Our helical head with its spiral rows of carbide inserts creates ultra smooth surfaces yet has an exceptionally long cutter life.
Our Quick-change knife system makes this once frustrating task quick, simple and automatically accurate. We include a pair of magnetic tools - shown here removing a knife retainer plate – that helps prevent nicked fingers!

An important feature of the JET JWP-15DX is how easily the knives are changed and set. A specially designed mounting and alignment system eliminates one of the most frustrating aspects of using many planers - changing and aligning its knives.

When a knife becomes dull or damaged all one has to do is remove the 8 retaining screws and carefully remove it. The cutterhead has two precisely machined and located pins in each knife seat that mate exactly with two precisely

machined and located slots in the knife. When changing or flipping a knife simply place it over the pins on the cutterhead seat, replace and tighten the 8 screws and it is automatically aligned and ready for use. No further adjustment is required.

JWP-15HH with the Helical Cutterhead

While designing the JET JWP-15HH we developed a criteria for a unique cutterhead that would insure the unmatched performance and reliability. That design specification meant the choice was very simple - a helical cutterhead with carbide inserts.

The JET JWP-15HH cutterhead is so effective because its 68 carbide inserts are arranged in four spiral-shaped rows. The inserts have a 4” radius ground into them and are mounted so they approach the wood at a 14-degree angle. That creates a true shear cut that eliminates much of the impact and the resulting fiber disturbance common with other cutterhead designs. Also contributing to this excellent surface finish is the profile of the space between the rows of carbide inserts. These areas are specially designed to carry chips away from the cutting area and eject them before they cause any problems for your work surface.

This helical cutterhead cuts so efficiently that it makes surprisingly little noise when cutting wood. In fact, it is so quiet, that new users often think that the JET JWP-15HH is not cutting wood at all! That is until they see the freshly planed surface emerge from the other side.

The helical cutterhead inserts are precisely machined from solid high-grade carbide, each with four identical cutting edges. If an edge goes dull or is damaged, you simply index it to the next cutting edge! Each insert has a marking at one edge that makes indexing all or any number of them the same way very easy.

JWP-15HH, JWP-15DX specifications

Jet Tools has established itself as a prominent name in the woodworking industry, producing high-quality machinery designed for both professional woodworkers and hobbyists. Two of their standout products are the JWP-15DX and the JWP-15HH, both of which are exceptional planers known for their durability and performance.

The Jet JWP-15DX is a powerful 15-inch planer that efficiently handles a wide range of materials. One of its main features is the three-knife cutter head, which ensures a smooth finish and improved chip removal. This design allows for more cutting action with each pass, reducing the workload and time required for projects. Additionally, the JWP-15DX boasts a robust 3-horsepower motor, providing ample power for heavy-duty tasks while maintaining a consistent feed rate that enhances precision.

Another significant characteristic of the JWP-15DX is its adjustable depth control system, allowing woodworkers to make precise adjustments easily. The integrated digital readout provides clear visibility of the settings, ensuring users can effortlessly achieve the desired thickness. Furthermore, this planer features a table extension that provides support for larger workpieces, enhancing stability during operation.

On the other hand, the Jet JWP-15HH comes equipped with a helical cutter head, featuring 40 insert knives that deliver a superior finish and significantly reduce noise levels during operation. This technology allows for a smoother cut and less friction, resulting in extended tool life and reduced maintenance. The JWP-15HH also has a 3-horsepower motor, mirroring the JWP-15DX in power but taking performance a step further with its innovative cutter head design.

Both planers incorporate Jet's signature build quality, intended for long-lasting reliability in demanding environments. The adjustable infeed and outfeed tables enhance user convenience and ensure optimal performance when working with larger materials. Moreover, their dust collection ports allow for efficient debris removal, keeping the workspace cleaner and safer.

Overall, the Jet JWP-15DX and JWP-15HH stand out in their class with advanced features, innovative technologies, and excellent build quality, making them ideal choices for woodworkers looking to achieve professional results in their projects. Whether opting for the efficiency of a three-knife cutter head or the quiet performance of a helical design, both models deliver exceptional reliability and performance.
