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.
These jaws are suitable for the SK100 and SK114 chucks.
N.B. The finish may be either silver or black due to changes in legislation regarding passive zinc plating.
