💡 How do you optimize air pressure for a pneumatic die grinder?
Setup matters more than raw power for consistent results.
- Maintaining 90 to 120 PSI provides steady rotational torque for heavy grinding tasks
- Using a clean dry air feed prevents internal moisture buildup and extends lifespan
- Attaching a quick connect fitting makes swapping outlets a totally handy workflow upgrade
