Accupro B120600R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B120600R is a corner radius boring bar designed for precision internal turning operations on CNC lathes and boring machines. Machined from submicron solid carbide, this right-hand cut tool delivers the rigidity and wear resistance needed for tight-tolerance bore finishing. It handles minimum bore diameters starting at 0.12 inches and reaches a maximum bore depth of 0.6 inches. The 3/16-inch shank diameter and 2-inch overall length make it suited for small-bore applications where clearance and tool overhang are critical. A bright finish coating is standard. This tool is used by machinists and toolroom professionals working in close-tolerance environments.

The B120600R is applied in small-bore internal turning and finishing operations, particularly where a controlled corner radius is required at the base of the bore. A corner radius range of 0.005 to 0.008 inches helps reduce stress concentrations in finished bores. Typical applications include precision component machining in aerospace, medical, and general metalworking environments. The right-hand cutting direction suits conventional lathe and boring mill setups. This bar is sold individually and is appropriate for shops requiring a dedicated tool for repeatable small-bore finishing passes.

Key Features

• Submicron solid carbide construction for extended tool life in abrasive and hard materials
• Corner radius range of 0.005 to 0.008 inches for controlled edge geometry at bore base
• Minimum bore diameter of 0.12 inches for small-bore internal turning
• Maximum bore depth of 0.6 inches
• 3/16-inch shank diameter with 2-inch overall length for compact tooling setups
• Bright finish coating, right-hand cut configuration

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC lathes, manual lathes, and boring mills accepting a 3/16-inch shank boring bar in right-hand cut orientation.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. The boring bar should be secured in a compatible tool holder or boring bar holder rated for the 3/16-inch shank diameter, ensuring minimal overhang to reduce vibration. The machine spindle must be stopped and all motion halted before mounting or adjusting the tool. Confirm correct cutting direction and tool height before commencing a bore pass.
