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 38mm O’Donnell Jaw expands into a 52mm dovetailed recess, and contracts onto a 40mm dovetail or 33mm spigot. The Axminster chuck offers plenty of leeway; externally 49mm to 66mm and internally 35mm to 50mm dovetail or 28mm to 43mm 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.
