Four into three may be the ticket

I was turning up a custom tap the other day and the only part I had to hold on to after it had been in the mill was the square shank at the end - in went the little four jaw and a fairly quick set up and I was able to get to work. Won't use it every day but it is there when I need it for those small jobs that don't require a big solid 4 jaw.
