I thoroughly enjoy using my 12” disc sander, and am considering the purchase of a second one so that I can move to a second grit without all the hassle of changing papers. My current disc sander usually has an 80 grit disc on it. So my question is this:. If you had an 80 grit disc on your sander, and bought a second one, what grit disc would you likely keep on the second one? Thanks.

I can’t see much use in going finer than 120. It’ll just clog and burn up in short order. I’d go to 120 as well. 220 maybe if it was a variable speed motor I could slow down.

I don’t know how the disc platen attaches to your machine but would it be possible to buy a second platen and keep a different grade paper on there and just swap the platen out? Might be just as much hassle as swapping paper but thought I’d throw it out there…

Do you have a lathe? You could make as many platens as you like (can afford) and mount whatever grit you want. If you thread the spindle mount rather than chuck, changeout takes seconds with minimal/negligible runout.

While dust collection is another issue, but it wouldn’t be your workhorse.

Have you ever used other grits on your present sander, which do you like besides the 80g?
If you haven’t tried any others, then experiment and use what works best for you.

100g is probably as high as I would go.

Thanks for your recommendations, guys. Much appreciated.

Ducky, after nearly 50 years in the shop I have no lathe. No room, unfortunately, but thanks for the suggestion.

LeeRoy, the only other grit used was 100, and I didn’t notice much difference between the two. Have been considering 100 and 150, both in alumina-zirconia. I’ll report back if I have success with that arrangement.

Have your say...
