This money- and time-saving two-piece conversion kit creates a power auger by connecting your power drill and hand auger. Compatible with any 1/2" drill chuck, the exclusive retainer disk protects the chuck from damage by transferring weight from the chuck to the handle. The retainer disk also prevents the auger from deep-sixing if it disengages from the chuck. This system extends the life of auger blades, too. Easily installs with the included adapting pin. Compatible with StrikeMaster Laser, StrikeMaster Mora, Eskimo and Normark hand augers. It also works with adjustable-pin and threaded-type augers from 4"-8".
