Awesome machine. Bought it to start making knives and works perfect. Belts in less course grit probably will have to be ordered online, but that’s not hard to do

This is PERFECT!
i spent a lot of time searching for a quality sander. It seemed that all of the big box brands were made in the same Chinese factory. The circular sander tables were flimsy and wobbled. It looked like the (gag) Harbor Freight unit was identical to the Ryobi, Ridgid (they are the same company).

I saw the Porter Cable and decided it was the one I wanted. It is powerful, well built and sturdy. The only complaint I have is the 8" disc is hard to find locally......

I used it for about 3 hours straight and it did a good job with just a few slow downs. Really nice it has the dust bag. Plan to use hearing protection if by our working for long periods. It's a work house!
