Designed by master stone setter Jura, our set of 10 Jura hand chucks are color-coded for easy identification and are great for use with beading tools, bead splitters, burnishing tools, and more. The 5 half-round handles provide a great reference point when using beading tools. The 5 round handles are ideal for burnishing and bead splitting.  The comfortable, plastic heads of the handles will impress you while the sleeve/collet system is easy to use and provides stability.
