"Hi, I?m Danny from Tampa, Florida and on behalf of Expert Village I?m going to show you how to use and maintain a electric hand drill. Now I?m going to talk about changing the drill bits on your drill. I would show you this drill first this is a keyless drill. If you want to put a bit on all you do is hold this right here. Hold it until you have a nice firm grip and as soon it is tight you would be good to go on this. If you have this type you have to use a key. So it is the same thing but you have to use a key to tighten it. You just turn it like that and you tighten as much as you can because you don't want these bits to fall off. As soon as that is tight you would be good to go and you can start drilling."
