Abstract: A magnetic bar stock puller for a CNC type, numerically controlled turret lathe, the magnetic bar puller configured to engage and pull bar stock for positioning same. In the preferred embodiment of the present invention, the bar puller has a body having an engaging end and a mounting end, the mounting end mounted to a station on the rotary turret. The bar puller is actuated by fluid pressure from liquid coolant flowing from the cooling system of the lathe, the coolant passing through a longitudinal bore in the body of the unit so as to urge a piston, having a high field strength magnet, to migrate within the longitudinal bore towards the engaging end of the bar holder, so as to provide a magnetic field in the vicinity of the engaging end, to selectively engage a bar or other ferrous object in the vicinity of the engaging end of the bar puller.
