Greg Scholl explains how straight grinders, angle grinders, and microgrinders prove their usefulness in his shop. He talks about why pneumatic grinders have an advantage over electric ones, and how their main disadvantage is that they require frequent oiling. He uses them to shape wood without clogging or catching. Scholl uses them for sanding, removing rust from old tools, and cutting and grinding metal – handy when restoring old furniture that has hidden, embedded nails. He also shares important safety tips.
