutting. Verify bore diameter clearance before engaging the cut to avoid contact between the bar body and the workpiece bore wall.
