The 1″ x 8 TPI SC3 four-jaw chuck is ideal for use on any lathe, particularly small to medium sized machines and is compatible with the full Record Power jaw range. The compact design reduces load on the lathe spindles and bearings and gives good access to smaller work pieces. The large jaw slides offer unrivalled strength and holding power that cannot be found in other chucks of this size. Supplied complete with a deep wood screw, 50 mm standard jaws and 3” faceplate.
