Two sizes of inserts for use with the 50mm Axminster O'Donnell jaws. The larger set has a parallel grip of 25mm, will close onto a dovetail spigot of 32mm or will open out into a dovetailed recess of 46mm diameter.
The smaller insert set has a parallel grip of 13mm, will close on an 18mm spigot or expand into a 32mm dovetailed recess. The O'Donnell jaws and inserts offer a great range of workholding options enabling better access to the rear of the work piece, especially when turning bowls.
N.B. The finish may be either silver or black due to changes in legislation regarding passive zinc plating.
