Customer Reviews

5 in. Random Orbital Sander is rated 4.3 out of 5 by 157.
Rated 5 out of 5 by from Excellent Product I'm at a point where I'm tired of going cheap on tools and products. I've decided to spend the money necessary in order to get the quality items I need in order to complete a task. This sander is a perfect example of that. It's not much more than the cheapy ones, but you get a lot more bang for the buck. It's got plenty of power, good on/off switch, adjustable speed, and a long cord . . . and a 5 year warranty. This thing removes wood! The solid case is of lifetime quality and leaves plenty of room for the sander as well as many extra sanding pads. I'm very happy with this sander. Hopefully the kids' bunk beds will be done soon!

Rated 2 out of 5 by from Good tool but trouble I was only able to complete one job with this sander before the hook n loop pad stopped holding the sandpaper. Now I have to buy a replacement pad. Not good when you consider Milwaukee' s "tool - reputation". I'll definitely buy a new sander, (not Milwaukee), from someone else.

Rated 5 out of 5 by from Fantastic Sander! I am an accomplished woodworker (everything from simple projects to high-end furniture and cabinetry, and I have five of the top brand sanders. I needed to replace one that broke down unexpectedly and purchased this Milwaukee orbital sander from Home Depot. I had previously seen that it had won tool reviews as a top sander, but was skeptical of the performance reviews for such an inexpensive tool. After trying it out, I was amazed! It works every bit as good as the reviews. The best two features: 1.) It removes material faster than any sander I own (including a heavy-duty 6 inch angled Dewalt sander), and 2.) It has a modified brake that winds down very fast after turning it off---a great time saver. Don't be afraid of the fast material removal - it also leaves the smoothest finish of all my sanders. I will purchase at least one more, so that I can do several levels of sanding without changing paper (or using some of my other lesser performing sanders). You cannot buy a sander close to this quality unless you spend $120 (or more) and buy the Porter Cable 390 low profile orbital sander.

Rated 5 out of 5 by from Monster sander power This is actually the second time I've purchased this sander model. I bought it because I have a woodworking buddy and we both needed/wanted one. This sander is powerful and best of all the dust collector works. I even sand inside my shop now without getting sawdust every where. It's quiet and smooth running. Love it and do not hesitate to brag about it.

Rated 5 out of 5 by from Wish I bought this years ago, quick change and variable speed I needed to sand all my kitchen cabinets and this sander is a god send. It is so easy to change discs and the variable speed is great for final sanding. Add everything together with Milwaukee tool durability and you get one great tool.

Rated 5 out of 5 by from Yes, you can use this on floors. It's a long story but I'm using this to sand parquet floors in two bedrooms. This little sander is a beast and has no trouble being slightly misused in this way. Buy this for anything you'd ever want to sand. I like this so much, I actually wrote a review-I've never ever review anything online in my life.

Rated 5 out of 5 by from Great product! Best I've seen. Sands great. No swirl marks. Speed settings are easy to use. Feels great in your hand and comfortably easy to control.

Rated 3 out of 5 by from decent sander I use this as a start to finish sander on may projects from chests to small items. I like the speed control and the large exhaust port. It seems to pick up a lot dust under its own power. The dust bag fills up quick. Not so great. Well it needs to be in constant contact with work surface even a little lift will cause the base to speed up to a unstable Rpm. and you need to shut off the unit let it stop spinning and put it on the material again start it up. considering the switch is not easy to always turn on or off. I do not know whose vacuum hoses they tried these on but they are the same size as my vacuum hoses either 2.25 or 1.25 same Diameter. I have not be able to find an adapter that does not take the size I need to hook this up to a dust collector without a 4 inch outport.
