Does the Makita LS1219 really have better dust extraction than the 2019 Kapex?

What about when you mate the Kapex with a 36mm hose?

I only mention the 36mm hose because it is not assumed with the Kapex dust collection reviews I have read.

 I notice Festool now specifies the 36mm hose in their latest dust collection stats on the 2019 Kapex.

I am more interested in knowing if the substantially less expensive Makita LS1219 out preforms the Kapex in this area.

I have read opinions on both sides.

Everything that can take the 36mm hose becomes better with dust extraction compared to the 27mm hose. Eg TS55, OF1400, EHL65, etc.

I don't own either mentioned saws though, so can't comment on that.

I own the router and the TS55 and and also attach to table saw and I recently upgraded
To the 26 vacuum with the 36 mm hose.   Wow what a difference.    Hope this helps

Both saws are likely far better than anything else available, but determining the "best" may depend on how you define best.  Some might say "give me the saw that captures the most wood in weight".  Others might say "give me the saw that captures the stuff that gets airborne, I'll vacuum what falls under and behind the saw".

Theoretically speaking, the Makita splits the vacuum line to go to two boots, one behind the blade like the Kapex and a larger fixed one behind the fence.  This should capture some of the course particles that land behind the fence on the Kapex, but splitting the airflow probably means more of the fine stuff will escape from behind the blade and end up in the air.  The Kapex directs all the airflow to a single boot behind the blade, however, even with a 2m x 36mm hose some fine dust still escapes.  So even if the blade encapsulation and boot was identical in both saws, knowing the Makita has to get less airflow to the boot behind the blade, I would gamble even more fine stuff escapes.

Where do I find a 2m 36mm hose? I searched for it yesterday for several hours and could not find a custom hose.

Airborn dust is my main concern.

I improvised and used a section of the pool hose from Lowe's for the Kapex, like this kind: https://tinyurl.com/y3rxhaj9

The hose as is was slightly too small in its opening, so I used a Dremel with a sanding drum to enlarge the inner tube. Of course, the pool hose is stiffer than a Festool hose, but only at a fraction of the cost, and you'll have some 25' left for other uses.

I also bought an extra dust rubber shroud and use it for certain cuts (MDF, e.g.) with a stache like this:

If you're located in Canada, I can send you a length of the hose to try out.

Thanks this got me looking at other options.

I bought the 36 mm Festool hose for my new Kapex, but did not have the stomach to cut a 175 dollar piece of hose in half and dedicate it to the Kapex.

I just received the 33 dollar Bosch hose from Amazon noted above and it is a nice flexible hose.  The ends twist off and on easily, so shortening it was a simple job.

One end fits my CT 26 nicely, and I did a small bit of surgery to make the other end fit over the vacuum fitting on the saw. 

As an aside, I bought the new model Kapex from Tool Nut.  Tool Nut was great and I am loving the saw :-)

The Bosch VAC005 is exactly what most here use.  You can also order the Festool 36mm fitting for non-antistatic hoses and it will screw onto the end of the Bosch hose.  It' been a while since I did it, but I believe the fitting on the Bosch hose chokes the airflow unless you do some surgery like Warren mentioned.

I have the cordless version of that Makita saw. It too has the two port arrangement. What disappoints me is: 1) there is maybe 3/8" straight length to fit a vac hose on the port until you run into some stiffening ribs. 2) I didn't measure it but the port must be 2" in diameter if not less!

I ended up purchasing one of those Rockler  silicon adapters.

EDITED: Interesting, just noticed the LS1019L has the vac port at the lower DC junction facing downward like it should. The LS1219L and my battery unit it faces upward and it's on the top.
