We've noticed that this question is asked occasionally - "Why does my Festool Track Saw seem to be throwing out more dust on some cutting applications than others?

Of course, the vacuum filter bag might be full--but there is also a relationship between the saw blade depth setting and dust extraction, especially when cutting thinner stock.

As the saw blade is set lower and lower, the dust is literally thrown farther up into the blade chamber, and if the blade is set for a shallow cut, more dust is thrown forward. In other words, the angle of the cutting surface of the saw blade changes more to the vertical as the protrusion of the blade into the stock increases.

If that last sentence made your head spin... here's an image worth a thousand words...

Sometimes, of course the cut depth needs to be shallow to prevent cutting into the surface below. Just know to expect more dust in those cases. The Festool MFT table top is meant to be sacrificial and it is normal to cut into the top about 1/4" or so. This is when dust extraction works a bit better. Dust extraction works best at full depth, but you don't want to cut your table in two, especially with the larger TS75 saw.

And always, always...the very first thing to check and then check again is the depth setting on the circular saw blade before cutting. And before cutting did we mention be sure to check the depth setting on the blade? We do have spare parts available on the acetoolonline.com website for the MFT tables if necessary.  Click here to go to the Festool MFT Table spare parts page.
