the operator from pushing down directly over the cutter, something you shouldn’t be doing anyway. For edge jointing operations, the guard is adjusted to allow the material to pass between its end and the fence. Here again, the unused cutter remains covered throughout the operation.

The bridge style cutter guard is needed only for jointing operations. The guard remains in place without modification when the jointing table is rotated up to convert to the planer mode.

Planer Mode

The JET JJP-12 Jointer-Planer is a fully capable thickness planer with a 12”-cut width and handles a whopping 8 ¾” maximum material thickness. The maximum full-width cut depth is 1/8” with 5/32” being the maximum cut on narrower stock. Naturally, lighter cuts put less stress on the wood itself and often produce much better results. The 5500 RPM cutterhead speed means a constant 20 FPM feed rate is a good balance between quick material removal and a clean, smooth surface.

In planer mode the material feed roller system is engaged by moving an exterior handle to the On position. That produces a material feed rate of 20 FPM. (feet per minute) The control lever is moved to the Off position when the JET JJP-12 Jointer-Planer is changed to the jointing mode.

In the planer mode the JJP-

12 handles boards up to 12” wide with power to spare.

The cutterhead assembly is fixed and includes a row of gravity-operated anti-kickback fingers for safety. A serrated metal feed roller is designed to resist contamination and maintain a consistent material feed rate for the best results. A rubber-covered outfeed roller keeps the stock moving without marring the freshly planed surface.

The 21 ¼” by 12” planer table adjusts up and down through a large handwheel (with spinner handle) on the infeed end of the JET JJP-12 Jointer-Planer while in planer mode. A scale on the handwheel hub shows the amount of change partial turns create while a full height scale with pointer shows overall cutter to table distance. The planer table is locked with a lever-type handle.

The JET JJP-12 Jointer-Planer was designed to bring the much needed jointing and planing capabilities to your shop in a single, space-saving 55”-long by 39 ½”-tall (top of fence) and 32”-deep (fence at its widest setting) package. Because of its space saving design and our focus on accuracy, function and durability, the JET JJP-12 Jointer-Planer is as economical as it is versatile.

One of the standout features of the JJP-12 is its 12-inch planing capacity, accommodating larger workpieces than many other models in its class. The precision-machined cast iron tables offer a flat and stable surface, enabling accurate cuts and reducing the risk of snipe—a common issue when planing. The infeed and outfeed tables are designed to provide excellent support for the material being worked on, ensuring consistent thickness across the entire length of the board.

The JJP-12 is equipped with a powerful 1.5 HP motor that delivers efficient and reliable performance, ensuring that it can handle a variety of hardwoods and softwoods with ease. The machine boasts a direct-drive system that simplifies operation while maximizing power transfer to the cutting blades. This means faster, smoother cutting without the vibrations that can sometimes plague other jointer-planer models.

Another impressive technology feature of the JJP-12 is its quick-change function, which enables users to easily switch between jointer and planer modes. This not only saves time but also enhances productivity, allowing woodworkers to seamlessly transition between tasks. Additionally, the Dust collection system on the JJP-12 is top-notch, featuring a 4-inch dust port that connects to standard dust collection systems to keep the work area clean and manage debris effectively.

Safety is a critical consideration in woodworking, and the JJP-12 addresses this with features such as a safety switch and an emergency stop button, providing peace of mind while operating the machine.

In summary, the Jet Tools JJP-12 is a well-rounded jointer-planer combo that embodies superior construction, ease of use, and efficient performance. With its powerful motor, spacious working capacity, and thoughtful safety features, it stands out as an essential tool for anyone serious about woodworking. Whether you are flattening boards or achieving precise thickness, the JJP-12 delivers the flexibility and reliability that professionals demand while being approachable enough for hobbyists.
