Tap and die set. Suggestions?

Just go to a decent hardware store and get the one size you need. You'll get a top quality one for not a lot. Buy a decent set and you'll have a lot of stuff you'll likely never use.

yes to this ^^^

its exactly what i did, so now i own m5 and m6 taps as they are the only ones i've ever used, and if i needed to get another size i'd just get that one size. while i like having shiny tools, i really dislike having shiny tools that i never use, especially if they are in a set, cos then you cant even get rid of the surplus cos noone wants to buy a set with bits missing.

Sorry not tried to be odd, but am noticing sstuuf i'm taking apart that i like to run a die to clean the threads on pedals and odd bolts to but then that me being fussy or not being so fussy as what goes on my bike.

brass wire brush will sort you out for pedal threads, though not as satisfying as running a die round it. however, i suspect that pedal threads as an example are of a weird size that wouldnt be included in a normal set anyhow?

for those who've never used them, this is what i was always told: full turn on, half turn off remove swarf, full turn on, half turn off remove swarf.....
