💡 What is a handy question about flap discs and how to choose grit for a project?

A practical guide to grit selection helps you get the finish you want with fewer passes.

- For fast material removal on metal, start with 40 or 60 grit and finish with 80-120 for a smooth surface. - On wood, use 60-80 grit for shaping, then 120 for a clean finish. - Always use proper PPE and follow RPM guidelines for safe grinding.
