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 fact is that the Delta 31-140 was the 12 Inch Disc Sanders that we rated the highest. That being said, there were a range of other truly premium 12 Inch Disc Sanders we wanted to showcase here that barely fell short.

Powermatic is an additional major manufacturer of Sanders. They make the tool next on our list. Powermatic's Disc & Belt Sanders are no exception. I was ready to try the model 1791291K and I was not disappointed!

This Disc & Belt Sander is merely $1599.91. That is a terrific deal for a top quality Sander like the 1791291K by Powermatic. The Powermatic 1791291K is really a solid alternative. Of you are unsure about our number one selection, I would select this Sander.
