Thank you for asking, Curious. Any hex shank bit will work. I hope this helps and we appreciate your interest in Ryobi! -Keri
If the Ryobi 4v is a 1/4 inch drive I don't see why not ! It's a good set if it fits ! Good luck !
yes 1/2 is the biggest one and 1/4 inch is the smallest,actually the smallest is one smaller than 1/4 inch
The nut drivers are unfortunately not magnetic.
I did and the driil kit
i have no idea what's your question
