Hi all, Been using my MT55 quite extensively this past week and overall it's been a pleasure to use, coming from a TS55 the rails are fantastic as is the scoring function.  The only thing I'm a little surprised at is the dust collection, through my Festool Midi (with new bag) it doesn't seem quite as effective as my old TS55 was at dust collection. There seems to be more fine particles in the air and at times there is a fine layer of dust actually on the saw itself. Also I'm finding that the 27mm hose doesn't fit into the outlet particularly well (it does fit though) and does have a tendency to fall out if there is any stretch at all put into the hose. Just wondering if there is an adapter or something that ensures a better fit with the hose and also if there's any way I can improve dust collection in use. As I say overall I'm very happy with the saw and rails. Thanks. |

That's odd, I would be surprised the MT55 does worse than the TS55 in dust collection. I assume you're making a cut where the blade isn't exposed, you have the blade set so it only cuts at the depth of the the material or a little below. You aren't working with incredibly thin stock? Do you have the clear plastic dust collection piece extended down into the work as well?
I only get a little residual dust inside the MT55cc which I assume is from the static charge. I practically see nothing coming out of the saw from the topside, even with a headlamp pointed ahead of it.
As for the fit: I had a Shopvac hose (1.5") with a Bosch VAC024 adapter on it and when you firmly wedge it into the port it tends to stay in there unless you pull it out at an angle. I'm on a different setup now for my dust collection but I haven't used the MT55cc with it yet. The end of the hose is effectively the same, but the Bosch hose has a larger effective ID on the adapter since it screws onto the outside of the hose versus sticking into the inside of the Shopvac. I adapted a 35mm antistatic Bosch hose (Long story, got two on a sale) and they have effectively the same adapter.
My personal results are with larger diameter hoses and I'm using a cyclone powered by a Shopvac with good cfm and static pressure specs but I believe the static pressure will always be lower than any proper dust collection vacuum (Bosch, Festool, Starmix, Karcher, etc).

I mainly use a 27mm hose off a festool ct26. It can pop out if tweaked the wrong way but I jam the bastard in there and usually I'm good. As far as dust collection goes, there should be nothing airborne unless you're shaving off the edge. The clear plastic section at the front of the saw can be moved right down to the workpiece to improve dust collection.
How are your filters on your vac? Is there a clog somewhere either on the saw or vac?
A side note, dust collection will improve with the bigger hose diameter. You shouldn't be seeing airborne dust with the hose you're using however.

Thanks for the replies, I'll have a good look at the hose and filter tomorrow and see if there is a blockage of some sort. Everything I've seen with the enclosed blade housing suggests collection should be more efficient than the TS saws.
Incidentally does anyone know what the standard hose length is on the festool vacs, is it 3.5m? I might go down that road after I get the d/c sorted.
Thanks.

Should be easy to make sure that the vacuum is sucking all the way from the saw. just go manual-on.
I do as @ghostfist says, and "Jam the bastard in". Sometimes it jumps out.

The next size hose fits tightly over the top of the MT55 dust port- I think its the 36 mm hose. I use a gray festool one that isn't anti static on my saw and it never comes off. Even if I run the saw with no vac almost all the dust flies directly out of the port so it's surprising to me also that you are having any issues. I have wrapped beams out of MDF inside clients finished homes with no complaints. Almost no dust at all.

I'd be curious as to what the difference would be between the festool and mafell as far as dust collection goes. I'm very happy with the collection on my mt55 but I've never done or seen a side by side.

I'll be a jerk here and post images of things done to TS55s non-R for improving dust collection... And a less than happy photo of a TS55 that was used upside down without dust collection. There is one photo here that shows probably why the MT55cc does better (That and without a dust collector as well). The TS55 non-R doesn't have that internal baffling to improve airflow inside the shroud and to pull suction right up to the material. The TS55REQ does have internal baffling (See attachments) but I'm unsure if its configured the way the MT55cc is (Which accelerates the airstream using the sawblade, since the slit between the baffles allows for airflow from the blade to pull the sawdust.) |

I've personally had zero problems with dust collection using the stock hose on my CT26, but the AeroFix hose is exceptionally snug and then you get the benefit of not having to clamp much anymore if that's a thing that interests you.

Forgot to turn the vacuum on with my remote and I started ripping some dimensional 2x with the MT55 earlier. I only realized that the vacuum wasn't on when dust started spewing out.... I turned the vacuum on and nothing happened, pulled the hose out and stuck it back in and the cyclone loaded up pretty quickly for a few seconds. After that and remembering to turn the vacuum on I opened the MT55cc up and here's what it looks like on the insides... Also included: A photo of a TS55(Non R?) that would get me flamed to hell and back on another forum before they close the topic down to prevent a mob lynching. Apparently it was being used as a table saw minus a vacuum. Never had issues with the MT55 the few times I used it without a vacuum but it sure moves a lot of air before you start making a cut... |

Old thread, but there's someone making an adapter for the MT55, to take the new style festool hose end. I have one that he made for the DDF40 and P1 - works really well. Those ones fit over the existing dust ports, this one replaces the original MT55 port. Have ordered one for the MT55, will update when I have it. perfectpaneljig.co.uk/products/mafell-mt55-to-festool-27mm-hose-adaptor |
