Question: How many PSI does this use? And, can it use polishing discs?
Document: Great little sander. My only gripe is is It did not mention that it only takes adhesive backed sanding discs. I wanted to use abralon pads but i cannot since i now have to find how to replace the pad to get the hook and loop which abralon pads use.
It is hard to say anything but good things for this machine.I have used it many times on my own cars etc and its great.Time will tell.
i am very pleased with my tool i have many IR tools before i became disabled i was a diesl mechanic i rate IR top in air tools i hope they never loose thier qualaty as so many once good brands have i wish they could be made in us only but i know thats probaly asking to much  thank you
!Beware! These grinders are inexpensive and you get what you pay for. Bought 2 and both broke after 10 min of use.
The sander works well but if you are going to use it full time it will require a large compressoer to keep up, my 5hp Ingersol just barely does.
Quality sander. Does the job well! I don't expect any less. Ingersoll rand wins! Make sure you use gloves to protect you hands with the vibration.
We have been using these sanders in our body shop for years and they work fine. They last a long time. I don't personally use them, but the employees have always told me to purchase the same units.
I had a cheaper sander before this one and it only lasted a few hours. This one is so much smoother and quieter. Very nice. BUT it does use one heck of a lot of cfm. But well worth the money.
I bought two of these to replace the POS 2601 Ridgid 5" random orbital sanders. Since 2010 Ridgid Tools are built in a cheaper part of China and their sanders are complete crap. I am lucky to get three months use out of them before the motors burn up.
Its a decent sander for the price. Its not as good as a 4151 as far as ergonomics (the way it feels in your hand).My complaint....there is no way (or tool supplied) to lock the spindle to remove the pad. I was forced to use a pair of channel locks.The sad fact, all air tools are made in China anymore and quality is not as good as it could be.
Answer: no
