How to Change a Drill Bit?

Changing a drill bit is not difficult to do and this is something you probably would have to do often since one drill bit does not do it all for drilling and they do get dull after a while. To start you want to hold the chick and switch the drill to reverse, or take the check key and unlock the bit that way you should then be able to pull out the bit and put the new bit in and then use the chuck key and tighten it back up.
