I have a cheap rivnut tool (4,5 6,8mm) which has been fine for occasional use.
I've got a project coming up which will need lots of 3mm SS rivnuts, and I'll need a new tool as mine only goes down to 4mm. I'm told with the 'universal' types like mine it's all too easy to break the 3mm mandrel, so I'd like one which sets the maximum pull or whatever so this can't happen. There seem to be a bewildering number of designs on the market, so wondered what the experts would recommend? I suppose up to about 60 quid or so.
