Use it when
The fit is obvious.
- · Reach for the Diablo 6-Inch 80 Discs when the job is rough stock removal, large panel prep, and 6-inch sanders: that is the fight it was built for.
- · Ceramic grain fractures into fresh edges as it wears, so it stays hungry long after cheaper grit goes dull and starts rubbing instead of cutting.
- · This is a cutting grit, not a finishing one. It removes material and the surface’s attitude: it does not make anything pretty.
Skip it when
The job asks for something else.
- · Leave it if the surface is already close to finish-ready. This grit will chew through good work just to prove a point.
- · Leave it if longevity and cut speed matter more than the price: cheap abrasive is cheap for reasons you feel on the tenth sheet.
- · Leave it if the work is edges, profiles, and tiny repairs: those are easier to control by hand.

Ceramic grain on a 6-inch platform. Aggressive enough to open up rough stock, built for the machine that runs all day without complaints. In short: it earns its keep on rough stock removal, large panel prep, and 6-inch sanders.
Is 80 the right grit lane for this?
It sits closest to 40 grit, 60 grit, 80 grit, 100 grit, and 120 grit. This is a cutting stage, not a finish stage. Use it to remove material, not to fake smoothness.
What should you put it up against before buying?
Put it against other discs in the same price band doing the same job: that is where speed, finish, and cost-per-use sort themselves out.
