To drill holes in thin sheet steel as others have said sandwich between to pieces of wood but main thing is do not use a normal jobbers drill but grind one up like a wood bit as a wing and spur.
If you have decent wood bits you could just use one of these but most i have come across aren't even hardened hence the grinding up of the wing and spur.
Worth keeping a few as they are also ideal on plastics and prevent splitting as they exit the hole.
