Scientific Cutting Tools B160900A Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS B160900A is a right-hand boring bar machined from submicron-grade solid carbide. It is designed for internal boring operations requiring tight tolerances and small bore diameters. With a minimum bore diameter of 0.160 inches and a maximum bore depth of 0.900 inches, this bar handles precision small-bore work in CNC lathes and machining centers. The 3/16-inch shank diameter and 2-inch overall length make it well-suited for short-reach, high-accuracy applications. Submicron carbide grade provides superior hardness and edge retention compared to standard carbide, making it appropriate for close-tolerance finishing passes in production environments.

This boring bar is used in metal-cutting operations where small internal diameters must be held to precise dimensions. Typical applications include small-bore finishing on turned components, instrument parts, hydraulic valve bodies, and similar workpieces requiring consistent surface finish and dimensional accuracy. It is installed and operated by machinists and CNC operators working with lathes, turning centers, or milling machines equipped with appropriate boring bar holders. The B160900A belongs to the B16 series from SCIENTIFIC CUTTING TOOLS.

Key Features

• Submicron solid carbide construction for superior hardness and edge retention
• Right-hand cutting direction for standard lathe and boring head setups
• Minimum bore diameter of 0.160 inches enables small-bore internal machining
• Maximum bore depth of 0.900 inches suits short-reach precision applications
• 3/16-inch shank diameter fits standard small-bore toolholders
• 2-inch overall length provides rigid, low-deflection setup

Compatibility

Designed as an OEM-style replacement and standard tooling option for small-bore internal turning operations using toolholders and boring bar sleeves accepting a 3/16-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Secure the shank firmly in a compatible boring bar holder or sleeve, ensuring proper overhang is minimized to reduce deflection. Power down and lock out the machine spindle before inserting or adjusting the boring bar. Follow shop safety procedures and applicable OSHA machine guarding standards when handling carbide tooling.
