General purpose 9" disc grit? - ®smpr_fi_mac® - 02-01-2018
Yeah, I'm a noob. I have a belt/disc sander and have *never* used the disc. What grit should I purchase? I don't imagine I'll switch it out to change grits much, will I?

What are you going to sand or grind with it? That will make a big difference. I have 80 grit on my 12" disk to sand segmented rings flat.

I kept an 80 on mine when I had one. Sold it several years ago (combo) when I purchased my 6x89

I have 120 mounted on mine.

It'll be used for sanding rounds on wood and plywood. I'm thinking 80 grit will serve me well, but just wanted some input from others.
I currently use 80 grit on the belt part of the sander for sanding down miter splines and shaping.

80 grit is pretty aggressive, I have it on my 12", next time, 100.

I use 80grit. Its not a final sanding or finish prep sanding device for me. Mostly shaping or removing unwanted material from parts. I use mine on wood, plastic, and metal. Mine is also variable speed which helps.
