Powermatic PM9-1791307 1285 12″ Jointer with Helical Cutterhead, 3HP 1PH
Powermatic 1791307 Description
This 12″ jointer offers big capacity and performance in a machine that is loaded with features. Large center-mounted fence assembly adjusts easily via rack and pinion system with ram lock. Preset stops on the fence body allow for fast angle set-up at 45° in and out, and a positive stop for perfect 90° angles. The parallelogram design keeps the table in close proximity to the cutterhead for improved finish and allows for a fast depth of cut adjustment. This design also ensures the tables remain perfectly parallel even after years of tough duty. Choose either the standard three-knife cutterhead or the solid steel Helical cutterhead. The helical system makes fast work of knife changing and never needs adjustment.
