Abstract
Disclosed is a device for boring holes in ice having a vertical boring position and a horizontal carrying position. The device is comprised of a drive unit with an output, a rotatable shank portion and auger portion coupled to the output. A non-driven grasping portion is connected to the drive unit and configured such that the device has a balance point at the grasping portion whereby the device may be carried in a balanced horizontal position with one hand. In a preferred embodiment a hollow cylindrical portion with a flange attaches to the drive unit and the shank portion extends through the cylindrical portion and is coupled to the out in the cylindrical portion. The grasping portion may either be the cylindrical portion or a separate bar portion attached to the cylindrical portions.
