Accupro B3601150R Corner Radius Boring Bar Solid Carbide

Product Description

The ACCUPRO B3601150R is a corner radius boring bar machined from submicron-grade solid carbide for use in precision internal boring operations. It cuts in a right-hand direction with a minimum bore diameter of 0.36 inches and a maximum bore depth of 1.15 inches. The shank diameter is 3/8 inches and the overall length is 2.5 inches. Corner radius range runs from 0.0050 to 0.0080 inches, allowing the tool to blend a controlled radius at the bottom corner of a bore. A bright finish coating is applied to the carbide body. This bar is selected by machinists and toolroom personnel who require tight-tolerance internal features in hard or abrasive workpiece materials.

This boring bar is suited for use on CNC lathes, manual lathes, and boring mills where a small-diameter internal bore with a defined corner radius is required. The compact geometry and submicron carbide grade make it appropriate for finishing passes in hardened steels, stainless alloys, cast iron, and similar materials. It fits standard 3/8-inch boring bar holders and tool blocks commonly found in production and job-shop environments.

Key Features

• Submicron solid carbide construction for extended tool life in hard and abrasive materials
• Right-hand cutting direction for standard CNC and manual lathe setups
• Minimum bore diameter of 0.36 inches allows entry into small internal features
• Corner radius range of 0.0050 to 0.0080 inches for controlled blend at bore floor
• Bright finish coating on carbide body
• 3/8-inch shank diameter fits common boring bar holders

Compatibility

Designed as a direct-fit replacement or new installation in any 3/8-inch boring bar holder or tool block accepting solid carbide boring bars of this shank diameter and overall length.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank firmly in the holder to the manufacturer-specified clamping torque for the holder being used, as under-clamping can cause deflection and chatter. Confirm bore depth and diameter against part print before committing to finishing passes.
