Kovac Ice Master Nils Ice-Auger Adapter is an affordable two-piece conversion kit that turns your power drill and Nils hand auger into a power auger. The adapter consists of the exclusive retainer disk and adapting pin that protects the auger from going to the bottom if it disengages from the drill chuck. It also takes the weight of the auger off the chuck, putting it on the handle to protect the chuck from damage. It can also help your auger blades last longer. Works with Nils hand augers.
