Festool Kapex KS120: Sliding Compound Mitre Saw

Shop Tested: I love discovering a tool that is well made and does exactly what it was designed to do with minimum fuss. This is the case with the Festool Kapex KS120 Sliding Compound Mitre Saw. This saw has so many helpful features that actually had to read the instructions for the tool to discover them all.

Festool Kapex KS120: Sliding Compound Mitre Saw



The Kapex has the cutting capacity of a 12” saw despite being a 10” saw. The saw features three speeds that can be adjusted quickly to handle materials like plastic and non-ferrous metals. The rails are forward on this saw so you can use it in a much smaller space like my 170 sq. ft. shop. All of the adjustments for angle and bevel are so precise that felt confident enough to use the saw to make precision multi-angle cuts on furniture parts that would normally only trust to the table saw.

I tested the power of the saw by cutting some 12/4 hard maple for a luthier’s bench that was recently commissioned to make. Not only did the saw handle the 3” thickness but it went through it without groaning or slowing down.

An impressive feature of the saw is the dust collection. I was told by the Festool reps that the Kapex paired with the CT22 dust extractor would remove almost all of the dust from a cut. Knowing how difficult it is to keep the dust down on a chop saw, I was skeptical. My doubts were removed once tried it. I would guess that 80–90% of the dust was removed by the 22, making it a great tool to use in a finished home without worry of dust spewing everywhere.

The price of the saw can be somewhat limiting at $1645 (price quoted by Atlas Machinery). However, like anything else in this business, you get what you pay for. In my opinion, this saw is worth every penny and if you buy one you won’t be disappointed.
