Accupro B160900R Boring Bar Submicron Solid Carbide

Product Description

The ACCUPRO B160900R is a solid carbide boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Built from submicron-grade carbide, this right-hand cutting tool holds tight tolerances in small-bore applications where rigidity and wear resistance are critical. With a minimum bore diameter of 0.1600 inches and a maximum bore depth of 0.9000 inches, it suits close-tolerance work in hard and abrasive materials. The 3/16-inch shank diameter and 2-inch overall length (OAL) make it a compact, purpose-built tool for machinists working in tight bore geometries.

This boring bar is suited for production and job-shop environments where small-diameter internal features require precise diameter control and a clean finish. It is appropriate for use in materials such as hardened steels, stainless alloys, cast iron, and other difficult-to-machine workpieces where submicron carbide provides a measurable edge life advantage over standard carbide grades. Machinists and tool-and-die professionals working on fixture components, hydraulic bodies, and precision housings are the primary users of this tool type.

Key Features

• Submicron solid carbide construction for extended tool life in hard and abrasive materials
• Right-hand cutting direction for standard lathe and boring mill setups
• 0.1600 inch minimum bore diameter enables work in very small internal features
• 0.9000 inch maximum bore depth supports deep-relative-to-diameter small-bore applications
• 3/16 inch shank diameter fits standard small-bore toolholders and quick-change systems
• 2 inch OAL provides a compact footprint for close-clearance setups

Compatibility

Designed as an OEM-style replacement and standard fit for toolholders accepting a 3/16 inch round shank boring bar in CNC lathe, manual lathe, and boring mill applications.

Installation Notes

This boring bar is installed and set by a machinist or toolroom technician. Before changing or setting tools, ensure the machine spindle is at a full stop and all motion is locked out per your facility lockout/tagout procedure. Secure the shank firmly in the toolholder with appropriate clamping torque per the toolholder manufacturer's specification. Inspect the cutting edge under magnification before use; carbide is brittle and edge chips not visible to the naked eye will affect bore quality.
