axxe is right on......gun screw heads generally have deeper slots than others. therefore screwdrivers made for smithing have heads tapered to fit all the way down into the slots. They wont try and walk out stripping out the head. Also they are harder and the driver head wont strip or bend as easily. The set you show rich is a good one. You will probley find 2 or three is about all you normally use. That is unless you have a very large collection of firearms from all over the world with many different sizes of screws. Also use them for scope work.
A picture is worth a thousand words !!!
the blade on the left is a Flat Ground Blade...notice how it DOSNT fit all the way into the slot.
The blade on the right is Hollow Ground...going all the way to the bottom of the slot and applying toraque to all portions of the head equally.
Hollow Ground has very litte or No taper and Flat Ground has taper.
I like visuals.......
Thats why I like visuals. I can sit in an 8 hour class and have an Idea....lot of times wrong. Give me 5 minutes hands on, let me screw it up once (sometimes twice).....NOW I'VE LEARNED SOMETHING that stays with me..........LOL.....thats what they call Experience......
I hate to say this, and I mean no insult, but it can't be a good set: It's to cheap. It's like the one I bought.
I've done 35 years fixing cars, and airplanes, and quality tools are not cheap. The stuff on the Snap On truck really is better. Is it twice as good (it is 2 or 3 times the price) as Craftsman? No, but it is better. Is it twenty times as good as the cheap set of hollow grounds I bought? No it's infinitely better! Because it works as opposed to failing the first time it is stressed. Those good sets that run 75 and up are just starting to fit the price range I would expect to pay for a good apex bit set that will not screw up an airplane or a gun. The cheap ones will work until you come across a screw that is very tight, then the tips will bend, strip, or break.
After I bought my first Craftsman auto kit I was afraid of losing them in junk yards so I bought a cheap Japanese set for that. The ratchet broke the very first time I put it to a bolt. Over a short time extensions sockets, everything in the kit failed. When I started racing my mentor told me not to bring my good tools to the track because you'll lose them when you lend them out. I ignored him. I was in airplanes by that time and I intended to maintain my race cars just like I maintained airplanes, and that requires a tool that will work. I never lost a tool at the track because I always made sure I got it back.
My kid just landed his first airplane job. He is having a heart attack over the prices of the tools I'm making him buy. But he grew up learning from me and he understands. Buy it once and if you don't lose it you never have to buy it again.
OK, thanks. What brand is a good gunsmith screwdriver set? My Wheelers seem to work fine.I hate to say this, and I mean no insult, but it can't be a good set: It's to cheap. It's like the one I bought.

The problem with cheap tools comes when suddenly they fail which happens when you have to push them hard. It's not a huge deal on a rust bucket in a junk yard, but on a nice piece of equipment, if it screws up the machine too, it's bad news.
