  • Format: Discs
  • Tier: Pro tier
  • Grit lane: 60, 80, 100, 120

Use it when

The fit is obvious.

  • · Reach for the Festool Granat 5" 100 Grit when the job is intermediate wood prep, Festool orbital sanders, and hardwood transition pass: 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 the working middle: enough bite to matter, refined enough to leave the job somewhere worth continuing.

Skip it when

The job asks for something else.

  • · Leave it if you are actually solving a different stage of the climb than the one this pick was chosen for.
  • · 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.

  • · intermediate wood prep
  • · Festool orbital sanders
  • · hardwood transition pass
