Use it when
The fit is obvious.
- · Reach for the 3M Featheredge 220 Grit when the job is featheredging paint, spot putty sanding, and auto body prep: that is the fight it was built for.
- · Silicon carbide bites sharp and fast, and it loves water. Brittle, brilliant, a little reckless: the grain that leaves glass when you keep it wet.
- · 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 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 on the shelf if you are flattening big panels all day: a random orbital keeps pressure even where your hand drifts.
