Accupro B060200R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B060200R is a corner radius boring bar designed for precision internal boring operations in small-diameter applications. Machined from submicron solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance work in hardened or abrasive materials. The bar has a minimum bore diameter of 0.06 inches, a maximum bore depth of 0.2 inches (13/64 inches), and a corner radius range of 0.003 to 0.005 inches. The bright finish reduces friction and assists with chip evacuation. At 0.0625 pounds, this is a compact tooling component built for CNC and manual boring applications where dimensional accuracy is critical.

This boring bar is suited for small-bore finishing and semi-finishing operations in machine shops, tool rooms, and production environments. Its right-hand cutting direction makes it compatible with standard spindle rotation on most lathes and boring mills. The 1/8-inch shank diameter and 1.5-inch overall length fit compact toolholders and small-bore heads commonly used in precision turning centers and manual lathes handling fine detail work. Machinists and CNC operators working with tight interior profiles and corner geometry control will find this bar applicable to their operations.

Key Features

• Submicron solid carbide construction for high rigidity and wear resistance in demanding materials
• Corner radius range of 0.003 to 0.005 inches for controlled interior corner geometry
• Minimum bore diameter of 0.06 inches enables work in very small internal features
• Bright finish coating reduces friction and aids chip flow
• Right-hand cutting direction compatible with standard spindle rotation
• Compact 1/8-inch shank diameter suits small-bore toolholders and precision setups

Compatibility

Designed for use in toolholders accepting a 1/8-inch shank boring bar. Confirm toolholder bore size and minimum bore clearance before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with boring bar setup and small-diameter tooling. Ensure the machine spindle is fully stopped and the machine is powered down before inserting or removing the bar from the toolholder. Verify shank seating depth and overhang length to minimize deflection, which is critical at this diameter and bore depth. Do not exceed the rated maximum bore depth of 0.2 inches to avoid tool deflection or breakage.
