Not sure if you are talking about the 3 jaw chucks on the same page but the holding power is not as good as a 4 jaw. They may work for smaller or spindle projects but as for holding bowls and vases there is no way. The ones I mentioned I had are for woodturning. The others are mostly used it metal work but I do have 1 X 8 3 jaw I use and works pretty well for making mini birdhouses or finials but that is all I use it for. I just happened upon it at a garage sale.
