Electric drill (Brantham CO11)

Black & Decker electric drill - D154RG 500W.
Variable speed drill with reverse function in working order. Also has a switch for hammer action, but this seems very stiff. May just need a bit of muscle or a bit of WD40?
I believe the cord has been changed by the previous owner, as it's longer than I would expect on a drill, and the rubber cord support where the cord enters the drill is damaged and could probably do with changing at some point.
A chuck key is included.
Located in Brantham on the A137.
