Like in the picture. It's doing a great job (floorboards and skirting boards) but it keeps working itself out of the drill - I can see it creeping out gradually, and after about a minute of use it falls off. I've got the chuck as tight as I can get it.
It's actually worn away the spindle bit that goes in the drill, too, presumably it is constantly slipping inside the drill.
I'm using a very heavy duty sandpaper grade on it - 40 grit - for the first pass to take all the crap off. Could that be part of the problem?
Greatful for any advice.... cheers
