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 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.

Oh I know…it is crazy expensive. That’s why!Given the price it is a big ask to buy. Yet, it is also head and shoulders above the previous Porter Cable random orbit sanders I have been using. The mirka is easier to hold, works faster and causing less fatigue. The long power cable is a very nice bonus as well! Thus, though it is stupid expensive, I would have to say it is well worth it.

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!

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 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 bought this 6” sander in May of 2022. I am a Contractor/cabinet builder. Not full time in my shop. Probably had 200 hours of actual use and the motor completely stop. Light flashes red. It always felt like it was going to vibrate apart. Feels cheap compared to Festool. I tossed it back in the case and maybe I’ll see how much it is to have it repaired. Very disappointing for the cost. Should have lasted for 10 years with the light use I put on it. If you’re going to spend the money get Festool. I like how light weight it is and the paddel. (The main reason I got it.)
