Mirka DEROS 550X CV

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 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.

Lught weight but very powerful. I'm 260 and can lean right into the sander and it keeps on turning. Feels really good in your hand

This tool has changed my shop life. I had been suffering from what I can only assume is carpel tunnel in my wrist from working in general, and exasperated by sanding. I was using a DeWalt prior to being turned on to the Mirka, and it was awkward and heavy, making sanding while suspending the tool in the air (like sanding the edge of a board) painful, especially after a long session. This sander is incredibly light in comparison. The center of gravity is quite low and it is compact, making it easier to keep flat on the workpiece as well as making it more maneuverable. The vibration from this tool is so minimal that I no longer need gloves, and it is impressively quiet. I used this sander for about 6 months under heavy use, and inevitably an electrical problem occurred (I actually live in the rainforest where humidity is stupid high all year). I sent it back to Mirka with a brief explanation of what happened and how I hoped that they could repair it for me. Within ten days I had a brand new sander in its own new systainer box and all of the original accessories that came with the first one. Not only is the tool itself impressive, but their customer service and warranty is top notch.

I have owned and used a variety of orbital sanders through my woodworking career and this one tops the list. It does the work with ease and little vibration. Super product!

So very disappointed in Mirka. Sander quit on me after less than 8 months. Flashing error lights and shuts off after two seconds. It was well within warranty, and the tool was registered with proof of purchase, so I sent it in for a warranty claim. I was shocked when the warranty claim was denied because of 'normal wear and tear' It's normal wear and tear for the sander to quit working after 8 months?!? No other explanation was given. I asked what was the normal wear and tear that caused the sander to quit working and was told I would receive a response from the service center. I didn't receive a reply and over the next several days I followed up 3 additional times and was eventually ignored completely. I have two weeks to decide to pay the repair or they will send it back to me with the tool possibly disassembled. (I kid you not, they cannot reassemble the tool if they have had it taken apart due to 'safety reasons' I am now stuck with a very expensive sander I am forced to pay repair costs on. I own 4 mirka sanders, (3 of these electric and one pneumatic) I used to recommend Mirka to EVERYONE, now I am considering trying out the knock off sanders on here. I can't get worse service and can purchase almost 4 of them for the price of this sander. I am SO surprised such a premium tool has such horrible support and customer service.

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!

This sander was the first big investment sander I made as a hobby woodworker. I had high expectations, especially given the price, and it had some benefits. It's very light and versatile and is a great random orbit sander. It falls short on heavy sanding, where you need to take a lot of wood off. It did attempt it, but just wasn't more than a really good random orbit sander. I kept it for a few weeks and had to send it back. I replaced it with a Festool Rotex 125 for the same price and am very happy with the Festool.
