Faunsdale, AL | Are you sure the travel on the rack is limited to 2” or is the annular cutter only capable of cutting 2” of SOLID material?
I’m no expert on them but I think the travel in the rack is going to be plenty to drill that tubing in one setup. Furthermore I think the annular cutter that really makes a mag drill so nice to use would handle cutting through two 3/8 thick walls just fine. AS LONG AS YOU GET THE SLUG FROM THE FIRST CUT OUT OF THE WAY BEFORE YOU START THROUGH THE OTHER SIDE.
You won’t have the problem I ran into when drilling through two plates that were lapped on top of each other. First cut was fine but I had to extract the slug before starting the second cut. It was stuck to the teeth of the cutter and spinning with it so the cutter wouldn’t bite. That out of the way, I started drilling on through the second thickness and found that I didn’t have them clamped tightly enough so the drill pushed them apart and put cutter in a bind and snapped it immediately.
I think it’ll work fine with an annular cutter or if not just get a good bit and a Jacobs type chuck for the mag drill and go to town. 3/8 wall should hold the mag base well enough that you won’t lift it unless you get ham fisted on the feed. Thin sheet metal won’t hold the magnet as well.
You may have to add a stand-off of a scrap piece of tubing to have room for the drill bit, the chuck and the adapter to go into the 3/4”?? hole in the spindle. That would have to be clamped to the piece you’re drilling very solidly because even though the drill bit may feel like it’s cutting through butter, you’ll be pushing it pretty hard as you feed it. Clamp it all tight, use some good drilling fluid and you will probably do it all with one bit. Fail to clamp it tight and you’ll snap the bit in the process of learning that lesson.

Magdrill that is advertised 2" cut depth
