Product Description

Amazon.com Product Description

The DELTA 31-120 12-Inch 1/2 HP Benchtop Disc Sander is designed with a smooth-but-powerful 1/2 HP, 120-volt motor spins the sanding disc up to 2,500 RPM to suit the needs of the professional craftsman. The heavy-duty disc sander includes a steel disc plate that holds a 12-inch diameter, 80-grit abrasive disc. The sander's cast-iron base construction reduces vibration and includes base holes for bench mounting. The cast-iron table comes with table-locking handles and tilts to positive 45 and 90 degrees, while a 3/8-inch-by-3/4-inch miter gauge slot is built into the table for angled and straight edge sanding jobs. A top manual brake puts a stop to sanding in mere seconds. The integral dust collection fan carries debris away from the table, and the built-in dust hose with 2-1/4-inch OD connectors attaches to most standard shop vacuums.

4.0 out of 5 stars Great tool, not outstanding, January 3, 2004

This review is from: DELTA 31-120 12-Inch 1/2-Horsepower Benchtop Disc Sander, 120-Volt 1-Phase (Tools & Home Improvement)

This is basically a good sander but there are some issues that I discovered. The wheel has axial runout of 0.020 inch at the rim which surprised me, I expected something more like 0.002 inch. Changing the sanding disks is time-consuming. The stock disk is 60 grit, too coarse for my work. It took me an hour to change it. This is because the stock disk leaves all its glue residue on the platter, which is very hard to clean off. I used acetone and steel wool. The platter is smaller than standard so I had to trim the new disk so it would work at all. The angle gauge is very cheesy, it is fixed at 2 points and bows off its mounting surface in between. Despite these problems, I was able to get my job done nicely with this tool. It runs real quiet, is very powerful, and basically user-friendly. The precision table and large size are nice. The 45 degree position stop is not very "crisp" but may improve with use. The tool is greatly enhanced with the Delta 34-779 mitre gauge, available separately. No mitre gauge was included. All in all, it's a good tool but obviously a tool made in China to meet a price target.

This review is from: DELTA 31-120 12-Inch 1/2-Horsepower Benchtop Disc Sander, 120-Volt 1-Phase (Tools & Home Improvement)

I am pleased with this sander. While I would like it to be a bit more powerful (will do whatever I want as long as I take my time and don't push it) it gets the job done for a very low price.

Also, the "positive" stops at 90 and 45 degrees could be better designed and more accurate, but again, if I take my time and set it up carefully each time they work well.

The castings are not perfect, but the table is very flat and I have little runnout...so the casting defects are cosmetic. Again, for the price a nice machine.

This review is from: DELTA 31-120 12-Inch 1/2-Horsepower Benchtop Disc Sander, 120-Volt 1-Phase (Tools & Home Improvement)

Not happy with this purchase at all. Seems to be a lot of variance in the units. I looked at a unit built some years ago, and had a chance to work with it, and it was a dream. Smooth, quiet operation, solid construction, precise, clean fit among parts.

When I received mine, the fan cover had slipped, shearing off the screws that hold it in place. Amazon was excellent in getting a new one to me.

The new one works as well as can be expected, but is extremely disappointing. The assembly and stop set to keep things in square is cheap and has excessive play. The milling on the mini table was miserable -- obvious quality control problems. I had to machine the table down myself. (I chose to do this rather than getting another unit shipped out.)

I finally have a machine that works fairly well, but I had to put in a lot of effort and time to get it to that point. I would suggest carefully examining all other options before purchasing this Delta Disc Sander.

Happy shop time....
