The Foro 1650 Drill (previously referred to as the Intermediate Depth Drill or IDD) is the next generation of the Danish Hans-Tausen Drill and Danish Deep Drill, with the capability of producing 2-meter long cores. The Foro 1650 Drill is sufficiently portable for coring at a wide variety of sites, and capable of retrieving 98 mm diameter core from the surface down to 1600 meters depth in two field seasons.
In addition to the drill itself, the Foro 1650 Drill system includes the following ancillary items:
- Core Processing System: core barrel puller, trays, vacuum, saw, and tables
- Centrifuge to recover the drill fluid from the chips created by drilling the core
- Drill fluid handling system
- Vacuums to clean the drill cable and the core
- Pilot hole system
- A 4.9 m (16 ft) x 19.5 m (64 ft) x 2.8 m (9 ft) un-insulated Weatherport for housing the drilling and core processing operations
The Foro 1650 Drill is designed and constructed to be transportable by Twin Otter or Bell 212 (or similar) helicopter. For field projects lasting more than one season, most equipment is left onsite to "winter-over". To drill to 1500 meters depth in two field seasons, a 10 person field-team for 24-hour per day drilling and core handling operations is required.

The drill head of the Intermediate Depth Drill with a core inside the drill barrel. The rotating drill head contains three razor sharp cutters that shave out an annulus of ice, which the drill then slides down into. As the drill slides down into the annulus it slides over the core, which is 98 mm (3.86 inches) in diameter. When a cable pulls up the drill, three cams grab the core and break it free. After the drill is pulled back to the surface it is lowered from a vertical to horizontal orientation so that the ice core can be removed from the drill barrel. Credit: T.J. Fudge

The 2-meter long sections of core are then cut into 1-meter long sections so that they fit into the standard-sized insulated shipping container (ISC) boxes used by the US ice-coring community to transport ice cores. A dry-cut circular saw is used to make the cuts. Credit: Murat Aydin
