Scientific Cutting Tools B120250A Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS B120250A is a right-hand boring bar machined from submicron-grade solid carbide for precision internal boring operations. It accepts a minimum bore diameter of 0.120 inches and reaches a maximum bore depth of 0.25 inches, making it well-suited for tight, shallow bore applications where rigidity and dimensional accuracy are critical. The 3/16-inch shank diameter and 2-inch overall length give machinists a compact, controllable tool that fits standard boring bar holders used on CNC lathes and machining centers. Submicron carbide construction provides superior hardness and wear resistance compared to standard carbide grades, supporting extended tool life in precision production runs.

This boring bar is intended for small-diameter internal turning and boring work on CNC lathes, manual lathes, and machining centers in production or job-shop environments. Its compact geometry makes it a practical choice when machining small bores in ferrous and non-ferrous workpieces where a rigid, close-tolerance tool is required. Machinists working on watch components, medical parts, hydraulic fittings, and other precision small-bore applications will find the 0.120-inch minimum bore diameter useful for accessing tight internal features.

Key Features

• Submicron solid carbide construction for high hardness and extended wear resistance
• Minimum bore diameter of 0.120 inches for precision small-bore applications
• Maximum bore depth of 0.25 inches (1/4 inch) for shallow internal features
• Right-hand cutting direction for standard lathe and machining center setups
• 3/16-inch shank diameter fits common small boring bar holders
• Compact 2-inch overall length for improved rigidity in confined setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC lathes and machining centers equipped with 3/16-inch boring bar holder systems accepting right-hand solid carbide boring bars in the B12 series.

Installation Notes

Installation and use of this boring bar should be performed by a qualified machinist familiar with lathe and machining center tooling setup. Ensure the machine spindle is fully stopped and all motion is locked out before installing or removing the tool from the holder. Confirm the shank is fully seated and clamped securely in the boring bar holder before initiating a cut. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.
