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.
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.
The 50mm O’Donnell jaws will accept additional jaw inserts to convert to smaller jaw diameters. The 50mm O’Donnell jaw expands into a 65mm dovetailed recess, and contracts onto a 53mm dovetail or 48mm spigot. The Axminster chuck offers plenty of leeway; externally 60mm to 74mm and internally 50mm to 65mm dovetail or 43mm to 55mm spigot.
All the Axminster jaws are made from stainless steel to protect against corrosion and are suitable for SK100 and SK114 chucks only. As with all our dovetail jaws they simply bolt onto the Accessory Mounting Jaws.
