Tool porn

Hey lufguss, could you help me choose decent tools for metalworking ?
Some important details :

• They will mostly be used for mounting metal fenders, and some hacks/bodges here and there.
  
• I’m an apartment dweller who needs to move fairly often due to work. Compacity is thus my number one priority
  
• I’m broke atm, so if anything should definitely be downgraded or bought second hand, please let me know. I have the bad tendency to always buy the best available thing when in doubt.
  
  

Here’s what I need:

1°) Files: I was planning to buy a round one (ref 704926), a small flat one (ref 705040) and a big flat one (ref 705192). Glardon/Vallorbe was recommended by some framebuilders I talked with.

2°) Metal saw: Do I have to go with the big ones if it’s mostly for small jobs (fender/rack struts, cutting aluminium plates or steel brackets), or are there way smaller one that’ll do just fine ?

3°) Metal drill bits: I have a Bosch GSB 18V-55 drill. Should I go for Bosch metal drill bits ? The wood ones I bought from them kind of suck, they’re not straight.

4°) Portable vice: I need something small that can clamp on a Ikea table. I won’t put too much force on it, it’s mostly to bend struts and hold pieces when drilling, cutting or filing. Should I go for this very expensive one ?

Thanks in advance !
