The Festool KS 120 Features

The design

It’s immediately noticeable that Festools have invested a lot of effort into the design of the KS 120 miter saw. Everything is positioned in the right way, accessible, and convenient. It may not be the easiest miter saw to use, but it’s also not the most complicated one. The inexperienced users should read the manual before plugging the machine in just to make sure everything is in order. In fact, even the ones that are convinced in their expertise should refer to the manual for guidelines.

As we said, the measuring instruments are excellent. Needless to say, miter and bevel bases are what makes a difference between a cheap and premium unit. This particular one is easily one of the most precise within its own category.

The FastFix system allows you to change the blade fast and easy. Many people struggle with blade changing because it also requires alignments and recalibration. Needless to say, the FastFix system is good news for both professionals and hobbyists.


The safety elements are great. The blade guard is transparent and easy to use. The handle grip isn’t cushioned, but it still doesn’t vibrate as much as one would expect due to the specially designed thin blades. Thanks to the innovative design, everything is within your reach while the machine is under load meaning you can react quickly if something goes wrong.

Dust collection

One of the most surprising features of the Ks 120 model is definitely the dust extraction. The manufacturer claims it’s able to extract up to 92% of dust, which is impressive, to say the least. The crucial thing about it is that it’s integrated into the machine instead of being just a single dust bag mounted on the exhaust part. Instead, you can hook up a hose on the port and use some of the Festool’s dust extractors for optimal extraction. Therefore, you do need an additional accessory for the best results, but 92% seems incredibly tempting.

While it’s a high-end piece of equipment, it still manages to raise some eyebrows when it comes to the price. One cannot say it’s cheap because it isn’t, but it’s certainly a tool worth investing in.

It won’t be as cost-efficient if you don’t use the full potential of it.
