Timothy J Silverman used the burrs from a peppermill to convert his drill into a handy coffee grinder. Use this along with the drill scrambler and you’ve got yourself a real workshop power breakfast!

Update: The maker adds –

I don’t recommend using peppermill innards to grind coffee. They grind better than a commercial propeller-style grinder. But they’re just too small to get the job done in a reasonable amount of time.

The next iteration will use real coffee burrs from a real coffee grinder. I found some to salvage, but they’re also available as replacement parts. Then I can use a hand crank instead of the drill. That should make those who share my office, where this device is normally used, happier.

    That’s me! I should point out that I don’t recommend using peppermill innards to grind coffee. They grind better than a commercial propeller-style grinder. But they’re just too small to get the job done in a reasonable amount of time.
