Use it when
The fit is obvious.
- · Reach for the Diamond Needle File Set when the job is deburring metal, stone shaping, and glass work: that is the fight it was built for.
- · Diamond is the only grain hard enough to boss stone, glass, and cured concrete around. Everything else just negotiates.
- · 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 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.
