A hexagonal drill rod, as the name suggests, features a hexagonal cross-section rather than the conventional circular one found in standard drill rods. This design alteration is not merely aesthetic; it serves a functional purpose that significantly enhances performance. The hexagonal configuration provides greater surface area, which in turn increases the contact area between the rod and the drilling machine. This results in better torque transfer, reducing slippage and enhancing overall drilling stability.

The shank's geometry is equally significant. It often features a Morse taper, a standard system, which allows for secure and quick attachment to the drill rod or chuck.
