HDD can operate with diameters up to what size?

Horizontal Directional Drilling uses a guided bore to install conduit underground, and the bore size is limited by the equipment’s thrust, steering control, and mud-management system. With standard HDD equipment used in typical telecom installations, you can reliably drill bores up to about two feet in diameter. That practical upper limit means the largest bore size commonly achievable by HDD is around two feet, so that choice best represents what HDD can operate with in ordinary practice. Larger bores would require specialized, more costly rigs or alternate methods, which is why they’re not considered the standard maximum. Smaller diameters are indeed possible, but they don’t represent the maximum capability.
