I need to get a small kit. What sizes should I start with? I'd like to be able to handle 3-4mm pins, plus start drills for m6-m10 tap/threading operations, and align m7-m12 bolts. Home depot has a nice selection for ~$30 in the cheap mayhew line. Alternatively, I'm thinking of getting a minimalist kit in nicer quality set (perhaps used or NOS). Cost and minimal space in box are a consideration. 6-8 pieces, budget <$50 after sale discounts.
What are your most used/universal sizes?
I'm asking because this may be a good black friday purchase.
