This is a used 4-step Drill Press Spindle Pulley. The pulley was removed from a Rexon RDM 150F drill press. I only retired the drill press it came off of because the column mount bracket for its table broke. The belt channels and center bore are in great condition, but the rims between channels are marred in a few spots as pictured above. Nothing that will affect performance. If you have any questions, please ask.
