odd question about drill presses - mound - 05-01-2017
I notice that on pretty much every drill press out there, the base is machined flat and shiny and includes a couple of large T-tracks, yet I don't think I've ever seen anything mounted to the base of a drill-press.
What are some things this is used for?

I thought they were there to lag the base to the concrete (or other) floor to prevent tipping.

+1, Except that mine is lagged to a mobile base that is much wider than the stock base.

The documentation for my press specifies mounting the base to a support surface through the holes "A" in the photo near the post. It doesn't say anything about the T-slots. I've always assumed they were mounting something I don't have on the base, like an auxiliary support for a large workpiece. I don't see why they couldn't also used to lag the base down instead of the holes "A", but I also wonder if they don't have some special purpose other than that.

I did some more research and found this from the American Machine Tool Company:
"The base of the drilling machine supports the entire machine and when bolted to the floor, provides for vibration-free operation and best machining accuracy. The top of the base is similar to a worktable and may be equipped with T-slots for mounting work too large for the table."

wow, I never knew. Thanks to the OP for posting the question and to Allan for solving the mystery (at least it was a mystery to some of us).
