I decided to take a chance on this sander. Got it yesterday, slapped a new 120 grit sanding pad on it and gave it a try on some hard maple. Not sure if I’m doing something wrong or I got a dud but the thing only seems to work on a flat surface. I tried using it on the edge of the 3/4” piece and it wouldn’t event rotate. Even on the flat surface it seems to rotate slowly (and I have the speed control maxed).

I have an older Porter Cable sander and it goes fine on the edge and definitely faster than this newer one.

Has anyone else had this experience?

Is this a random orbital sander or a pad sander?

HMMMMM? New and improved! BUT WAIT, we’ll send you a second sander. Just pay additional shipping and handling.
Now I feel better.

I think you got a dud. I have the DeWalt identical twin to your Porter Cable and don’t have the issues you have.

^I think you got a dud too. One of these powertool guys might have an idea for swapping brushes, bearings, whatever those little guys have. For what it’s worth, I have cheap sanders and expensive sanders. I’ve had good luck with DeWalt on the lower end of price.

I think the problem is how you are gripping it…I’ve owned several PC ROS machines and found that they don’t spin with even minimal downward pressure. I don’t have the low profile model but on the normal ones I grip it below the top (like holding a beer can) solely to guide it…let the machine do the work.

Give it try. If I’m correct, I’ll say you’ll be happy with it.

Likely a dud. I have this sander and it works well. A thought though: I would avoid using a ROS on edge grain. Too risky to round over where you dont want a round over. This is where a palm sander comes in handy.

Are you talking about the RO palm sander? I recently picked one up (after rebate, $35). I noticed that very same phenomenon. I fired up my older B&D Quantum and it works as expected.

I guess we both have duds?

“I think the problem is how you are gripping it”

I have a regular Porter Cable ROS (regular profile) and you have to press down pretty firmly to make it stop. On this new one with a speed control, anything less than full speed results in no turning of the pad under its own weight.

Guess I’ll send it back. Not sure if I want to risk another one or just stick with my old one. I liked the idea of the low profile for tight spaces.

rut…if that’s the case, probably a dud although I would try one more thing…lift it and turn it on to see if it spins.

PC was ruined IMHO when they were bought by BD/Dewalt. My guess is that PC quality tools were killed so they could shift the brand to “yellow”.

It does spin when lifted but nowhere near 12000 rpms (the reported top speed).

I love my Milwaukee ROS. Got it when I returned the PC I bought previously. And it really works great hooked up to my shop vac for an almost dustless experience. I use a light touch with the ROS as it is too easy to “lean it over on edge” a bit if you press down, causing swirls ….. or as I call them, “more sanding”!

model number 390 or 394 rut? (just so I know to avoid it!) I run the cheap “single speed” palm model PC’s here and love them. the only variable speed model I own is that thing that looks like a car buffer and I only use it because it is PSA paper and makes quick work when needed.

^I didn’t even know Milwaukee made a ROS! Shows how much I know. I’m going to check them out. Thanks!

jaidee I was a Milwaukee fan for years but then that German company came in and ruined that brand in favor of their own (seems to be a pattern on power tools huh?). I understand Milwaukee is now back with quality tools but many people “burned” during their bad time will still be leery of buying them again. And when you say “swirls” with a ROS…hmmm…that is the purpose of ROS and you shouldn’t have any if you step-up the grit on the sanding medium (rough stuff I might start with 50, then go to 120 and finish with 220).
