RadioShack® 21-Piece Precision Electronic Driver Set

Comments about RadioShack® 20-Piece Precision Electronic Driver Set:

The bits attach to the driver via a plastic receiver and metal grommet that screws onto the plastic threads on the outside of it, similar to a Dremel tool. When trying to tighten down screws, the plastic will not hold the bits in place, even if the metal grommet is tightened as far as possible. Additionally, there is no stopper for the bit receiver, so one can accidentally push the bit in too far, which will require pliers to pull it back out. The case is plastic and not all that durable.

However, the bits are metal and seem sturdy enough. One could almost consider everything besides the bits throwaway. I really just needed it for the T6 & T9 bits.

I needed some Torx bits (actually one), and purchased this kit because it looked like it had some other bits that might come in handy. It does have a nice selection of bits which are of good quality and well-machined. The bit-shafts are ~4mm so they will fit into tighter spots. The kit includes a 4.5" extension for reaching into deeper or hard to reach fasteners.

The handle consists of plastic main part and a brass threaded collar which is used to tighten down the bit into the handle. The business-end of the handle is split and threaded, so that the brass piece tightens down and pushes the split part closer together onto the bit. Unfortunately, this split, threaded plastic part of the handle is too soft, and after one use is already chewed up (though not yet stripped). It would have been better if they had chosen a better quality material for where the bit goes in. The brass part is fine.

The plastic case is perhaps more rugged than the handle. It is about 2" longer than it needs to be and about .5" thicker than it needs to be.

At this price point it is a decent set. I think the problem with the handle won't prevent it from being usable in the short term. The bits could be used with a different 4mm handle down the road if necessary.
