The second problem is the belt tracking adjustment. The disc sander housing was very rough and chipped. I think this is a great grinder for the new knife maker. First I think the factory provision for dust collection is poor. Machine speed is 1725 RPM and this works very well.

The Delta 31-140 was definitely our favorite 12 Inch Disc Sanders. That being said, there are a few other fantastic alternatives when it comes down to 12 Inch Disc Sanders. We have a breakdown of them here.

Powermatic is another leading maker of Sanders. They build the tool that is next on our rundown. Powermatic's Disc & Belt Sanders are one of their top products. It was fantastic to test the 1791291K. I was very satisfied using this tool!

The Powermatic 1791291K Disc & Belt Sander, at $1599.91 is an especially excellent Sander for the price. If you unsure about our number one pick, I'd check out the Powermatic 1791291K next. It's a first class tool at a terrific price.
