Hi,

I've just had a new Hi-Fi cabinet delivered and it requires some holes in
the back to feed my plugs through.

The man in the shop described the special drill bits I would require and
when I got home I found that I had some included with my drill.

They are like round pastry cutters in various diameters. The question is...
how do you fit them to a standard corded hammer drill? I can see no way of
attaching them and have read the drills instructions (there is no mention
even though the set of bits and pieces came WITH the drill).

The drill is a JCB corded hammer action.

TIA,

Daz
