Use it when
The fit is obvious.
- · Reach for the Norton ProSand Drywall 80 when the job is rough drywall pass, mud leveling, and high spot removal: that is the fight it was built for.
- · Aluminum oxide is the reliable one: cheap, tough, no surprises and no complaints. It will outlast your patience before it outlasts the job.
- · 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 on the shelf if you are flattening big panels all day: a random orbital keeps pressure even where your hand drifts.
Best for
Where it earns its keep.
