The most popular and versatile jaws in our bigger SC3/SC4 range are the standard 50 mm jaws supplied with the chuck and the smaller 35 mm version. So, it made sense for the standard jaw on these chucks to be a miniaturised version of those same 50mm and 35mm jaws – with the hawk beak internal dovetail for gripping spigots and a standard dovetail on the outside for expanding into a recess. This jaw will probably be the most widely used as it is very versatile and ideal for small boxes, small bowls and platters, goblets and many other projects where a small spigot or recess are a logical grip. They are supplied as standard with the SC1 and SC2 chucks.
