Drill models have two or three blades. Knives can be straight or rounded. Ball knives are harder to make and sharpen, but they do better for both dry and wet ice. An ice drill with straight blades drills dry ice well, but when drilling wet ice, the effort required to turn the handle increases significantly, and an ice drill can get stuck in the hole. In practice, an ice drill with a diameter of 110-130 mm is suitable for most fisheries. The difference between two-handed ice drills and classic ones is that the upper handle of the ice drill is inclined 130 mm compared to the axis of the ice drill and the lower one is 150 mm. This arrangement of handles allows you to turn the ice drill with both hands at the same time, thus increasing the speed of drilling holes in the ice. Classic weight 100 mm - 2.27 kg, two-handed 100 mm - 2.17 kg.
