Self-contained (single-phase, 0.5 h.p. motor) powered Vertical Head for a Tom Senior M1 Milling Machine. This is the correct unit, with both worm-and-wheel driven find downfeed and a quick-action, lever-controlled feed for drilling. The head swivels and, most importantly, the quill remains in line with this allowing perfect control of angled work. The head may also fit other models of Tom Senior miller and, if you have the dimensions of your column ways I'll check the fit for you. Details of Tom Senior M1 milling machines here
