Tips for Getting the Best Results with Your Double Turbo Grinding Cup

Here are some expert tips to extend the life of your ROC Abrasives cup wheel and get smoother finishes:

✅ Use the right speed: High speed isn’t always better; check your grinder’s RPM range to match the wheel’s specifications.
✅ Don’t force it: Let the diamond segments do the cutting; excessive pressure creates heat and shortens lifespan.
✅ Wet vs. dry grinding: Wet grinding can reduce dust and keep the wheel cool but isn’t always possible on site.
✅ Keep it moving: Avoid staying in one spot too long to prevent gouging or uneven grinding.
✅ Clean the wheel: Periodically run it over a dressing stone to expose fresh diamonds if you notice glazing.

Following these tips ensures the cup wheel stays effective job after job.
