JET Tools 1791241 1285, 12" Jointer, 3HP 1PH 230V

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 straight knife cutterhead or the helical cutterhead.


  • Large 12" x 84" precision ground cast iron table surface for heavy-duty work.
  • Parallelogram design for close table-to-cutterhead proximity and fast depth of cut adjustments.
  • Rack and pinion adjustable cast iron fence assembly for smooth fence positioning without play.
  • Straight knife cutter head with 3 high speed steel knives create a clean cut.
  • Table "lips" on both sides of cutterhead aid in noise reduction.
  • *NOTE: The recommended max cutting depth for non-rabbeting cuts is 1/8”. The max cutting depth for rabbeting cuts is 1/2" as the manual has always stated.
