re: Add a Table Top Drill Press?

One example that comes to mind with owning two drill presses is if you do special operations that requires a set up like mortising. You could have one drill press for drilling and boring holes and have the other set up with a mortising attachment to do just mortises.
If you don’t do a lot of special set ups and only use your current drill press to drill and bore holes, the maybe a second table top isn’t necessary. Unless of course, the floor space is more valuable to you than the workbench space, then you can get the table top and part ways with the floor standing. But personally speaking, I used to own a bench top but now own a floor standing and wouldn’t go back
