Use it when
The fit is obvious.
- · Reach for the Norton Flap Disc 4.5" 60 Grit when the job is weld prep, metal transition sanding, and angle grinder finishing: that is the fight it was built for.
- · Zirconia runs hot and tough. It is the grain that grinds metal into an apology and asks for the next weld.
- · 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 you already know you want the premium option; a mid-tier pick is a compromise, and you clearly are not in the mood for one.
- · Leave it if the work is edges, profiles, and tiny repairs: those are easier to control by hand.
Best for
Where it earns its keep.
