Yes, with a good little tap. Use a soft mallet.
Have you tried mounting the vise to the bed of the press (using Tee bolts)? May have to shim if necessary due to the stroke of the press. I keep plywood scraps next to my press for just that shimming purpose. Good Luck
I'd say about 40lbs
Every component is made of steel. the table is thick. I've only drilled through solid aluminum so far, but I think it would handle steel tubing just fine. Use a lubricant and good bits and drill slowly.
Exactly 27 inches fully assembled according to my measuring tape.
No I had to order it by mail. But it came quickly and was easy to assemble. Super sturdy drill
You have a 10" working area. I don't see why not. I'd put a block of 2x6 scrap wood under whatever you're drilling through so your hole saw bit doesn't hit the table when you're through it. If you're drilling through something large, like maybe a door, I'd recommend using a cordless hand drill rather than a drill press.
Better than some I checked but keep in mind it's a hobbies press. Center punch and use a center drill is the norm
measures 7.5X7.5 9"from chuck tip to fully lowered base
