First, for those who want to use velcro polishing pads with this unit, it does NOT come with a velcro backing pad. You can buy a PC backing pad (there are two) or you can, like me, for a few dollars more buy a "Meguiars Softbuff Dual Action Velcro Backing Plate For 6 1/2and 7 Inch Pads". It fits perfectly and works well with the supplied balance weight, works well with Meguiar's velcro pads and is reputed to be the best velcro backing pad.

The PC sander/polisher is the first DA unit used by folks for auto work and I think it is still the best. Great performance, great handling, great durability.

Very happy with mine...after the backing pad upgrade.

I ordered this to replace our old Porter-Cable, which worked well for five years. This one lasted four months before the shaft broke - not repairable. We are very disappointed and will order a different brand next time.

After borrowing a 7335 sander for my boat, I liked it so much I decided to purchase this newer 7346SP 6-inch model from Amazon. It is ideal for extensive sanding like I have had to do on a 1961 42 foot wooden Chris Craft boat. Changing paper is simple. Sanding time is way reduced from my previous palm type sander. I would highly recommend this sander to anyone planning extensive sanding or repeated projects requiring sanding. I have not used the polishing pad, but I chose this model which included it because I expect to use it in the future.

I like quality tools and, when I needed an oribital sander/polisher and checked out the models available, I thought this Porter Cable would be a good value. What a disappointment! When running, it has a low-quality feel and sound to it but I could look past that if it worked well. Unfortunately, it doesn't. Based on the positive reviews here, I must have a defective unit. With barely any pressure on it at all, the head stops turning and it slips internally. I'm guessing that the eccentric is mounted without splines or a key to the output shaft or it wasn't tightened properly during assembly but that's just a guess. Of course, you should not bear down with pressure when polishing but this thing starts slipping with just the slightest amount of pressure beyond it's own weight. When running at it's highest speed (or any speed), I can stop the head by simply pressing lightly on the bonnet with just a couple fingers. This would make it absolutely useless for sanding but I wouldn't use this as a sander anyway.

Another thing is that 6" buffing bonnets don't fit this tool even though that's what it's supposed to take at least not the ones I tried. I also tried some 6" lambs wool buffing bonnets that I had on hand and they wouldn't fit either. I purchased this at a HD store and they had no buffing pads to fit this tool.

With tools like this, I like to stick with brand names with a reputation for quality - Milwaukee, etc. But this tool is virtually useless, in my opinion, and I'm returning it tomorrow. I would be better off with a cheap $20 buffer from Harbor Freight! I mean that literally because this tool simply won't work. It's sad that once great American companies are producing lousy tools these days. Not all of their tools are bad but this one sure is.

My first Porter-Cable random orbit sander was used almost continuously for 15 years while building boats in the Caribbean. Barely recognizable after all those years; it remained one of the best tools I ever owned. I eventually purchased another identical unit. The bearings in the head broke down within six months and rendered the unit inop. I purchased a third unit through Amazon. This unit lasted less the 10 hours while sanding a floor. The drive shaft broke separating the sanding head from the motor. It is not repairable. Amazon has replaced it and, so far., I have not taken it out of the box. I don't know what has happened the Porter-Cable brand. They used to an industry standard. My first sander cost approx. $230 back in the mid-nineties. The most recent unit was only $129. I am supposing that this difference also represents the quality difference. It is always a shame to see outstanding equipment made in the USA go overseas (or south....) and turn into crap.

I had to buy this polisher after I nearly destroyed the clear coat on my 2012 Mustang GT at a quarter car wash. I made the big mistake of using the brush on the car body only to find I had scratched up nearly every panel. Took about a week and over $200 in tools and supplies but it looks better now than before the incident. In my rush to replace a Black and Decker 10" polisher that I bought and destroyed in the same day I confused this model with the identical looking PC 7424XP which was the polisher I wanted. I did not realize I had the 7346SP until I went to register the product. Naturally I began to wonder what the difference was between the products and did some research. The 7346SP includes a 6" polishing pad and a 6" sanding pad for adhesive backed sand paper where as the 7424XP includes the 6” polishing pad only. The important difference is the 7346SP ships with the heavy 6" counter weight installed for the larger and heavier 6" polishing pads and 5" sanding disk. The 7424XP ships with the lighter counter weight for 5" and 6” polishing pads. If you are going to use the product with a standard 5" Velcro pad and say a Chemical Guys 6" pad you need the smaller 5" counter weight which can be ordered directly from Porter Cable parts and service in Ontario, CA. It would be much easier to just order the 7424XP but if you find yourself in my position of already owning a 7346SP then you can order the correct counter weight for about $3.00 plus way to much in shipping, $10.00. The service center does recommend getting the correct counterweight to avoid bearing damage and since the swap only involved to screws and five minutes I don't think it is that big of a deal. The up side is you will have the parts for polishing and sanding if needed.Read more ›
