Winkie Drill
The Winkie Drill is an agile commercially-available rock coring unit designed by Minex and purchased by IDDO for subglacial rock coring. IDDO has adapted the base unit to allow for ice augering and ice coring applications in the polar regions. This drill is one of two rock coring drills in the IDDO inventory (see also ASIG Drill). Using standard AW34 drill rod, the system has a depth capability of 120 meters in blue ice. The drill uses traditional forced fluid circulation during coring, as is common in rock coring applications. All components of the Winkie Drill system can fit in a Twin Otter or similar-sized aircraft.
