I'm looking to pick up a ratcheting screwdriver, and looking at some online, do they only take certain proprietary bits? I was under the impression that I could take any 1/4" bit, like you'd use on an impact, and slide it in. A few I've seen seem to be only usable with the bits they come with. Is there some term I should be using to narrow my search for one that cane take any 1/4" bits? I'm looking for one like that because I have already have stacks of bits.
If anyone has a rec for a non-China made one, too, I'm all ears.
Some ratcheting screwdrivers use “standard” bits.
Some use propritary bits.
Some can use multiple types of bits.
It sort of varies.
Even 1/4 drivers can vary, since there are at least a few different standard systems.
1/4” “Insert” bits, are the standard short bits with the narrow groove which are about 1” long. These are svailable in longer lengths, and from a few manufacturers in shorter lengths, but 1” is standard.
These are probably the most common bits.
1/4” quick change bits are usually longer, with a larger wider groove meant for a ball retention system in the driver or bit holder.
These are easier to chuck by themselves in a drill chuck, or they can be held in a bit holder, which holds them mire securely then insert bits.
The quick change bits are also longer, so the wide part of the bit holder is further from the bit tip, which can aid in getting into narrow recesses gor screws.
There are also interchangeable screwdrivers that use 1/4” hex blades, but the blades are longer, so regular insert bits won’t work.
In certain parts of Europe, llike Germany, there were metric hex bit standards like 4mm and 6mm.
Wiha Dive-Loc VI and Topra and Wera Vario screwdrivers use the 6mm standard blades still.
I believe some Japanese manufacturers also made 6mm blades as well, but it’s less common now.
