Accupro ACC-HB3602000 Helical Boring Bar Solid Carbide

Product Description

The ACCUPRO ACC-HB3602000 is a helical boring bar machined from submicron-grade solid carbide and designed for precision internal boring operations on CNC and manual lathes. It accepts a minimum bore diameter of 0.36 inches and reaches a maximum bore depth of 2 inches, making it well suited for tight, shallow bores where rigidity and surface finish are critical. The 3/8-inch shank diameter and 4-inch overall length provide a compact, balanced profile. A bright finish coating is applied to the carbide blank. Right-hand cutting direction is standard. Machinists, toolroom operators, and CNC programmers working in precision shops select this bar for its consistent geometry and submicron carbide substrate, which supports tight tolerances and extended tool life.

This helical boring bar is intended for use in metalworking environments requiring accurate bore sizing in ferrous and non-ferrous materials. It fits standard 3/8-inch bore bar holders and quick-change tooling systems commonly found on CNC turning centers and manual engine lathes. Typical applications include finishing bores in fixtures, workholding components, hydraulic bodies, and machined housings where concentricity and surface finish are priorities. The helical flute geometry assists with chip evacuation during deep-reach passes within its 2-inch depth capacity.

Key Features

• Minimum bore diameter of 0.36 inches for tight-bore applications
• Maximum bore depth of 2 inches suits shallow-to-mid-depth internal operations
• Right-hand cutting direction compatible with standard lathe rotation
• 3/8-inch shank diameter fits common bore bar holders and quick-change systems
• Bright finish coating on carbide blank

Compatibility

Designed for use in standard 3/8-inch shank boring bar holders on CNC turning centers and manual lathes. No specific OEM machine or tooling system compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the lathe is powered down before mounting or removing the boring bar. Clamp the 3/8-inch shank securely in the tool holder with adequate overhang minimized to reduce chatter. Verify cutting direction and tool offset registration before initiating the first pass.
