Another of the most popular jaws for full-size chucks – Pin jaws are ideal for smaller chuck projects, including pre-bored material such as peppermills and similar projects. The end of the jaw is dovetailed, so it can be used on its own as a delicate grip – or the jaw can be inserted full length using the back jaw face as a register and providing wall support to prevent the workpiece from being knocked from a dovetail only grip. The dovetail at the end provides additional security in expansion mode.
