I recently tested 14.4-volt drills from the two companies currently selling them. DeWalt introduced the first one more than a year ago. And early this year Sears started selling its model 315.27194 — a 14.4-volt drill made to Craftsman specs by Ryobi. I took both of these with me to the job, and after a few weeks, I lent them to the guys in a busy cabinet shop. Here's how they compared. Volts vs. Amps Ten years ago I bought my first cordless electric drill. It was a 7.2-volt AEG and could go 0 to 600 rpm. It was state of the art, but not for long. Other companies followed suit with 8.4-, 9.6-, and 12-volt tools.
