Asked by Hector15 November 30, 2020

I have use mine as for now in drywall and wood finishing surfaces and it works great, also sanding heavy textures in walls and ceilings. I would recommend a different sander for that element.

How cam I buy sandpaper for this Random Orbit Sander ???

Asked by Don November 28, 2020

I was not able to buy correctly configured sanding pads at the store. They only sold the Diablo pads, whose holes do not match those of the sander. Because they don’t match The suction of the vacuum through the pad did not work well at all. I was able to find 5 inch pads on the Internet had a very good price

Terrific sander
I purchased this to sand and re stain my post and beam shed as I did not want to fight with a cord while on a ladder. The charge lasted a surprising amount of time as it took me a few days to get it done. I regret not buying one sooner.

Sander works just fine, its the flemizy attachment that connects vacuum hose thats terrible
There is a grey/clear plastic sleeve that slides over the sander receiver on one side and the other part of the sleeve connects to vacuum fitting. The amount of stress placed on this flimsey sleeve is fairly significant when the vacuum hose is added. Very poor design to say the least. Anyway it split on both sides in a matter of seconds of use. Hand to improvise with 100 mile an hour duct tape. Looked everywhere for a replacement but nowhere to be found. I really like and enjoy my Milwaukee tools and i have bunch. This has been the only one so far that i have found to be cheaply built.

Good dust collection and power
Got this as a "free" tool with a battery and charger kit. Been looking to replace my old corded sheet sander with a cordless random orbit sander and this did no disappoint. Sander comes with two sheets of 80 grit sandpaper, dust collection unit, extension for the dust collection and also a shop vac hookup. Sander is variable speed so that's very helpful when sanding different materials but I generally just leave it on the lowest setting. Feels good in the hand, allowing you to either grip the top or grip the side. Thought was put into creating the dust collection as it comes with an extension piece so if you use larger batteries you will still be able to fit it properly. Although with the larger batteries it will essentially weight as much as the tool bare so while large batteries will provide a good run time, the weight is significantly increased, even with a 6ah which I used with this sander. 3ah will probably be the sweet spot for weight to duration. Slight downside, I had the disc itself get a bit squeaky when slowing down becaue there was dust trapped between the unit and the oscillating part of the unit. So i had to remove the sanding pad and the unscrew the hook and look part to clean out the other side of the tools pad. It still worked perfectly fine throughout but I just got annoyed with the squeaking sound when I turned off the sander. Overall a great product, sands very well, dust collection collects a large majority of the dust and price is equivalent to other brands out there while providing a higher quality sander.

Best Sander Period
I sanded my entire car from factory paint to body filler , epoxy primers . I’ve even used this sander wet sanding with great results. I have other sanders but they seldom get used . When I need sanding done M18 orbital is the one I grab!

Wish I never switched
I switched from dewalt once I started seeing my friend buying all the m18 fuel stuff seemed a lot better so a few months ago I made the switch I wish I never did and it has caused me nothing but time and wasted money I’m on my 3 rd fuel drill set my second multi tool and the 2 month old sander just stoped working I will probably never buy another tool and look for a better platform there tools are not worth the money if I could go back in time I would keep my xr/ flexvolt stuff and never switched when u use and rely on these toools to pay your bills it is important to have a reliable tool Milwaukee just Is not that and way over priced

Dust flying everywhere
I buy all Milwaukee m18 tools and have for 3 years now.. proof on youtube ( 1806 stone house ).. this sander is not worth the money.. unless you want to put duct tape over the dust collection to keep it from falling off....very disappointing
by Stone House
Large and unwieldy for all but big flat surfaces
Full disclosure, I'm a small-time DIY who likes to buy quality tools so I only have to cry once. I'm not in the trades. I had recently purchased another company's cordless sander and used it on a DIY yard project for about 20 days when I came across the Milwaukee sander and a tool kit at a decent price. Milwaukee is a much higher quality brand than the "other brand" I had purchased. I returned the other brand as some of the tools had small issues that were causing me concern, and I picked up the Milwaukee set. I already own a handful of M12 tools, so this was my step up into the M18 platform (with a 7-tool set + the sander as a separate purchase). There is no doubt that the Milwaukee sander is better built than the previous one. However, it may be overbuilt for my preference. After continuing the project with the Milwaukee M18 Random Orbital Sander, I find myself wishing for the other one! The reasons I like "the other one" better than the Milwaukee, even though it's clearly not as nice of a tool: 1. The Milwaukee tool is too heavy, even with a 3.0 XC battery. I find that by the end of a very small sanding job, my forearm is tired. I was doing 3 times the sanding with the "other one" and never got tired once. This thing is a big, heavy beast. 2. The grip is uncomfortable. It's hard to describe, but the way the palm rest is designed, my fingers have to curl under it and "pinch it" to hold it. With this big heavy beast running, it really just doesn't feel good to have to pinch it to hold it for so long. 3. Again, due to the size, grip, and weight, doing anything other than sanding on a large flat surface becomes uncomfortable fast. For example, when cutting a bunch of 2x6's to length, I like to sand the cut lines to remove any splinters or tears from the saw. I hang the 2x6's off the sawhorse and I have 10 surfaces to sand (4 edges of each side of the cut = 8, plus the two ends). That's a lot of holding this sander one-handed at regularly changing angles. If I'm cutting 10 boards in a row, I need to move this thing quickly around the edges of the board and move on. The "other one" could zip around quickly, while this one is a big, unwieldy, heavy beast that I'm pinching to hold. 4. The on-off switch doesn't fit easily, even with my large-sized hands. You're supposed to be able to turn it on with your thumb on the left side of the palm rest, and turn it off with your ring finger on the other side. However, in practice, unless you have this sitting on the large, flat work surface when you turn it on, the awkward holding position means my thumb/ring finger don't line up very well, and I often have to hold it up in the air and use my other hand to turn it on or off. If I tried to get my thumb to the power button, it would fall for sure. (See the attached photos) 5. One other small thing (for the design team): when you lay it on its back to change out the sanding pad, it has a tendency to roll over onto its dust-bin side. It'd be nice if you could throw it on its back and have it remain stable while you changed out the pads (which is easier with 2 hands). I've only had this for a day or so, but it's the day after I returned the other one so I have a back-to-back comparison and these items became readily apparent. Some of the things I like about this one: 1. It's a beast. If I drop it, roll it, or use it for self defense I feel it'll still work afterwards. 2. Less apparent feel of vibration on my hand when using it. If it just wasn't so dang bulky. 3. The dust collection works way better than the "other one." I haven't had the common dust bin issues (yet) since I just got it... but compared to the other guy, this actually sucks dust through the holes and deposits it in the bin. That's nice. 4. It works with the Milwaukee tools I now own in the M18 range. 5. The battery (XC 3.0) seems to last a good bit longer than the "other guy." I have a sailboat hull nowhere near a power source that I plan to use this on. I had no fears with the "other one" but with this one I'm really concerned about taking it on. I might have to return this sander and pick up a standalone in another brand to meet my needs. If only I were sanding large, flat items all day. If I were, this would be a no brainer! As of now, I'm still not convinced if I'm going to keep it or not. "The best sander is the one you have on you." I may find myself leaving this one at home...
