I personally think ball drivers sparked a revolution in the types of hardware we use and were a tremendous inovation right up there with CA hinges (love'em or otherwise). Ball drivers actually slowly changed useage from of the old cross-tipped or slotted fasteners to socket heads in much of our hardware and this was a wonderful improvement.

When purchasing handled types definately get the ball drivers. For engine usage I also keep on hand the L shaped types with the ball on the long end and the conventional hex on the short end. These are the ones I use mostly for engine work.

I have never seen the replacable tips before so cannot comment. I to do love the linked ones from RTL having never tryed them but just may soon. You will also find that even standard ball drivers will hold socket head servo screws for example on the long handled drivers pretty well when inserting screws deep down into a fuselage.


Yup I got the balls
