The NOVA Universal Spanner features over four different NOVA specific functions. This handy all-in-one tool is an economic way to have a dedicated solution in your chuck toolbox. The NOVA spanner has a thin section which makes it easy to position on the chuck insert between the chuck and lathe where standard spanners can be too thick to insert properly. The handle has a good length to provide plenty of grip and leverage. It fits all NOVA chucks for easy and fast loosening and is an automatic choice to add to your chuck tool kit.
