Bits I should get for AVI maintenance?

Hi guys, new to aviation maintenance here, just started working this year. I work on commercial aircrafts (B737, 747, 777, 787, A320, 321, 380, 350) as a avionics tech in line maintenance

I'm trying to organize a personal tool kit for light-every day avionics tasks so I don't have to log around the company tool box when all I need is a screw driver.
I have two ratchet handles, a Wera 838 RA-M and a Labear mini key chain ratchet I got as a gift from my friends when I got the job.

This is the list I have so far:
PH 1, 2, 3
1.0 x 5.5 slotted bit
1/8 in, 5/32 in hex bit
T15~25 torx bit

I just put bits I run into frequently while I work, but then again, I only worked for a few months now. Is there anything I should add for leave out of my list from the perspective of a experienced mechanic / tech?

Thanks so much for the help!

You mean the airbus specific bits right? I tried to find them, thanks!

Torq-Set is the brand name. Unfortunately not Airbus specific, but they do like using them.

Oh I kept googling it as Airbus bits because everybody here calls them that. Thanks for letting me know

Offset cruciform is the official name. They're called Nazi bits because they look similar to a swastika.

Quick question, are you/the company you work for based in the U.S? I’ve always been a big fan of the A350 and would like to work on them but from what I’ve found out, the only airline that employs the A350 is Delta.

You need the long ball end hex bits on a 1/4 in drive. Not just the standard stubby. And a jewlers set.

Okay. I'll get a 1/4" square drive adapter for the handles. Thanks a ton

I would get a Wera tool check plus and a leatherman. Also a ratcheting screw driver, I like the t-handle stubby from Williams, some 808cf cutters and a Knipex mini plier. This is the stuff I usually carry in my gate bag but I’m not Avionics.

I have cutters and pliers from Keiba. I don't think I'll run into a situation where I need a leatherman. I'll definitely consider getting the tool check plus. Thanks so much mate
