This 115 in 1 magnetic screwdriver bit set, with precision hand working tools in a case, is perfect for the workshop. It is also perfect for a dozen different things I can think of. It has just about every bit I can think of that I need to use and it is all in a handy case so that I can carry it where ever I need to go. I have used it on my automotive electrical that i was working on, fixing some of the broken electronics that have been sitting around for a while and even to fix the eyeglasses when the lens popped out! Handy! It is well constructed and will last a while if you take care to always use the case for the bits! This makes the perfect addition to my larger tools in my workshop! Love it!
