bought new drill bit instead, I got tired of experimenting with the sharpening stuff

 I want those factory sharpened because if I make a weak edge or something, I thought it might get jammed and try to spin the drill on me and hurt my wrist at a random time if I am using it on thicker metal (I like using the magnetic drill or drill press if possible on things like that, but there are always exceptions). I learned to use a weaker drill with these ... I think the factory made one will wear smoother. I can handle the milwakee m12 fuel when it does that, but if I was using a 18V big brushless drill, I think it could hurt. Granted you are supposed to use two hands but the problem is usually that its sometimes nearly impossible to fixture and you need to brace what you are drilling with your hand/body because of vibration to have any semblance of 'work flow' unless you are 'the clamping doctor' with unlimited floor space for weird fixtures.
