Scientific Cutting Tools BB105 Radial Relief Boring Bar

Product Description

The SCIENTIFIC CUTTING TOOLS BB105 is a radial relief boring bar machined from submicron-grade solid carbide for precision internal boring in tight-tolerance applications. It features a 0.105-inch minimum bore diameter and a 0.625-inch maximum bore depth, making it well suited for small-diameter bore work where rigidity and dimensional accuracy are critical. The 1/8-inch shank diameter and 1.5-inch overall length keep the tool compact and easy to seat in standard boring bar holders. The uncoated carbide substrate delivers consistent cutting geometry on a wide range of workpiece materials. Installation and setup are handled by machinists and CNC tooling technicians.

This boring bar is designed for right-hand cutting operations on CNC lathes, manual lathes, and boring mills where small minimum bore diameters are required. It is appropriate for production and job-shop environments targeting fine bore finishes in ferrous and non-ferrous materials. The radial relief geometry reduces tool pressure and chatter risk in shallow, small-diameter bores, making it practical for both single-part work and short-run production.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance in small-bore applications
• 0.105-inch minimum bore diameter for precision work in tight internal features
• 0.625-inch maximum bore depth supports a range of shallow internal bore depths
• Right-hand cutting direction for standard lathe and boring mill setup
• Radial relief geometry reduces cutting pressure and minimizes chatter
• Uncoated finish preserves sharp edge geometry on the carbide substrate

Compatibility

Designed for use in standard 1/8-inch boring bar holders on CNC and manual lathes, boring mills, and similar machine tool setups requiring small-diameter internal boring capability.

Installation Notes

This tool is installed and changed out by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the machine is powered down or placed in an e-stop state before changing tooling. Secure the shank firmly in the boring bar holder to the manufacturer-specified clamping method for the holder in use. Verify bore diameter and depth clearances against the workpiece setup before initiating a cut.
