Overall this is a really nice sander that takes very little space on the workbench. Does a great job, heavy with lots of get up and go, a very nice product. This tool is quiet, and devoured every thing I threw at it. This sander has more than enough power for any material from soft wood to hard steel. This is my first Delta product and for sure I'll be buying more.

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.

It's true that the Delta 31-140 was the 12 Inch Disc Sanders that we ranked most highly. However, there were a handful of other really premium quality 12 Inch Disc Sanders we wanted to showcase here that just barely missed first place.

Next on our list is built by Powermatic which is a very highly regarded tool brand. Powermatic's Disc & Belt Sanders are one of their top products. It was terrific to check out the 1791291K. I was very pleased using this tool!

The Powermatic 1791291K Disc & Belt Sander, at $1599.91 is an especially excellent Sander for the money. The Powermatic 1791291K is really a solid alternative. Of you are unsure about our top pick, I'd suggest you select this Sander.
