I cannot comment on the springers but on my HW100, it is allen keys that you need.
For me: big Brownells Master set, bunch of other "magna-tip" type bits, including Pachmayrs, and about 100 Allen keys collected over the years. Seems to meet the requirements.
Drayper expert series electricians set are very good from toolstation must be the expert one though, most drayper tools are just re badged crap these days .
Had a set in daily use for three years so worth the money .
Buying a set with multiple bits gives you the best chance of a correct fit into the screw you wish to turn.
That set of three looks beautiful, but will only properly fit three widths of slot, meaning you may have to grind one to fit any given screw.
Happy Shooting!! Paul.
