The unique design of the O’Donnell Jaw allows access around the jaws for close-in tool work. The jaws are approximately 49mm tall, tapering to the nose. This tapering gives the jaws their advantage when working close. The centre bore forms a deep recess for holding long spigots and gives rock solid mounting when turning a long way from the headstock without tailstock support. The jaws are dovetailed both inside and outside on the lip. The 25mm O’Donnell Jaw expands into a 34mm dovetailed recess, and contracts onto a 23mm dovetail or 16mm spigot. The Axminster chuck offers plenty of leeway; externally 19mm to 46mm and internally 17mm to 34mm dovetail or 10mm to 28mm spigot.
Suitable for SK100 and SK114 chucks only.
N.B. The finish may be either silver or black due to changes in legislation regarding passive zinc plating.
