I most humbly apologize - thought the only option was using the 27mm hose and I didn't read Tom's post closely.

Thanks for setting me straight.

I purchased the HSK 80 x 130 Hand Sanding Block (496962) thinking that a block with DC could be handy even around the shop. I have become so accustomed to not having dust in the air when sanding that I now even notice it from small hand sanding jobs. Even from just cleaning up board edges. The 80 x 130 seemed like the size to get since it is about the size of most traditional blocks. It also uses the same abrasive sheets as the LS130 (which I already had) and the RTS400.

I also got two different hoses to use with it. One Anti - Static (456745) and one Non- AS (495019).

The block is a nice size with a well shaped grip.

Thanks Seth for the write up on HSK 80 x 130, hand sanding can be just as dusty and hazadous to your health as using a power sander so this is really on my list. I'll be getting the 21.5 hose as well. Too bad i don't have a sander with a 80 x 130 pad though, means I'll have to buy paper especielly for this application.. or else make a template and cut my own..

This block sander is the small Mirka sander rebagded in Festool trims, so the Mirka products work and fit the Festool sander. I have had mine for sometime now and could not be without it. Both will interchange pieces and parts and papers. Peter Parfitt has a wonderful piece on his site, check out his sanding dust in the workshop, quite inlighting and should be seen by anyone who is near a woodworking shop, by that I mean loved one who maybe breathing the air in the home with a shop even near it. I have brought dust and other dangerous thing into my home without thinking and harmed my wife. Once was enough to teach me to change my ways when it come to dusts, my wife has a breathing condition that is harmful to her. So think about where the dust is going and where it is landing, and get good DC products like the Festool and Mirka. B

Funny you should mention this piece, Seth.

We just broke it out this week and stuck synthetic steel wool on it for a super fine scrub down prior to our final satin coat on the cherry table we are finishing.

Gotta love a tool that is equally useful and wood and drywall.

Although the Mirka and Festool vac sanding blocks look very similar they are a couple differences that make the Festool far superior in my opinion. Having used both for drywall the Festool has a built in interface pad and accepts the RTS paper meaning you can also use the interface pads for the RTS on the block. Also the base of the block has tapered edges that don't rub against adjacent walls if your sanding a corner. I didn't like the abranet at all for drywall as it leaves linear scratches in the drywall because of the waffle pattern. I do use the Mirka hose though as it I already had it but it looks pretty much the same as the grey Festool hose.

I have the Mirka one, BUT has anyone tried Festool with the CTL SYS yet? Since the suction can not be adjusted, the CTL is struggling like as if I blocked the airflow. Would gladly change to the HSK Sanding block and hose (since it is slightly wider in diameter). Let me know if anyone knows.

Does the hose you are using have the suction let off at the end? That would help. Though I find that I often use both the let off and turn down the suction.

The Festool version comes with this little valve shown below. You can adjust the suction as you see fit. However, using a CT 22 on max vacuum and with the valve opened fully, there is still enough vacuum to adhere the HSK to a vertical sheetrock wall. Not by much, but it will stick lightly to the wall. That's the reason I turn down the suction on the CT 22 and then use the in-line valve to "fine tune" the amount of suction.

andreasg · « **Reply #68 on:** May 22, 2015, 10:29 AM »

Well, i might help, but it's an issue even with just the hose. Without the sandingblock. Probably cutting off some length would help. I will test taking off 1 meter/40 inches.

Or how about they just upgrade this product with a possibility to adjust:)

A little on the fence on wether I return a Festool product for the first time or not. Need to try with a couple of electric sanders too. I never use full suction with those and my Midi either.

Peter Parfitt · « **Reply #69 on:** May 22, 2015, 12:12 PM »

For anyone using the Dust Hub or something similar of their own, you can have a bit of extra air going in by opening an unused blast gate by a small fraction until you are happy with the noise from the CT or the suction obtained.

I have used this method with my Abranet hose and pad.

Just for information's sake, Bosch has a hose that works as well. I don't know the # as I have had them for years.

andreasg · « **Reply #71 on:** June 03, 2015, 05:28 AM »

Thank you for your answers and suggestion. I´ve decided to return the CTL Sys. Not an easy thing to do, love the concept!!!!
But this is ment for small jobs, and the lack suction-adjustment is too big of a drawback for me.

If this issue will be solved by Festool I will for sure run back and get the updated version!

Can the valve be removed from the sanding block and being used for the ctl sys and f.e a rts 400 to have suction control?

The valve section only fits the 21.5mm hose. So , no, not with out some sort of home made adapter.

Seth

Marcel71 · « **Reply #74 on:** August 08, 2015, 03:46 PM »

Seth, thanks for your reply.
Sounds good for me
So the adapter is removable and fits a 22mm hose.

So if i'm right and buy the sanding block and can use the adapter in a 22mm hose and connect to my sanders.

That sanding block is on my wishlist for a while

@Marcel71 No. The sanders have a fitting for the 27mm hose not the 21.5mm. You would need to make something to make the valve from the 21.5mm sanding block hose work on the 27mm power sander fitting.

Seth

Marcel71 · « **Reply #76 on:** August 09, 2015, 12:00 PM »

Ok thanks, i'm gonna figure something. I'm gonna buy the sandingblock anyway

Maybe ,when I got my sys ctl, I open it and take a look if I can build in an electronic speedcontrol myself.

Right I meant the 21.5mm gray sanding block hose in the posts above (changed them). But the valve won't fit the power sanders. Pretty sure it comes with the sanding block not with the hose.

I moved the valve to my grey hand sanding Festool hose , works well that way, all that's left on either my Mirka or Festool hand Sanding blocks is the plastic port which connects to the valve/hose assembly. The valve always stays on the hose too, doesn't work off when you remove the hose from a sanding block, which I think is pretty cool.

jobsworth · « **Reply #85 on:** September 07, 2015, 04:54 AM »

Has anyone used the valve on a reg Festool sander like the RTS400 or RO 90'etc, I wonder if it will eliminate swirl marks better then just lowering the suction

Well Mirka is either Finnish or Norwegian, but they could be make in China and maybe the FT ones are also from there... I dunno.

If you already have FT media then FT is probably best.
However I ordered a Mirka one over the weekend and I already have some of the abraidenet.

I was using the abraidnet on a 1/2 sheet sander and was surpised that there were swirl marks on the wood.

I think that the Mrs had put on a 120 gr screen.
I chucked on a 240 and it was BB smooth.

I like the Mirka much better than the HSK, mostly because the hose is so small and manageable. I will say that I would prefer the Festool if they had a small hose because I have a lot of that paper on hand.

AAAbrasives.com has Abranet for prices comparable to the Festool abrasives.

Anyone tried this lightweight hose for electric sanders? We´re told to turn down suction to halv anyway. Just curiuos, since often the weight of the hose "messes up" the balance of some of the tools. And just got a reminder of this issue since I´m gonna give my ceilings a small "rub" with a sander before painting. Don´t have the 150 ec ets yet, but it´s probably next:) It´s a light one, but up on a chair with 8 feet of hose in the air, that changes a little.

Which Festool hoses are you using for comparison? There are two that are specifically recommended for the hand sanders...

The most popular by far in my experience is a 21.5mm x 5m hose that is pretty flexible and friendly. It is non-antistatic but I don't think that's a big issue for most climates with hand sanding.

The other option offered by Festool is a 22mm x 3.5m antistatic hose. It will be significantly stiffer but depending on your climate, you may like the antistatic properties enough to prefer it. These antistatic hoses are currently limited edition items because they were discontinued in North America...

Kind regards,

Tom

That is the gray one in the review. It is extremely light weight. And very flexible as can be seen in the pictures.

Has anyone tried to modify the HSK for use with LS130 pads? Would it be possible to get the pads working by attaching the "489504 base plate" spare part from LS130 on the HSK (using glue or another creative solution

)? Does the LS130 base plate dust extraction holes line up with the HSK holes? Anyone with both LS130 and HSK would probably see if this is possible by looking at the base of the LS130.

neeleman · « **Reply #89 on:** October 19, 2015, 05:44 AM »

Yes the holes will line up with, because they both use the same sandpaper.
But you'll also need the spring load mechanism of the LS130 base plate (490302).
