The HCD25-100 Underwater compact core drill is the most powerful and easily manageable handheld underwater core drill available. The HCD25-100 is extremely easy to use and will drill through any material. There is no need for a drill rig. However, the HCD25-100 fits in a standard drill rig with a 60 mm flange for more demanding jobs.

The core drill has a built-in hydraulic torque limiter, ensuring max torque and no kickback if the core bit jams.
