in 2004 we were expecting a high CAT 3 storm, and for the first time, I cut and painted plywood for the 27 windows in my frame house... about 1/2 way through installation, my old 12v cordless drill's battery gave up... I had been using Torx deck screws, and had to finish with regular Phillips head screws and an old Yankee Screwdriver...after that, I wanted to upgrade the Yankee Screwdriver to accept 1/4" bits... going to Lowes and Home Depot, I was met with.... you want a what?....
I built a home brew adapter, then found a commercial unit... in case you don't know what a Yankee Screwdriver is...it is a push drill, the spring return helix shaft rotates cw or ccw as you push... I now have two
this is the back up for the 18v Ridgid cordless
