Can I borrow a drill or chuck adaptor for a 16mm drill bit

Hi

I need to drill a few 16mm holes in masonry. I've got the drill bit and hammer drill, but have found that the 16mm drill is too big for the chuck.

Does anyone have a drill with a chuck that can open wide enough, or an adaptor I can borrow?

I live on Umfreville Road and can pick up and return.

Thanks v much

Jeremy
