hey guys , I did put my earth auger on my drill, the output shaft of the motor is a stub about 3 or so inches long with a hole sideways in it, and my auger separated at the center from the handle . I did have to cut a small part off the length at the to of the auger to help fit . the adapter is a heavy tube that I drilled each end to fit its about 16 inchs long....now aafter the fact I wish I would added about 10 more inches on length, slab is right its a bear and drills well
