Good question , I have checked on a drill and
NO IT DOES NOT WORK at least on the battery drill it don't work ,probably accounts for the low mileage
If either of you guys want it ( maybe it can be fixed , or might be good for a static display ) you can have it for a donation to Graeme for the upkeep of this site .
Im pleased you asked as I took it for granted that it worked as it looks unused
Will ask locally for another and post here if I find one
