|Finding the right-sized drill is never an easy task. Scrounge one up too small, and it'll be lacking in power; scrounge one up too big, and it'll be a real doozy to handle. Trying to swing this drill—taken from the heavy-duty mining excavator—in particular, is a nigh impossible task for the uninitiated. But a clever craftsman constructed the consummate solution. By attaching this drill to a lengthy handle, what was once a powerful yet extremely unwieldy doohickey now functions as a potent spear that also happens to be relatively easy to swing.|
