The mighty Festool Kapex 120 is still just a miter saw, and it has one inherent flaw that all the other miter saws have: A huge gap in the back of the throat plate that allows any debris that falls below the table to be thrown behind the blade and all over the saw and bench. And since a lot of airborne dust particles are too small to see, that means they're going into your lungs as well.
Enter the Dust Collection Throat Plate. This replacement, zero clearance throat plate has a built-in shroud that surrounds the blade under the table, guiding all the debris to the rear of the saw. And once there, a specially designed vacuum port sucks it all away via a clear vinyl tube connected to your vacuum or extractor.
What's included?
- Throat Plate/Shroud. This will come as two pieces, a front section and a rear section. It replaces the factory throat plate and installs reusing the factory screws.
- Throat Plate Vacuum port. This installs on the rear section of the throat plate with four small screws (preinstalled).
- Rail Stop. This small collar clips onto one of the rails of the saw to prevent it from sliding back all the way. That keeps the blade from cutting too far into the vacuum port while still retaining the full cut capacity of the saw.
- Clear Vinyl Hose. This is what carries the dust away. It connects the throat plate vacuum port to the vacuum adapter.
- Vacuum Adapter. This is what allows everything to work together. On the vacuum side you can hook up to almost any extractor, shop vacuum or even a dust collector. It will accept 2-1/2" dust collection hose, 2-1/2" shop vacuum hose, 1-7/8 shop vacuum hose or 36mm (or 36/32) Festool antistatic hose (NOT INTENDED TO BE USED WITH 27MM HOSE). On the tool side there are two ports. One port is to hook up to the exhaust port on the Kapex. The other port is sized to fit the supplied 1/2" outside diameter vinyl hose OR can be used with 5/8" inside diameter hose (not included or available from us). All fittings are tapered to provide a secure connection to a wide variety of brands of hoses, both new and old.
NOT INTENDED FOR BEVEL CUTS! The throat plate and dust shroud are intended to be used with the blade at 90 degrees to the table. You can enjoy dust-free, quality cuts at any miter angle your saw was designed to make, but bevel cuts will destroy the throat plate and the vacuum port.
In the past we have made our Dust Collection Throat Plates to be used with replaceable inserts that we make, or zero-clearance PVC tape, that way you can always have a fresh zero-clearance kerf on your saw. The Kapex gave us some design challenges that prevent us from using either of those methods. Instead, when your Dust Collection Throat Plate's kerf wears out and you want to replace it, you can come back and order a replacement Throat Plate at any time.

I work in a small area of my basement so dust control is very important. This dust collection fitting now allows me to use my Kapex in that area instead of the garage. It dramatically reduced the dust output and was easy to install. 100% recommend
Couple things, unit does not sit level with surrounding casting. I had to sand down ridges left by printer.
The tube seem to not suck anything. I still see heavy amount of dust off back. I tried cutting ultra slow and still don’t see anything transfer to tube.
Scot,
Hopefully you see this message because I emailed you after your order shipped, but apparently you didn't see the email. In said email, I informed you that there was an early manufacturing issue and that there were two options, sand it down, or I would send you a new one no problem. I am going to ship you out a new one today to make sure you are up and running.
The Dust Collection Throat Plates require very little vacuum to opperate, but there are several factors that can determine how well they work. They are designed to capture debris created from the arbor forward. So if you are cutting small pieces, you won't notice much of an improvement, if any. Wider pices that require a plunge cut, or chop cutting material greater than about three insches or so, is where you will see the biggest benefit.
The size of vacuum hose that you use can make a huge difference as well. It is receommended to use at least 36mm hose. I personally use a 2-1/2' hose to capture as much debris as possible.
