Adapter kit with 155mm EZ Cut blades for Rapala UR EVO. Custom battery drill. Fits UR Rapala EVO Steel and former UR Rapala Green. Plate that prevents the spiral from disappearing into the hole if you lose it from the drill. Fits up to 155mm drill diameter. (does not fit UR Steel Foldable models) EZ CUT are straight knives with composite guides that make the drill go much easier through the ice. The drill makes several rounds to get through, but drills more easily. Serrated egg keeps the knives sharp longer, even when drilling in ice containing sand.
