12 Inch Planer Jointer Combo Machine for Woodworking
JET JPJ-12B Planer Jointer Combo 12 in. 3 HP
Product Overview
The JET JPJ-12B combines a 12-inch jointer and thickness planer into one heavy-duty floor-standing machine, making it a practical choice for woodworking shops that need both functions without dedicating floor space to two separate machines.
Powered by a 3 HP, 230V single-phase motor, the JPJ-12B is built to process a wide range of lumber. Its three-knife high-speed steel cutterhead operates at 5,300 RPM and delivers up to 15,900 cuts per minute for efficient stock removal and a smooth finished surface.
One of its most useful features is the quick transition between jointing and planing modes. The fence remains installed during the changeover, reducing setup time and making the machine convenient for shops that frequently switch between operations.
Key Features
12-inch jointing and planing capacity for handling wide boards.
3 HP TEFC motor provides the power required for demanding woodworking applications.
Three-knife straight cutterhead uses high-speed steel knives for efficient cutting.
5,300 RPM cutterhead speed produces up to 15,900 cuts per minute.
Quick function changeover allows users to switch between jointer and planer operation without removing the fence.
Heavy-duty cast-iron tables are ground for flatness and accuracy.
Parallelogram table design keeps the table close to the cutterhead and helps provide precise depth adjustments.
Large aluminum extruded fence offers substantial support for edge jointing and can tilt from 90° to 45° to the right.
Two-speed planer feed provides 16 or 26 feet per minute feed rates.
Integrated dust chute works for both planing and jointing operations.
Fully welded steel cabinet stand provides a rigid base and supports the machine's operating components.
Jointer Performance
The JPJ-12B has a 12-inch jointing capacity and a maximum jointing depth of 1/8 inch. Its 55-inch-long cast-iron jointer table provides substantial support for flattening faces and producing straight, square edges.
The large fence measures 43-1/4 x 5-7/8 inches and can be positioned from 90° down to 45° to the right. Positive stops at both 90° and 45° make common fence settings easier to establish.
Planer Performance
When configured as a thickness planer, the machine accepts stock up to 12 inches wide and 8-3/4 inches thick. The planer provides a maximum depth of cut of 5/32 inch and supports workpieces as short as 10 inches.
A two-speed feed system offers 16 and 26 FPM, allowing the operator to select a suitable feed rate for the material and desired finish.
Cutterhead & Knife System
The JPJ-12B uses a straight-knife cutterhead equipped with three high-speed steel knives. The cutterhead is 2-3/4 inches in diameter and rotates at 5,300 RPM.
The standard knives measure 12-3/16 x 11/16 x 1/8 inches. With three knives operating at the rated cutterhead speed, the machine produces approximately 15,900 cuts per minute.
Motor & Electrical Specifications
The machine is designed around a 3 HP TEFC motor and is prewired for 230V single-phase operation. The listed full-load current is 15 amps, with a recommended 30-amp circuit. The machine is not supplied with a plug, so the appropriate electrical connection should be installed according to local requirements.

Dust Collection
A 4-inch dust port is provided for connection to a suitable dust collection system. JET specifies a minimum dust-collection capacity of 550 CFM. The integrated dust chute is designed to serve both the jointer and planer functions, helping simplify shop dust-management setup.
Construction & Adjustments
The JPJ-12B is designed for stability during heavy woodworking use. Its ground cast-iron tables provide a rigid, flat working surface, while the fully welded steel cabinet supports the motor and planer mechanism.
A large handwheel allows convenient adjustment of the planer table. The parallelogram-style table arrangement keeps the table close to the cutterhead, helping maintain consistent geometry during depth adjustments.
