Can I dry drill or use water, whats the best option?

Hi there, Thank you for your question! Yes, this Spyder diamond hole saw can be used either dry or with water. However, using water is the best option whenever possible. Wet drilling helps improve performance by reducing heat buildup, minimizing dust and debris, and extending the life of the diamond abrasive. Dry drilling can still be used for convenience, but it may result in faster wear compared to wet use.
