I treated myself to a drill bit that fits on top on Porlex/Hario grinders over xmas. Much better for grinding coffee for French press or cold brew. Also the look on peoples' faces when I use a drill to make coffee makes it worthwhile.
Ha! Done that, makes it super easy eh?
My.buddy melted his grinder doing this though, too much coffee to fast, oh and beware the hammer setting!
Have made sure not to go too fast with it! I'm sure hand grinders weren't designed to handle 1,300rpm! Tend to keep it at something more like 1.3...
