I think I’d agree with Mort on this, for it’s designed purpose it is great (perhaps a little extra length needed), it also seems to clear the debris better than a standard drill, I guess this is due to flute design.
The idea of receiving a drill bit with the clips is ideal and more likely to be used for its design purpose. Similar to getting the screwdriver bit with screw tubs etc.
Many would likely use a general bit as opposed to a specific length/design but I do believe that there is a tool for each task so would purchase as required.
