- Tier: Budget tier
- Grit lane: 40, 60, 80, 100, 120
Use it when
The fit is obvious.
- · Reach for the Diablo 5-Inch 80 Discs when the job is rough stock removal, paint stripping, and fast material removal: 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.
Best for
Where it earns its keep.
