I got some tools left behind after a woman died, that her husband had left behind 10 years ago when he died. Both were in their 80's. He made furniture, at least as a hobby. There was some nice furniture there that they were selling, that he made, that he and his wife had used for, I think, decades.
Two were a matching quarter inch drill and something I thought was a drill, but is labeled Black & Decker Model 586 Tapgun.
Now that I have the "tapgun" running, it only turns counter-clockwise and it seems like a normal, low speed 1/4 inch drill, but it has a 1 inch push-back spring on the shaft just behind the chuck and sometimes, like if I grab hold of the chuck, it seems to be moving forwards and backwards, "tapping" the work.
I've wanted a hammer drill since I saw they made them (because they make them), but I've never actually seen one run in hammer mode. Is this a pre-cursor, since it only seems to tap and not hammer, or is it just that this is B&D's name, and hammer drill is generic. Web searches find nothing for me.
Why does it only turn counter-clockwise? And what is this especially good for! I like it because it's old, but it really should do something. :)
(Both have matching steel cases and 3-prong plugs, and this one was broken. The trigger wouldn't pull in, but last night I fixed that (only needed lubrication, but I think I had to take it apart to reach the right spot))
