Here's what I think Wally is talking about. The model 11-280. Delta also made a radial drill press model 15-126 but you don't want to go there just yet.What about used? I have an older Rockwell radial drill press that I have owned since the early 70's and it has served me well for all these years. Not sure if it would be considered bench top or not. I threw away the sheet metal stand a long time ago and built a wooden stand with storage slide outs underneath to better utilize space.
Just look around the shop clutter. This is a 1968 version. Later ones had different cosmetics but mechanically the same.
