So I found https://www.amazon.com/VonHaus-100-Piece-Titanium-Storage-Drilling/dp/B078XHWVVN/ and thought it looked pretty complete. Those WERA bits look really cool. Specifically this: https://www.amazon.com/dp/B00I8MYMT2/ref=psdc_2445469011_t1_B016NC7NN0 but it is really pricey. It looks like that single set though might have everything I need for the driving side of things. Anything common that isn't in there? They don't make drill bits though, right? So I then still need one good set of drill bits that has everything. The problem is that they almost all have driving pieces, so then I'm stuck with a bunch of overlap. Are those WERA bits really worth 5x the price?
