This is how to insert the drill bit into a Worx drill. This is also how to remove the drill bit from a Worx drill. This Worx drill uses a keyless chuck. Replacing the drill bit is simple but I hope this video helps. I found the instructions that were included with the Worx drill to be rather vague. This is an incredible drill! #Worx #Howto
