Great product so far
Have only used wine time but so far it feels like good quality did a very job on the wood I was using one thing I did notice was not much vibration on the hands which is nice most sander I have used vibrate the heck out of your hands if you use them for a while
Speaks for its self
I’m particular to this brand I have spent 3k in last two months on stuff with them, so far never any issues. I have dewalt and craftsman and others but selling everything except my Milwaukee!
Great product poor dust collector
Bought this sander awhile ago and love everything about it but the dust collector. Milwaukee needs to design a better collector with a lid that stays on. I ended up using elastic bands to hold the cap in place and seems to help. The vacuum adaptor works well just bulky.
Good sander
Great sander. Need to use a small battery Gets heavy after a while
Milwaukee M18 Orbital Sander
Runs smooth and is easy to handle. I love the variable Speeds on it. Another great Milwaukee product
Very excited about the purchase
Very excited about the purchase and looking forward to multiple ways to used this sander, I can see this being an absolute winner for me moving forward.
2648-20 Backing pad didn’t last long
Sadly the backing pad got destroyed after 3 uses. I purchased this sander 06-07-2025. Wasn’t even using it for too long each time. Can’t seem to find a part number for the backing pad. Am I missing something? This sander works PHENOMENAL and so far no issues otherwise.
Great
Works very well different speeds and last a good while with battery 6
Not that Impressive
I am a huge fan of Milwaukee tools. I was pretty excited about using this tool. But I was not that impressed. First off the dust catcher container keeps popping off and doesn't stay on well enough. I am using it to sand Fascia and trim before priming and painting. It doesn't feel it has more power than my corded Ryobi orbital sander, plus the plastic container for the dust catcher does not go well. Hopefully the Fuel Random Orbit Sander will be better than this one.
Great Sander
Love this tool. Easy to use, plug and play with the rest of my Fuel toys
Another awesome tool
It works great and is easy to handle. Love not dragging an extension cord around
M18 Random orbit sander
Great palm sander !!!! Has a lot of power and is very comfortable for long periods of sanding.
Great sander
I like to refinish furniture as a hobby. I love this sander. It’s easy to use and battery lasts for quite a while. I like that it catches the sanding dust. It’s so much better than dealing with my corded sander.
M18 orbit sander issues.
The sander works well. However, it is difficult to take apart the filter housing and if using it on the ceiling, the filter vibrates off the sander occasionally. I think the filter housing could have been designed a little better.
Great tool!
Very happy with this tool, it does the job it was designed to do, and does it well
Good Sander
This sander works really well. Ive used a few different sanders over the years and this one is great. love that its cordless and starts up and shuts off fast. A 5Ah battery lasts a fair amount with it.
Couldn't be happier!
Very convenient and mobile. The batteries are interchangeable with my other Milwaukee tools.
Best sander in the industry
First sander I’ve bought new and it was amazing that it came free with my m18 drill combo
Excellent
The orbital sander was exactly what i expected from Milwaukee... excellent
The dust extraction lets this sander down
The sander itself works OK but the dust collection is rubbish, firstly it’s a solid plastic constainer with a small paper filter that doesn’t collect much plus the lid doesn’t fit properly and keeps coming off allowing the dust to go everywhere. A bag would be better but I can’t see that Milwaukee do one or a vacuum extractor that fits but again I can’t find one, it would be useful if the web site said if there was one available.
M18 Random Orbit Sander
The M18 Random Orbit Sander only has minimal vibration when using. It’s a huge improvement from my last 5in sander. I would recommend this sander to any woodworking hobbyists.
Great Sander.
Great sander. Battery life is better than expected.
Solid purchase
Exactly what i was looking for. Great power and never bogged down. With a 5AH battery last a very long time. Wished i would have bought sooner.
Sander
Super fast power for quick sanding jobs. Easy to replace pads.
Shop vac compatible
Good sander works great with my shop vac. Seem to last quite a bit on a good charge.
Awesome!
Great product. Definitely recommend. Would buy again.
Superior Power
Superior power compared to Craftsman I've had for years
Superstrong power
The tools is very comfortable and very stronger,this tool works very well,sanding very smooth and clean all surfaces of the wood.
Excellent quality tool.
I needed to replace my old , hand me down sander and i have been systematically switching all my power tools over to the Milwaukee brand. This sander is excellent. Its lightweight yet powerful, comfortable to use and has great features from dust collection to varying speeds. I am very happy with my choice.
Powerful yet lightweight and easy to use!
Powerful yet lightweight and easy to use. The dust collector works perfectly to contain most of the dust. I only have good use of one arm, yet this is easy for me to use but powerful enough to get the job done. Love the 6 speeds to help me control the amount of material removed. This seems to fit any size hands. The universal hose adaptor is perfect for those larger jobs.
Best!!!
Best palm sander I’ve had yet. And I have had many.
Until it gets fixed I would not want another one.
DIY projects but the pad doesn’t stay on at all. Very frustrating. I have all Milwaukee power tools and this is the only one that fails me.
It is versatile tool
This works great the vacuum attachment keep the dust to a minimum for inside work
Super Sander
Best sander I have ever used on refinishing furnature.
Great but 2 in 2 years!
I love this sander, probably because I’ve the set of power tools but it’s great….. but I’ve bought this twice in two years! Last one just packed it in last week, didn’t stop me getting another ? let’s hope it was a once off!
a decent deal
A decent sander for what it is. I was able to find it on a deal so couldn’t resist
100% recommend if you are a professional
Holding the box in line at M&D hardware it felt heavier than my Dewalt sander . Upon opening it and Holding it it felt OK but a bit off balance. After putting a 4ah battery and vacuum hose on it the balance was perfect. Be ware this this has way more power and better orbit than the Dewalt. You can really chew through material fast if using a heavier grit pad. Currently using it to remove a failed drywall texture on a 2'×3' patch on a ceiling. Yes I know it's not the intended use but it's working excellent. I would absolutely recommend this product and I am happy about my choice to purchase it . I'm not at all disappointed.
Wonderful product.
Excellent product! Wish I had bought one sooner. Works great. I’ve got a 21 x 3 belt sander and a small hand sander but they tend to leave tracks. This doesn’t.
Best tool
Fits nicely in hand with very little vibration. Battery lasts quite a while.
M18 Random Orbital Sander
Very easy to use, ergonomics are great. The only problem I have is it is hard to remove the battery.
Sender
Great product and good quality is very easy to work with that and cleaned
Love milwaukee
Great tool at a great price looked around and found it on sales with a battery and charger at Home Depot
Working Well
Happy with all Milwaukee tools so far. This one is no different.
Sander
The sander works great. Light in the hand, doesnt tire your grip out.
Sander 5"
Excellent performance! Better than some corded sanders
I got 3 years of service out of mine and I didn't
Great M18 tool any woodworking project would work better if you have this tool
Great cordless orbital sander.
Like the fact the M18™ Random Orbit Sander (2648-20) is a cordless tool. It comes with a dust canister, an extension adapter (when using high capacity batteries) and a universal vacuum hose adapter which fits most vacuum hoses. It also come with one 80 grit sandpaper. Battery and charger not included which is not a big deal if you have any Milwaukee battery of 5.0 amps or higher capacity.
Best sander ever
Great sander. Works great, has great balance, and the dust collection system is amazing
Dad’s Dewalt
I bought the Milwaukee, because it’s not my dad’s dewalt.
Love It!
I love, my new sander! I can take it anywhere and it’s not nearly as dirty to use.
Great tool
Just got the M18 Random Orbit Sander, and it's a game-changer. Quick, efficient, and cordless. Perfect for my DIY, efficient workflow. Battery life is decent, but I keep spares for longer jobs. Overall, a solid addition to my toolkit!
Nice good value
Good chews up battery quick , make sure you have 4.0
Great sander
It works great. No air line to drag around and sands well.
I Should Have Bought This Years Ago
I don't have the biggest of hands and I have to say that not only is it easy to hang on to it's also fairly lightweight. Only downfall is the different attachments for dust collection, extremely difficult to get off once attached.
This tool is about to get a workout
Long run time and like the dust hopper. Haven't found any issues yet.
Works, but it's definitely not my preferred sander
Could have been great with better ergonomics, but it's currently one of my least favorite sanders in the hand. It could also possibly benefit from soft bag for dust collection so that it could compress down for storage and take up less bulk/weight.
Great!
Very sturdy and feels good in hand! This will be getting A TON of use by me. I have some bathroom projects, and between this and my Oscillating tool (also Milwaukee), there will be tons of use!
easy sanding
works great very fast sanding , dust pick up pretty good, 2 amp battery poor had to use 5 amp or 6 amp to sand trim boards 1x4x6 1x6x8 80 120 150 180 220 full spectrum of sanding 1 inch per second
M18 Orbital Sander
M18 Battery powered Orbital sander that gets it done.
M18 sander
Its a great all round sander and since its a battery powered one its easy to use when you need to go up a ladder.
Smooth sailing
Seems like it will be a good cordless sander. Easy control

Sander
Work's great easy to use and comfortable to use great sander
Happy customer
Works great, battery last about an hour on a 5.0 collects dust very well
Love it but...
Love it! It came a little faulty cause the pad didn't stick. But still gets the job done.
Orbit sander
Great tool needed it to sand places in my pool. Works better with a 5.0 amp battery and up.
Paper won’t stay on the sander
Pad won’t hold paper on. Another one of those the engineers never really use the tool
I like it, but
Pretty good overall, but the dust collector still needs some development. Difficult to tell if it’s properly attached. Still a little heavy as well. Needs to be strong but nimble for sanding.
Work fine
The sander works fine, it can seem heavy when used with the larger batteries so keep that in mind.
M18 Orbital Sander Impresses with dust collection.
Very and happily surprised at the dust collection, even without an external attachment. Dissapointed the provided adapter doesn’t fit my Shop-Vac.
Great tool
I own many milwaukee tools This sander just another satisfying purchase to add to my collection i use it everyday. Love the grip on it lightweight i put a 3.0 high output and get to work.. highly recommend
Would not want another.
My husband got this sander as a Christmas gift. We tried using it the other day. Orbits were so slow even when not touching the piece of wood trying to sand. Couldn’t sand the piece at all. If this is how this jproduct works, want our money back.
Great tool
Great power and balance. Lid for dust collection may pop off periodically, but when snapped on works great.
Super smooth
Only used this for a few projects so far and I love it! Took advantage of a better promo so made it totally worth every penny
Ditch the cord
Powerful and easy to handle. I can plug my vac to it and maneuver easily with good dust extraction.
Orbit Sander Review 10/10
It’s very light, which makes it accessible. It’s also very hand not having a cord in your way when sanding wood.
Milwaukee Orbit Sander!
It has been a great, comfortable sander to use so far. I'm really enjoying it. The battery life and charging unit I purchased are also amazing.
Great sander for the price
The variable speed works great for different materials and the dust collector is universal
Milwaukee rules
Works great, love the ease of use and quick change pad system is very easy to change. The durability is top-notch. Dust collector is very useful and Works very well with the option to hook it up to your shops vacuum system. And I love the ergonomics, helping me fight hand fatigue.
Great orbital sander
Bought this little baby to do some sanding in drywall around our aging renovation
Awesome
Powerful little sander. Battery lasted a lot longer than expected.
Good sander.
Works exactly as expected, great addition to m18 family. Good accessories to help keep mess to a minimum.
Great Sandwr
Great tool. Hooked it up to my shop vac without having to purchase anything additional. Using with sand net pad and produces virtually zero dust. I am really happy with this purchase.
Glides like butter!
Best tool ever will never have a problem with getting the best finish
Recommend for everyone
Great feel in the hand and awesome speed control. The dust collection attachment is handy as collects dust very well.
A must get for a cordless sander
Very impressed. Dust control is great. Well balanced
Mr
Very good compact tool to work with. Recommend this tool
M-18 orbital sander.
It works as I expected. Very handy to have a cordless one. I’ve only used corded sanders in the past.
Amazing sander and design with dust filter inside
I have 6 different sanders and this is my first cordless. It is amazing will be selling the others now !
Smooth!
I read a handful of reviews before purchasing this unit. Contrary to what a few people said I had no problems whatsoever. The sandpaper stuck to the pad with no problems and it got the job done.
Okay
Non vacuum dust collection is poor. Depletes batteries rapidly. Can only compare to hand sanding and its not as big of an improvement as I had hoped.
Why didn't I have this before?
Mighty little handful of power with adjustable speeds, coupled with differing grit grades, it's like it can go anywhere/do anything. Just be prepared to have 2 ea.5-6 amp batteries and a charger in one carry case.
Good value sander
With a shop vac connected to it sanding drywall ceiling is a breeze. Efficient and lightweight
Bulky
I think the tool is too bulky when you attach the dust filter.
Great tool!
Great tool, very easy to use. Can achieve a lot with this. my only issue was using the 1.5v batteries with it, they drain pretty fast. Besides that, good product so far!
Very Compact and Powerful
Very compact and easy to use. I am a big fan of the Milwaukee cordless power tools.
Great Sander
works very well - nice sander -easy to handle and does a great job - runs batteries down pretty fast
Cordless tools are great!
It works great and your not having to work around a power cord
Best tool I've ordered
The sander works great and it's ergonomic feel is just awesome
Great tool
It is very powerful and does the job very fast, it has multiple speeds which comes in handy when doing a tough or easy job. Easy to grip and attach the disc to. Ideal for both beginners and median experts and DIYers.
