Quick Tips
- If you grind hard material choose a softer grade.
- If you grind soft material choose a harder grade.
- If you are unsure about optimal hardness, start with a softer quality and move step by step towards harder qualities.
- If quality appears soft, increase RPM.
- If quality appears hard, decrease RPM.
