JET JPJ-12B 12" Straight Knife Jointer/Planer 3hp, 1PH, 230V - JT9-715100
You don't have to choose between buying a jointer or a planer. With the JPJ-12B, you can have both. This versatile machine features an extra-large aluminum extruded fence with centered controls for quick adjustments, a built-in dust chute capable of handling both planing and jointing operations, and a powerful 3-horsepower motor that can handle the toughest lumber.
A heavy-duty, fully welded steel base cabinet houses the motor and the planer table mechanism, while providing solid mounting for the associated controls and support for the jointer table and fence assemblies. Best of all, the fence can stay put when changing over functions.
