I have a bunch of drill bit sets in stylish cases, each drill bit is in a hole that is difficult to install and remove. Then of course the drill I need is missing and all the little ones are broken etc. It's always that little disappointment that stops the project. This large set of drill bits is a pleasure to have a tool handy in my garage. Sentence. There are many, many small drills that *break*, so many replacement parts are readily available. There are no slots to stuff them. It's just a big box of drills divided into handy compartments. Sometimes a product comes along that makes life a little better, and this is one of them.
