These small work-holding jaws have a dovetail outer rim to expand into a recess and a plain bore gripping onto a spigot. The dovetail diameter is 25mm with a 12mm central bore. The scroll of an Axminster chuck allows a wide variation. This allows these jaws to grip a spigot from 4mm to 24mm or expand into a recess from 18mm to 36mm. Please note, this variation means the grip is no longer a true circle at larger diameters. Made from stainless steel to protect against corrosion.

These jaws are suitable for the SK100 and SK114 chucks.
