I am in search of a drill to re-open holes too as I have made me a nice permanent shack out of a semi sleeper shack I use on red rock alot lately, trashed a lazer auger blade with my lithium lazer last year re-opening permy shack holes, and asked reeds sporting goods the same question on what to use to reopen holes, they said a chipper is designed for that so bought an 8" strikemaster chipper late in season but never got to try it out due to ice conditions and had to pull perm off.....now due to recall and no longer have lith lazer I am going with clam drill plate and new Milwaukee #2704-20 (1200 inlbs) of torque but wonder if it will turn the chipper drill?? don't wanna burn up my new drill, probably go with mora 8" if hole hopping, but would like to find one that is good for both, looking and wondering about k-drill myself anyone let me know....
