Scientific Cutting Tools B160250A Boring Bar Solid Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS B160250A is a right-hand boring bar machined from submicron-grade solid carbide, designed for precision internal boring operations in small-diameter applications. It accepts a minimum bore diameter of 0.160 inches with a maximum bore depth of 0.25 inches, making it well suited for tight-tolerance work in hardened or abrasive materials. The 3/16-inch shank diameter and 2-inch overall length give it a compact, rigid profile that minimizes deflection during cut. Machinists working on CNC lathes or manual turning centers will find this bar reliable for finishing passes where bore geometry and surface finish are critical.

This boring bar is intended for small-bore internal turning applications in precision machining environments, including production shops, toolrooms, and job shops. It performs in materials ranging from aluminum alloys to hardened steels and cast iron where a submicron carbide substrate provides wear resistance and edge retention. The Series B16 designation places it within a family of small-shank boring tools suited for Swiss-type, turret lathe, and small CNC turning setups where bore access is restricted and tool overhang must be minimized.

Key Features

• Submicron solid carbide construction for extended edge life in abrasive and hard materials
• Minimum bore diameter of 0.160 inches enables work in very small internal features
• Maximum bore depth of 0.25 inches suitable for shallow precision bores
• Right-hand cutting direction for standard lathe and turning center setups
• 3/16-inch shank diameter fits common small-bore tool holders and turret stations
• 2-inch overall length provides a compact, low-overhang profile for rigidity

Compatibility

Designed as an OEM-style precision boring bar for use in tool holders accepting a 3/16-inch round shank, commonly found on small CNC turning centers, Swiss-type lathes, and turret lathes configured for small-bore internal operations.

Installation Notes

A qualified machinist should install this boring bar in a clean, properly sized tool holder bore and secure it with appropriate clamping torque per the tool holder manufacturer guidelines. Ensure all machine power is locked out and the spindle is fully stopped before changing tooling. Carbide is brittle and should not be used as a pry or lever during setup. Verify shank runout after seating to maintain bore diameter accuracy.
