The Cybertool use the 4mm precision bit standard. There are lots of those bits available inexpensively and usually in large sets. The cybertool bits are held in place by a tiny ball though, and that is not standard. So to hold standard bits you might want to try a piece of shrink tube over the end, or getting magnet in the bottom of the holder.The Cybertool bits are also double ended and 28mm long. Normal precision bits have about the same length, but they are not double ended. There are 8 different double ended 28mm ones available, but they are hard to find and quite expensive. (For double ended it is easier to find 36mm ones, but they will not fit in the tool for carry). An adapter is certainly possible, and most likely out there somewhere. Adapting to something that accepts higher torque than the tool is meant for might be a mixed blessing at some point though.(Instead of an adapter you might want to simply look for a 4mm bit with a 1/4" hex socket. Or for more flexibility a two step solution with something like the Wiha 75806 adaptor which you then put a 1/4" socket on).
Do you think this can be of help Wiha 71314 ?thanks again
Thanks to all opinions and welcome, and sorry for being stubborn,You are right, but I love my sak and I will be looking for any way to make it more versatile.I know I'm limited by the torque, But I will not use it for hard work.
Despite 50ft not being wrong, I disagree with him. I suggest you expand on the 4mm front rather than adding 1/4" bits.E.g. get the Red Cycling kit (adds a L-wrench for convenience) or my favorite from Kraftwerk.
Approaching this from a different angle....If you want the 1/4" adapter, then you are going to need a way to carry the 1/4" bits. Instead of looking for an adapter, how about a Victorinox wrench set. This gives you the "L" wrech that uses the bit, and the carrier which holds a range of bits and the wrench itself. This would probably be stronger, neater, and easier to carry.Welcome to the forum
