Powermatic 12" Parallelogram Straight Knife Jointer with ArmorGlide 3hp, 1PH, 230V - PM1-1791241T

Now featuring ArmorGlide Technology, the Powermatic 1285T 12-Inch Jointer offers big capacity and performance in a machine loaded with features. A large center-mounted fence assembly adjusts easily by a 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. This model features a straight knife cutterhead.
