The verdict

Where this pick fits.

The extra-fine pass most abrasives skip past. Granat 400 holds its grain through multiple coats of lacquer where standard aluminum oxide would have quit two passes ago.

Extra fine. Holds its edge past where everything else gave up.

Use it when

The fit is obvious.

· Reach for the Festool Granat 5" 400 Grit when the job is fine lacquer work, between multiple coats, and Festool 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 refinement territory. It flatters a surface that is already close; it will not rescue a rough one.

Skip it when

The job asks for something else.

· Leave it if you still need to remove stock, paint, filler, or machine marks; fine grit only polishes over problems it cannot fix.
· Leave it if the budget is tight enough that value-per-pack matters more than top-end feel and longevity: good mid-tier paper will get you there slower.
· 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.

· fine lacquer work
· between multiple coats
· Festool sanders
