These jaws are designed to be used with our Gen 3 GP100 chucks.
Spigot Jaws are serrated on the inside and will hold cylinder spigots much more safely than standard jaws.
Spigot Jaws have a jaw depth of 25mm
Spigot Jaws when closed are 42mm inside and 53mm outside.
Spigot Jaws when expanded are 60mm inside and 70mm outside.
These jaws can be used on a Nova chuck provided the 2 & 4 jaw are placed in the opposite position and GP100 Screws are used.
