How many bits fit in the handle on the williams? I'm looking for a screwdriver that will hold about 8 to 10 bits...2 slotted, 2 phillips..with the rest torx, tamper torx.
My CASE IH (Williams re-brand) ratchet screwdriver holds 8 standard 1" bits easily to where I can just dump them out in my hand and then dump them back in and put the cap on without issue. I can get 9 in the handle no problem with a little finessing of the screw-on top making sure that one of the bits takes up the hollow space in the screw-on cap so it doesn't get in the way of the threads. I can fit 10 bits if I stack them all directionally and methodically and make full use of the hollow cap, but that would be unrealistic to do every time for anything but very occasional use.
Remember, you can always leave a tip in the end of the screwdriver as well. The magnet is strong on this screwdriver and the 1/4" hex shaft slot is pretty deep, so the bits don't come out of the shaft unless you want them to. Since #2 Phillips is my most used bit, I leave one in the shaft at all times and I keep a spare in the handle along with my other bits.
One thing I have done in the past is to grind the bit shafts about 25-50% shorter (for tight clearance applications) like I show in my pic below. You could do that same thing to all your ratchet screwdriver bits and then you could get even more in there.
