Mirka DEROS 550X CV Electric Random Orbital Sander with Case / 5 inch / 5mm orbit/Powerful and Professional Sanding Machine for Dust-free sanding / MID55020CAUS

I LOVE it!It works SO Effortlessly and Quietly it's amazing!I also got the Hose... I would NOT connect to my Ridgid shop vac hose... a visit to Home Depot for a converter kit solved that problem!I also got some Abranet sanding disks and a Pad Saver.I had some very ROUGH slabs of Black Walnut to use as a Test piece.I had some 5 hole H&L sand paper disks.I was started with 60 grit 5 hole sandpaper disks... I was very much surprised how well they worked! ... The vac. got ALL of the dust... NOT a speck! So, if you have a supply of old 5 hole paper disks THEY ARE STILL GOOD!I went through the grits... 60, 80 5 hole paper disks...Then I switched to the Abranet disks... 120, 220, and 400 grits.All went smooth and easy! The super rough Walnut ended up to be as smooth as a baby's butt!The Abranet disks didn't show any signs of wear... a very good BUY for the money!The test piece of Walnut I used was about 14" x 36" and I did BOTH sides!The shop vac was louder than the sander! ... The sander is super quiet... and fits the hand VERY WELL!I did wear gloves that had open fingers... Noticed hardly any strain.I LOVE the sander... I'm glad I wasn't able to get the Ceros (due to personal problems) and went for this Deros when things were better.I had decided I had to get a good sander with EXCELLENT DUST COLLECTION CONTROL because I had a bad experience with sanding without the good dust control... it really messed me up... eyes & lungs... I could NOT go through that again!This sander is WORTH every penny just for the Dust Control! ... It works perfectly! ... I did NOT notice ONE SPECK of uncollected dust!If you are concerned about Dust Control, I'm convinced... This is SUPER GOOD!You will be VERY HAPPY with it!Of course, I could say "For this price, it should be GOOD" ... It is & then some!Thank you, Mirka, for a Super product!

I have had a Merka 5" CEROS for many years & had it repaired a few years back. When it needed repairing again I bought the newer 5" DEROS which I like even better than the CEROS. I would have had a hard time thinking what I would like better than my old CEROS... but the new DEROS is even better. Soft start & very little vibration to the hand. And as always, fastest & best sanding finish you can find. Expensive but worth every dollar if you value your time. Sanding is my least favorite part about cabinet making & fortunately the time spent in sanding makes a wonderful finish.

Low vibration, I can sand hours without vibra-pain. Great cutting action on 35-50grit. Quiet too, don't need ear plugs on low setting. I love this orbital. Quieter than Festool.I purchased a vac tube from mcmaster to attach to my hepa vac. Consistent sanding pattern. I use the backer disc to protect the base disc—it's worth it.I don't use metal screen backing discs anymore—edges frey and scratch your work, even on the name brand discs. Some come with freys showing before use. 2000+grit may be ok to use with very light pressure and watching out for edge frey on the disc. White or Gold oxide discs from SuperGrit are fantastic quality especially for the cost. They last the longest and cut quickly and cleanly with little build up. Diablo doesn't compare—Diablo is trash product, suckering homeowners. Thank God for true industrial suppliers like SuperGrit still in the game! Way to go designing this tool Mirka—you should be Proud—thank you!

I was resistant to paying this much money for such a tiny little tool, and put if off for a long time. But it is really a pleasure to use, very controllable and just feels like its a top shelf tool. So quiet, especially on the lower speed setting, that I don't even use earplugs. Try that with an air tool! In build, its as good as all my Festool stuff. I was wishing they produced one with a 3mm stroke, but I think this 5mm stroke is actually better for what I do, which is to sand and buff nitrocellulose lacquer.

I love this sander. I'm a full time woodworker and have owned a cabinet shop for ten years. I started out with the standard big box store brand 5" sander that cost around $100. It was fine. But after about a year it actually vibrated itself to death. Falling apart from hours and hours of use. I then moved on the the high end Festool brushless 5" sander. It was around $400. It was great compared to the cheaper ones. Easier to hold and it did a great job. But when you sand for eight hours straight you want the best tool you can possible get. So I got the Mirca 5" sander. I didn't know if it would be better than the festool one, but it is. I like the way it fits in my hand. I like how the paddle on the top turns it on and off. It does a good job. After a year of use I think it was well worth the money.Because I sand a lot of sharp edges I use solid 5" sanding disc. Anything with holes gets riped pretty fast. I swear by the 5" Indasa sanding discs. Even though they are solid this sander does a good job of sucking up all the dust. It has ports that get the dust as it comes off the disc.I know $600 is a lot to spend on a sander, but its worth it if you sand stuff for a living.

I'd like to say all the positive reviews are true, light easy on the hands, light, dustless, quiet are all correct. This is the best sander I've ever used. I used it for about 30 minutes the first time. A couple of days later on the second use, it wouldn't turn on. When you power on there is a red light, instead of a green light and it won't turn on. After this happened, I read the negative reviews and apparently these sanders don't last long, which is unacceptable for a sander that cost $625. I also noticed Mirka didn't respond to any of the problems users were complaining about in the reviews, which tells you something. As much as I loved this sander when it worked, I can't say I will try other Mirka product.
