The Silent-Power® spiral knife cutterblock reduces the noise emissions when planing by more than a half. Specially developed tungsten carbide blades with their constant pulling cut, guarantee a tear free planing finish of every wood type. The optimized extraction hood ensures that the noticably shorter chips are effectively extracted and land considerably more compact in the dust bags. This more compact filling of the chip bags, saves you from having to frequently change the bags. Maximum reliability and highest level of jointing quality - the innovative new development from Format4 offers a jointing system with knives that have a usable life up to 20 times longer when compared to a conventional HSS-blade system. Damaged blades can be exchanged individually, removed and replaced with a few turns of the hand. The advantages at a glance ...

For decades the Format4 system with double sided disposable planer knifes proved its advantages. Perfectly manufactured and adjusted in the factory, you do not have to adjust the planer knives and expensive aligning tools do not have to be purchased.


4¾" (120 mm) cutting diameter and the unique Format4 knife system with reversible blades - for many decades a guarantee for excellent jointing results. Maximum blade life and minimum cost of the blades ensure considerable savings.

With the amply dimensioned planing height of up to 254 mm, even processing large solid wood trusses is simple and effort free.
The fully electrical “Power-Drive” planer table control offers the most precise adjustment and repeat accuracy. With a twist of the knob, you can quickly adjust the planing height, then fine-adjust using the button. An integrated LED-display displays the actual value.
The programmable “Digi-Drive” planing table control makes it possible to enter the planing height using the numeric keypad and the planing bed positions itself automatically and precisely. Two intregrated LED displays show the current target and actual values. To optimize production you can save incremental measurements and individual planing table positions.
Regardless of the type of wood and grain, the variable feed speed of between 4–16 m/min always guarantees a perfect planing result.
4 trapezoidal spindles guarantee exact adjustment precision and ensure maximum planing bed load. Longitudinal guides integrated into the side of the machine chassis absorb the pressure that is put on the outfeed side and ensure that the planing table is guided with an accuracy of a tenth of a millimeter.
The aerodynamically optimized construction of the dust extraction hood with its ample chip space guarantees an ideal chip extraction and clean working surface.
A recommended option when planing with a small depth of cut, with very thin workpieces or workpieces with different thicknesses.

The tried and tested Format4 operating concept reduces the effort in changing from jointing to planing to a minimum. The intuitive table clamping system makes it possible to synchronously lock and open the jointing tables with a twist of the hand, industrial springs assist in the opening.

Accurate adjustment is obtained with Felder’s patented planer adjustment system, which incorporates lateral prismatic guide rails.
With the new ergonomically shaped depth of cut adjustment handle, you can adjust the depth of cut quickly and precisely.
The depth of cut can be set to any depth up to ⅜" (8 mm). Using the integrated magnifying glass you can view the set depth and achieve the exact results that you are looking for.

A masterpiece of stability, precision and space saving design - the innovative parallelogramm Format4 jointing fence system design allows you to be able to position your machine directly next to the workshop wall, without restricting the planing width. The jointer fence can be tilted to any position between 90°–45°, the jointer fence will always remain flush with the jointing table.

Maximum operational safety and an unprecedented ease of use. The space saving jointer guard integrated into the machine chassis stabilizes the workpiece when jointing and beveling.
When processing thin or narrow workpieces the new tiltable auxiliary fence attached to the jointer fence, guarantees a safe and comfortable planing operation.

Using the tried and tested Format4 table extensions it is quick and easy to extend your planing table by up to 39⅜" (1000 mm) without the use of tools.

A power feeder increases the safety and comfort when jointing without reducing the planing width. The constant, steady pressure ensures an absolute symmetrical planing finish.
