Accupro B060500R Corner Radius Boring Bar Carbide

Product Description

The ACCUPRO B060500R is a corner radius boring bar designed for precision internal boring operations in small-diameter applications. Machined from submicron-grade solid carbide with a bright, uncoated finish, this bar delivers consistent cutting performance and dimensional accuracy in tight bores. It features a right-hand cutting direction and supports a corner radius range of 0.003 to 0.005 inches, making it suitable for controlled edge geometry in finish-bore work. The 1/8-inch shank diameter and 1.5-inch overall length suit it to small-bore toolholders and high-speed spindle setups where rigidity in a compact profile is critical.

This boring bar is intended for use on CNC machining centers, lathes, and manual mills performing small-diameter internal boring passes. Its submicron carbide construction makes it appropriate for hard or abrasive materials where tool wear resistance is a priority. Machinists and tool-and-die professionals working on precision components, molds, or close-tolerance bores will find this bar suited to fine finishing passes rather than heavy stock removal. The bright, uncoated surface allows direct visual inspection of the cutting edge before and after use.

Key Features

• Submicron-grade solid carbide construction for enhanced wear resistance and edge retention
• Minimum bore diameter of 0.06 inches for work in very small internal features
• Maximum bore depth of 0.5 inches suitable for shallow precision bores
• Corner radius range of 0.003 to 0.005 inches for controlled edge geometry
• Right-hand cutting direction for standard spindle-direction setups
• Bright, uncoated finish for direct edge inspection and compatibility with a range of cutting fluids

Compatibility

Designed as an OEM-style replacement or direct-application boring bar for toolholders accepting a 1/8-inch shank diameter in small-bore internal turning and boring applications.

Installation Notes

Installation and use of this boring bar should be performed by qualified machinists familiar with CNC or manual turning and milling equipment. Ensure the machine spindle is fully stopped and the toolholder is properly torqued before beginning any boring pass. Verify shank seating depth and runout with a dial indicator before taking finish cuts. Follow the machine manufacturer and toolholder manufacturer guidelines for maximum clamping force to avoid micro-fracture of the carbide shank.
