Accupro B3601600R Corner Radius Boring Bar Submicron Carbide

Product Description

The ACCUPRO B3601600R is a corner radius boring bar designed for precision internal boring operations on CNC lathes and manual turning centers. Machined from submicron-grade solid carbide, it delivers the rigidity and wear resistance needed for tight-tolerance bores. The bar features a right-hand cutting direction, a minimum bore diameter of 0.36 inches, and a maximum bore depth of 1.6 inches. With a corner radius range of 0.005 to 0.008 inches, it produces a controlled blend radius at the bottom of the bore. This tool is installed by machinists and CNC operators working in precision metalworking environments.

This boring bar is suited for internal finishing and semi-finishing passes in small-diameter bores. The 0.375-inch shank diameter and 3-inch overall length make it compatible with standard boring bar holders used on toolroom lathes and CNC turning machines. The bright finish (uncoated) substrate is appropriate for non-ferrous materials and some ferrous applications where coating-induced dimensional offset is undesirable. A right-hand cut designation means it feeds from right to left in standard lathe orientation.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Right-hand cut direction for standard lathe boring setups
• Corner radius range of 0.005 to 0.008 inches for controlled blend geometry at bore bottom
• Minimum bore diameter of 0.36 inches enables work in small internal diameters
• Maximum bore depth of 1.6 inches accommodates common shallow-to-medium bore depths
• Bright (uncoated) finish suitable for a range of workpiece materials

Compatibility

Designed as an OEM-style replacement and standard tooling option for 0.375-inch boring bar holders used on CNC and manual turning centers requiring right-hand internal boring capability.

Installation Notes

Install and remove tooling only after the machine spindle has come to a complete stop and the machine is in a locked-out, de-energized state per applicable shop safety procedures. Secure the shank fully within the boring bar holder to the manufacturer-specified grip length to minimize overhang and vibration. Verify tool runout and bore diameter on a test cut before committing to finish dimensions. Boring bar setup and operation should be performed by qualified machinists familiar with the specific turning machine being used.
