Author Topic: HSK 80 x 130 Hand Sanding Block and hoses (Read 127186 times)

SRSemenza · « **on:** July 28, 2013, 01:06 AM »

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.

In some ways this review is more about the hoses than the sanding block. Suffice to say that the block sands as it should

---------------------------------------------------------------------------------------------------------------------

This picture shows the D27 , D22 AS, and D21.5 (D22) non-AS hoses side by side. The block can be used with any of these. There is a significant difference in outside diameter of the D27 and the D21.5 as can be seen in these pictures.

--------------------------------------------------------------------------------------------------------------------------------------------------

The non-AS 21.5 can be attached directly to the sanding block air control fitting as shown in the first picture above.

The D27 and D22 use a rubber downsizing adapter to allow the regular hose connection to fit the block port. The AS D22 could be attached directly but the fitting is loose in the hose and would need to be built up with a couple wraps of tape.

-----------------------------------------------------------------------------------------------------------------------------------

The best hose to use with the block is the D21.5 non-AS. It is really light weight and super flexible. It hardly was a hindrance at all. The following two pictures are to show the flexibility. One thing to note is that this hose does not come with any tool end connector. The connector comes with the sanding block, and has a suction let off built in. I found that it worked well about half way open with the vac (CT33) set to about 2/3 power. This hose is very light weight and thin walled is obviously intended for use with the sanding blocks. I would not expect it to hold up well to a lot of abuse such as crushing or being folded into a crease / kink. I am not going to test its durability to the breaking point. It should be fine for its intended use.

--------------------------------------------------------------------------------------------------------------------------------------------

The D27 is OK in a pinch but quite clunky with the regular hose connector, not real flexible and really too heavy.

-----------------------------------------------------------------------------------------------------------------------------------------------------

The D22 AS is just about as clunky and heavy feeling on the block. It is a little more flexible. This is an interesting hose in that at the vac end it starts out as a D27 and gradually tapers to the D22 at the tool end. I actually think this might be a good hose to use with jig saws.

------------------------------------------------------------------------------------------------------------------------------------

Here are a couple in use shots. It was nice to be able to give a light hand sanding between coats of laquer on this piece without having laquer dust in the air.

-----------------------------------------------------------------------------------------------------------------------------------

It can also be used very nicely with interface pads for roundovers and such.

I purchased this mainly for touching up some drywall plaster external angles on our owner build, once the plasterer and I had finished the overall sanding. It has worked well for this, although I agree the larger diameter hose is restrictive.

I have found that the vacuum should be turned right down and the gate on the connector left open to prevent the pad being sucked too much down on the work.

I am yet to use it on wood, but Seth's review offers new horizons to all who want to sand by hand dust free.

Bikeboy80 · « **Reply #2 on:** July 28, 2013, 07:35 AM »

I love my hand sanding block

I was using it this week to sand putty marks on new installed baseboard before paint.

You're right it works with the larger hose but it does take a bit of moving around to position the hose.

Where did you pick up the 21.5 hose?

Gone · « **Reply #3 on:** July 28, 2013, 07:48 AM »

Good review Seth. My son and I have been using the Mirka version of the sanding pad for 2 years now. The son has done a lot of drywall with the block and found it to remove the dust very effectively. I have 2 with different grits that I use all the time in the shop. You would be surprised how well the hoses hold up over time. The vacuum adjustment valve on the Festool block is a nice touch. Might have to buy another block to get the valve.

The vac / suction setting I used worked for what I was sanding but I am sure it would have been too much on larger flat surfaces.

On second thought the hose is 5 meters long I can spare a few inches to test it to the breaking point.

Folded over tightly and worked back and forth a few times.

After .............

-------------------------------------------------------------------------------------------------------------------------

After being ground on the concrete under my work boot heel.

--------------------------------------------------------------------------------------------------------------------------

That's a K-Body as tight as could crank it.

After...........................
Then worked back and forth about 20 times to see if it would crack.

-----------------------------------------------------------------------------------------------------------------------

And lets get serious.

After ...........................

-----------------------------------------------------------------------------------------------------------------------

A little worse for wear but it never ended up with any holes , and I was able to squeeze it back to round and use it. Nothing scientific here but it turns out that the hose can take some abuse after all.

That 'kit' is how we here in the USA saw the blocks for years when they were NAINA.

For my purposes, I don't have a need for the long and narrow sanding blocks that are available and part of that kit. I'm much like Seth in that I bought the smaller block, and I already own that size abrasive for the RTS400 and LS130 sanders.
I also bought the RS2 sized block for larger work, but fully expect that the small block will be my most used out of the two.

I don't think the kit is available here. I probably would have passed anyway. I don't for see using anything but the small one. I But I would buy others if the need arises. Most likely the 115 x 226 would be next. Just depends what you do and how much you like hand sanding.

There are four of them sold here but I'm not aware of any kits.

One uses the same paper as the LS 130 or RTS 400, one uses the same paper as the RS 2, and the two others use special-sized paper. It is 80mm x 400mm with perforations to make it into two sheets that are each 80mm x 200mm.

Maybe I should have set "set" instead of "kit". In Oz we can get all four for $AUD350 at the moment.

Well hey now, look at that. A Sys- II holds the 5m hose perfectly

I may not keep it in a Systainer. I want this to be handy so it will probably be kept hanging near the vac , ready to use.

And the attic compartments will hold the 80 x 130 abrasives just right

Yah, pretty sure it will melt.

But seriously I am surprised that it took that much abuse without cracking or getting a hole. Because it is very thin and light weight.

I think Granat and Brilliant 2 work well for this application . Abranet may get some clogging, but with the coarse to medium grits, it's not as likely as using their 320 and higher grits.

It should collect the dust quite well. As far as the abrasives go I have never used any of them on drywall.

None of the LS130 profiles, or attachments fit. It just uses the same size abrasive sheets and the interface pads also work. That would be nice if they did fit though.

Hi Seth

I wish that kit like this was easier to find on the various Festool web sites. It is almost as though you need to know a bit about a product in order to be able to find it. Try going to the sanding section of any Festool web site and see if you can spot these items - they are not there.

I have been using the Mirka/Abranet equivalent and now want to try this.

Many thanks for doing so many test on the hoses - I think that it was a good part of the system to focus on as I have damaged small hoses like this from other manufacturers which then ruins the investment.

I bought this for drywall. I found that if I sand in a circular motion I can get a really nice finish. I use the 150/5 on the first coat, and this on the subsequent coats.

No regular tool end for the gray 21.5. But maybe you could cobble one together. However it would not be anti-static.

I have had my Mirka block sander for about a year and it has a valve on it near the hose attachment point. Mine may be different model, but you may want to check. Brent

My Mirka block has it too, a rotating sleeve on the back of the block opens or closes a port.

Good review Seth. My son and I have been using the Mirka version of the sanding pad for 2 years now. The son has done a lot of drywall with the block and found it to remove the dust very effectively. I have 2 with different grits that I use all the time in the shop. You would be surprised how well the hoses hold up over time. The vacuum adjustment valve on the Festool block is a nice touch. Might have to buy another block to get the valve.

Thanx guys my latest Mirka has the rotating sleeve, I have 3 now, the original sander was given to by a Mirka rep, along with hose and a roll of paper. Totally impressed me. Can't beat the price either. Sorry Festool.

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.

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,

Hi Tom,

The Mirka hose is 3/4" vs. 27mm for the Festool.

If Festool offered a comparable hose or a whip I'd buy it.

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.

Seth

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

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.

@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.

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.

If you already have FT media then FT is probably best.

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

I'm thinking of making my own HSK 93 X 175 using a stick fix pad for the RS 300 EQ, my abrasives are all for this sander and I'm not interested in getting the 80 x130 size. I would make the bulbous top piece out of wood, and the suction section out of some suitable plastic material. The only thing missing would be the valve for controlling airflow.. that wouldn't be hard to rig up..

So I'd just need to buy the Stickfix pad, 21.5mm hose some wood for the "handle" material for the suction section and the valve. It won't be cheaper to make than buying the Festool block but will save me a bundle in abrasives..

I use mine on flood repair projects and did so today to sand down the drydex (sparkle) filler I used to fill/smooth out new MDF casings mitre joints, after I glued the mitre joints with 2P10 adhesive.

Makes for quick work and minimizes dust contamination to the work area (not 100% and that's okay as flooring has been disposed of)

Thanks to Seth and all of you who answered my question. I plan on trying it instead of the RTS400 to sand a few small drywall ceiling patches to see how well that works. It looks like I'll be finding lots of other uses for it down the road.

I grabbed one to sand some drywall touch ups while repainting our bedroom. Kept everything nice and tidy. Even the wife thought it was great!

I added the interface pad for blending patches into the surrounding wall. The set up works great for the smaller stuff. Most of the mess is either contained or falls straight down rather than floating across the house. Love the small hose Seth recommended too, very light and flexible with more than enough length to allow me to work my way around a bedroom without having to reposition the extractor.

Instead of a smaller hose, I like to use a router speed control on my rigid shop vac when using my little Festool hand sander. Works great. My dust deputy gets most of the dust but the key thing is the dust doesn't go all over.

In a pinch a 6 inch disk and a hole punch will cover almost all the bottom. Sometimes there's a grit that I want that's "outside the box"

Seth, great review especially the hose durability test. I'm alittle shocked you haven't made block sander and hose /accessories fit neatly into systainer. What size sys would it all fit into?

Well hey now, look at that. A Sys- II holds the 5m hose perfectly

I may not keep it in a Systainer. I want this to be handy so it will probably be kept hanging near the vac , ready to use.

And the attic compartments will hold the 80 x 130 abrasives just right

Do you think it would be possible to use a SYS-I for the hose or would that be way to tight?

JimS_1984 · « **Reply #106 on:** April 26, 2016, 10:20 AM »

SYS-1 will be too tight. I tried putting the 21.5mm hose and HSK-80-130 sanding block in a SYS-1, but had to move up to SYS-2.

Have a picture to illustrate, but the attachment is failing.

Once more...with feeling:

HSK 80-130 with 21.5mm hose in a SYS-1.

So yes, it's too tight. SYS-2, on the other hand, will hold it comfortably,and is easy to pack-up.

I will probably go for the SYS-II with lid compartments then.

I ended up putting my 21.5mm hose, and both my 80mm-130mm and 115mm-226mm hand sanding blocks into my empty SYS-3, that my 3.5m sleeved hose came in. Still room for a small supply of abrasives as well.

Reviving this old thread as it's incredibly useful for what I'm looking at! The main reason I'm looking to use this is to keep dust from sanding between Primer/Paint coats (SW KA+).

For those who used it, I have a couple questions

1) Do you think that I'll still need to go over this with a microfiber cloth if I use the vaccum attached hand sander or would that be enough?
2) Would the suction, turned all way down on Midi and port open on this cause too much suction for a sanding between paint coats?
3) Is this as helpful on normal woodworking projects or mostly other uses?

Thanks everyone!!!

I don't know specifically on that paint. But the suction as you describe should be fine. I do think you will still need to vacuum or otherwise go over the piece again to be sure you get as much dust as possible off the surface.

After using the hand sanding blocks, I go over the sanded piece with this:

I also think it could not hurt to use your microfiber cloth just to make sure you get all the dust.

Hello,

I am planning on getting the HSK 80 x 130 with the D21.5 hose to sand multicoats of water soluble varnish with grits from 240 to 600. Festool only sells the abrasives in packets of 50 which is far too many. Has anyone used the Mirka Abranet 80 x 130 abrasives with the Festool hand sand block? Which abrasives are preferable?

Yes, before I could buy the Festool Sanding Blocks, Mirka had theirs for sale here in the US, so as long as the size is right for Velcro Abrasives between the two brands, it all works. I've used the net type/mesh type abrasives from both Mirka and Festool for 'between coat' sanding on Film Finishes. I typically don't go above 320 grit so the next coat has something to 'key into' versus being too smooth from sanding to adhere easily.
Both Regular and Heavy Duty work fine for that type application, it would come down more to what price you want to spend and how large of a box you want to work with. As an aside, some Festool dealers are willing to break down a full box of abrasives to a certain number, say like a 10 pack, for Customers- Ask, you won't know until you try...

Re-reviving this thread, I picked up the block and 21.5 mm hose thanks to this thread.
Since I didn't pick it up until a week ago, now the new Systainer³s are out, and we know that they're sized differently.

Not knowing how much spare room was in the SYS-II TLoc, I took a risk and ordered a Sys3 M 137 to see if things would fit.

To my pleasure, they fit like a glove in a Sys³ M - 137.

If you need more room, the 187 is the next size up, and slightly larger than the old SYS-II TLoc. It should be more than enough room for the block, hose, and I don't know what else.

Also, I didn't think the non-AS hose would be that big of a deal until I walked over and bumped into the washing machine after sanding. Yikes! Still worth it for the ease of use of the setup.

I'm struggling getting this HSK 80 x 130 connected to the hose of the CTL MIDI-I which has should be the Ø 27/32 x 3,5 m-AS/CTR hose, the converters that came with the HSK 80x130 itself are too small and the rubber ring around it does not fit the MIDI hose.

Is there any connector/converter that I'm missing or should I try to get that D21,5 hose somewhere? Prefer to have a converter/connector though.

Hi,

I just tried it with the new style 27 connector. I got it to go on the reducing ring. But it is an extremely tight fit. It is tight on the old style but even more so on the new.

I did a quick internet search and the 495019 hose is still available. If you plan to use the sanding block much at all, then you will appreciate the much lighter hose.

Seth

Cheese · « **Reply #123 on:** May 08, 2022, 12:06 PM »

I'd echo what Seth suggested especially if you're using it vertically or over your head. The weight of the heavier hose wants to constantly pull it down. I managed to attach my HSK 80 directly to the older style AS green hose and the operation was clunky on vertical surfaces.

The only drawback is that the 21.5 hose is non antistatic,

so if you bump up against something that's grounded, well, you'll be subtly reminded.

afish · « **Reply #124 on:** May 08, 2022, 04:17 PM »

I dont know why but none of my hoses are anti static and I have never gotten one shock plus I have about 50' of pvc. I live in very high humidity location so not sure if thats why but it seems odd while others have issues.

I just received this sanding block, and the vent is extremely difficult to turn. I was able to turn it with a lot of effort and time but I don't think I'd try it again without gloves. I remember a review mentioning it moved too easily, so I'm wondering if Festool over compensated. Regardless, should I keep it anyway because I won't need to adjust it very often if at all?

Is the vent necessary if you can adjust the suction at the DC?

My valve stiffens up considerably after it hasn't been used in a while, so when I need to grab a pliers to turn it, I instead lightly lubricate it with DynaGlide and that's all it takes.

I still use the vent even though I'm using a MINI, MIDI or CT 22 because the vent is on the tool and I don't have to walk 15 feet to adjust the suction of the vac.

Good to know. I just removed the valve from the block (required vice grips) and now the green collar will turn. I'll try lubing it and reinstalling.

Edit: I applied a drop of oil, and I can rotate it by hand now. Thanks for the suggestion.

I haven't used mine in a while so I can't confirm the setting up over time. But Initially I found it was way too loose. Kept accidentally closing it. I ended up taping mine open. I have never wanted it closed at all even with vac suction turned down.

I have had the slightly smaller Mirka version of this hand sander for a few years, and use it with Abranet mesh.

Originally, it was used with the 27mm Festool hose, but I found this to be too bulky and heavy. I purchased the 22mm Mirka antistatic hose, and this is night-and-day different .. and so much better. It fits perfectly into my CT 26e vacuum cleaner.

I have a new LS 130 that I still need to fire up. Should I add this hand pad since it uses the same papers?

How hard/soft is the pad on the HSK? I hope it's pretty hard, as one can always add interface pads to soften it.

Right now I use a dense cork sanding block, to which I've added some hook backing to try out. Cork blocks are great for hand sanding, except for dust.

It is what I would call medium hard. It has a bit of squishiness but is also thin so starts to compress against the hard plastic block with out much compression. Compared to a Festool power sander pads I would say it falls right in between hard and medium.
