Features & Benefits


The ergonomically designed carrying position combined with its light weight (47 pounds) make the Kapex easy to move around the job site. When being transported, the Kapex's head is locked down making it compact and preventing movement. The two handle locations keep the center of gravity of the Kapex close to your body, minimizing the strain on your back. Now, that's smart!

Counter Spring Balanced Bevel

The bevel adjustment on the Kapex is counter spring balanced meaning that you can position the bevel at any angle and the head will stay in position even when it is not locked in place. This makes angle adjustment much less tedious and more accurate. Bevel gauges are on both sides of the saw for quick, easy reference. Using the micro adjustment knob, the Kapex can be dialed in very accurately to fractions of a degree.

Lightweight, Compact Footprint

The Magnesium alloy base of the Kapex was designed to be extremely rigid and durable yet very light weight when compared to other 10" miter saws. At only 47 pounds, the Kapex is truly a portable power tool. The compact footprint allows the Kapex to be placed against a wall when being used saving valuable space in your work environment. Rubber feet protect the work surface.

Bevel Lock Knob

Use the Bevel Lock Knob conveniently located on the top of the Kapex to control the bevel positive detents and to lock the bevel angle. The counter spring balanced head on the Kapex allows you to position the bevel and let go of the saw with the head moving. Use the fine adjustment knob to control bevel angles in fractions of a degree. The bevel knob has three settings: positive detents at 0 and -45 degrees, free movement between -45 and +45 degrees, and free movement up to +47 degrees. Bevels can be made to the left or right and the bevel gauge appears on both sides of the saw.

Special Cutting Position

The Kapex incorporates a special cutting position that, when employed, provides greater than usual cutting capacity by utilizing the back portion of the blade more effectively. The Kapex is locked into the special cutting position with the flip of a lever. Cut crown moulding up to 6-5/8" in the nested position providing a cutting capacity equal to some 12" miter saws. Cut material vertically up to 4-3/4" x 3/4" (as pictured).

Dust Extraction Port

The Kapex features a swiveling dust extraction port which accepts a 27mm or 36mm hose. When combined with the Festool CT 22 or CT 33 Dust Extractor, the Kapex is capable of collecting up to 91% of the saw dust. The dust port has a swivel design to allow the dust extraction hose to be positioned.

Rail Forward Design

The Kapex features a rail forward design which increases precision and creates a compact footprint. The rails are robust at 30mm in diameter and are wide apart. This prevents head play to ensure smooth, accurate cuts every time. The rail forward design also allow the Kapex to be placed against a wall while being used which saves valuable work space. The compact footprint also makes transport and storage easier.

Dust Hood

The Kapex features a dust hood which is responsible for directing the ejection of saw dust from the blade into the dust collection port. This pliable rubber hood arrests chips and helps the Kapex achieve up to 91% dust extraction when using a 36mm dust extractor hose reducing the time spent cleaning up.

FastFix Blade Changes

The Kapex features Festool's patented FastFix blade change system. Turning the FastFix knob locks the arbor, mechanically locks out the trigger and allows the blade to be changed with a single hand. Blade changes couldn't be any easier! A cupped steel arbor nut prevents accidental over-torquing and damage to the saw and blade.

Ergonomic Handle Position

A center-positioned handle allows you to make cuts with either hand making it easier to view the cut. Combine the Kapex with the MFT/3-Kapex multifunction table to place the saw at the optimal work height for greater comfort. A two-stage trigger helps prevent accidental triggering.

Dual Lasers

Easily align cuts from the left or right side of the Kapex using the dual lasers. The lasers clearly define the material which will be removed during the cut. Using the three axis adjustment controls, you have complete control to fine-tune the lasers. A conveniently placed button can be used to turn on the laser without powering on the saw. The lasers are electrically powered and require no batteries.

Blade Kerf & Guard Design

The Kapex blade creates a thin kerf which reduces load on the motor and improves the cut quality. The blades are specially designed to reduce noise levels and dampen vibration. The large 30mm arbor hole reduces blade deflection. The clear, narrow guard is also designed to improve dust extraction efficiency and visibility. These features allow Kapex to collect up to 91% of the saw dust when using a 36mm dust extraction hose, reducing clean up time.

Deck Height

The deck height of the Kapex matches the height of our Systainer 1 storage containers. On the jobsite, you can use one or more systainers to support the material being cut. The difference in height between the MFT/3 and MFT/3-Kapex multifunction tables is also equal to the height of the deck providing optimal work flow and support.

MiterFast Angle Transfer Device

The Kapex includes an angle transfer device named the MiterFast. The MiterFast makes the transfer of inside and outside angles from the workpiece to the saw quick and easy without complex angle calculations. The MiterFast is equipped with an aggressive locking mechanism to prevent slipping. Angles are easily transferred to the Kapex using the reflective surface of the MiterFast and the dual lasers on the saw.

Miter Lock

The miter lock on the Kapex provides an extremely aggressive hold preventing inadvertent movement even when near a positive detent. When you set a miter angle you can trust that it will be exact. The miter scale provides positive detents at common angles for quick reference. The lock is easily released and engaged by flipping the end up the handle up or down.

MMC Electronics

The Kapex features Festool's unique MMC (multi-material control) electronics. MMC provides constant blade speed while under load, provides variable speed control to match the blade speed with the material being cut and protects the motor from overload and damage. A chart on the side of the Kapex head provides a quick reference for the appropriate blade speed based on the application. A dial just above the trigger controls the speed setting.

Miter Scale

The stainless steel, etched miter scale on the Kapex is large and easy to read. Positioned far from the axis of rotation, the scale is extremely accurate and allows precise settings to a fraction of a degree. The miter scale provides positive detents at common angles for quick reference. The scale reads up to 50 degrees to the left and 60 degrees to the right.

Bevel Fine-Adjustment Knob

Use the fine-adjustment knob to control the bevel of the cut to fractions of a degree with extreme precision. The knob rotates and engages a rack and pinion to move the head. The head is counter spring balanced which means that once you set a bevel angle it will not move before you lock it. The bevel angle is very large and easy to read and the distance from the axis of rotation provides maximum accuracy.

Direct Drive Motor

The 1,600 Watt motor in the Kapex utilizes direct drive for a more efficient transfer of energy to the blade. Festool's MMC electronics control the application of that power in a constant speed as you make the cut. The result in a cleaner, more accurate cut than with a conventional miter saw. The motor also has a magnetic brake to reduce the time needed for the blade to spin down.

Trenching Capability

Another unique feature of the Kapex is a special trenching capability. With the simple flip of a conveniently placed knob (shown in photo inset), you can cut trenches to create lap joints or go around pipes and other obstacles. Flip the knob back up and you're back to normal miter saw position in seconds. Turning the knob will adjust the trenching depth. Make quick, accurate dadoes with your miter saw. Now, that's smart!

Keyed, Non-Slip Material Clamp

The Kapex includes a clamp which is keyed to make insertion and removal quick and easy. The clamp will not slide down freely when the lock is disengaged keeping it out of the way while you are positioning your material. A single lever-actuated cam-lock secures the clamp in place and a rubber pad protects your workpiece. The foot on the clamp is oblong shaped providing a flat surface to be placed against the fence.

Cord & Tool Storage

Protect your investment. The Kapex includes onboard storage for the power cord and the arbor tool. A far superior and safer solution to simply wrapping the cord around the saw during transport. This simple feature protects your cord from damage and prevents tripping. The arbor tool is always handy for quick blade changes using the FastFix system.
