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 degrees 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 straight knife cutterhead or the helical cutterhead.
