Rotary chucks operate the same as the rec tangular chucks and are of the same construction with poles running off the edge. Top plates on all models are of magnetic steel and nonmagnetic stainless furnace brazed construction. Ideally used on lathes, grinders and other machinery with rotating spindles. To withstand the high torque of heavy lathe cuts, dowel pins or screws may be inserted in the top plate. Chuck top plates may be machined for work with odd configurations or an auxiliary plate may be added and removed for other work, leaving the original plate intact.
The ST series is not water-tight and should not be used with coolant. Handles are removable.
