It would be nice if someone could make a shorter self feed or auger bit for drilling holes in wood. Something that with that small section of your average keyed chuck, would give you the capaibility to drill through no more than 2 studs. This would really help fit your average right angle drill into tighter locations between studs and joists potentially. Or perhaps a system by where the bit itself is relatively short but extensions are readiliy available to get it back up to the average length, longer lengthes, etc. Also make it serviceable like the MIlwaukee switchblades as an example.
