Done a lot of tube notching in the past using a lathe. Use an end mill held in the chuck and a tube vice mounted on the toolpost, works a treat.
I don't have a tube holder for the toolpost on my lathe at the mo and I haven't had any suitable lumps of steel to make one from, so I use
a carbide cutter in the die grinder, which does the job in seconds anyway.

I've done all mine in a cheap drill press with a rotating bed and a vice. You do need expensive starrette typw hole saws and you will even take
the teeth off these eventually.
Aldi has a good drill press for £29.99 at the moment, 500W and lots of speeds, better than my old Makro one and £10 cheaper.

right then, it does tilt, but not very well! I got a nice adjustable vice from machine mart, and a set of holesaws, and set about some right angle
ones. I think tilting it would make it snatch too much, without the extra bearing of the notcher. Not bad at all though!

Joel,
Use cutting oil and light pressure on the drill press, if you don't have cutting oil use 3in1. as long as you don't press too hard and let
the saw cut it should work fine. It is also worth making sure that the drill bed is not flexing, the cheap ones do. when I was cutting holes out of
3mm wall tube I set up the bed so it was supported at the opposite side from the pillar with offcuts of tube and plate.
Best of luck

i knew it needed oil, but only had wd40! not quite the same need to get some sharpish  the bed does flex a little, but i can brace it

won't work and make a tube-clamping vice and off we go!

If you have a lathe, you can make a tube clamp to fit on the tool post. This can then be rotated to whatever angle you need. Use a milling cutter in
the chuck. A friend of mine has done this very successfully and for very little cost.
