Add power to your drilling and tapping, and save hours of hand-cranking. Reed offers two adapters to fit popular power drives. The adapters require Reed's 700PD power drive to do the work. For Power Tapping, the TMPDA fits the 13/16in boring bar that is common on popular drilling and tapping machines. By tightening down the set screws, the TMPDA1516 may also be used on 13/16in boring bars to power tapping/drilling machines. The operator manually turns the star feed on the tapping or drilling machine while the power drive adapter turns the boring bar. With the 700PDTMPDA option, the Reed 700PD Power Drive comes with a free TMPDA adapter.
