Received this mag drill several days earlier than expected and put it to use right away. First thing I noticed was the lube tubing had a sharp kink it it got worse as the drill head was lowered to the work piece. Not that big a deal since I have some leftover 1/4\" tubing from another project. A second thing I noticed was the annular cutter pin did not have a spring to help push out the slug once the hole had been drilled. I didn't notice this at first, and when I placed the drill for the next hole the drill actually skipped due to the first slug still remaining in the bit. Once I figured that out, every other hole went smoothly. One complaint I noticed with others was the chuck adapter wouldn't fit into the Nitto quick disconnect. I didn't have this problem...the chuck adapter went in just fine and locked into place. All in all, very satisfied with the purchase right now...did what it should. You may need to tighten the three screws that secure the drill to the standard...mine were loose enough that once I inserted the three handles the drill's weight would cause the head to lower itself. I haven't tried the lube reservoir yet, so can't comment on that.
