Spigot Jaws for the Oneway Stronghold Chuck (30589, sold separately) are deep to provide a better grip on smaller parts. Both outside and inside surfaces of the jaws are serrated to grip the workpiece.
Notice: If your lathe has less than a 16″ swing, the Oneway Talon Chuck (20761, sold separately) is recommended. Stronghold Chuck jaws are NOT compatible with either the original Oneway Chuck or the Talon Chuck.
