My ball-driver set

I have several different sets of ball drivers after racing 1/8 scale offroad for years. From the HUDY racing stuff that is very expensive and precise, to the OFNA racing tools that fit in the end of a Makita power screwdriver, to the el cheapo L bend Ace hardware ball driver sets in there own plastic holder. You know which one I go to the most?? The cheap ace hardware stuff. Next up would be the Ofna ball driver tips, because they do fit nice in a power screwdriver, then the HUDY tools because they have a severe undercut to the ball driver section, which allows you to start or drive screws at a sharp angle, like say engine mount screws under a muffler. The problem with the severe undercut on the ball section is that it makes it easy to break if you put to much load on it at an angle. Small diameter ball drivers should only be used for starting screws, you get up around 20-30ftlbs or so and the heads start to twist and ultimatly fail.

I have both metric and standard for all 3, hand tools and power screwdriver styles. I like the Ace Hardware sets the best because they are ball driver on the long end, and a straight cut on the short L bend.

Bondhus makes about the best ball drivers. I have some of those as well. The Tower Hobbies set you posted dave is Bondhus.
