Dewalt Diamond 9" Wet/Dry Disc

Dry Cutting: Offers speed and convenience, typically done with segmented or turbo rims. However, it generates more dust and heat, which shortens blade life. Wet Cutting: Requires a water feed (like the DEWALT Portable Water Tank system) to cool the blade and suppress dust. This extends the blade's life significantly and is required for fine materials like ceramic and porcelain tile to prevent chipping and cracking.
