Hello, I have a newbie question. What drive sizes should one get for working on automobiles? I see that the three most popular are 1/4,
3/8 and 1/2. Why are there three different sizes? Is there a functional difference between them?When putting together a tool set for working on cars, do you buy sockets for each size drive or use converter bits? Is it safe to use smaller sockets with larger drives (using converter bits)?
Thankyou
