What Is a Wet Saw?
A wet saw is an electric cutting tool that uses a continuously water-cooled, diamond-edged blade to make precise cuts in tile, stone, and other masonry materials.
How a Wet Saw Works
A wet saw operates by spinning a circular diamond blade while a constant stream of water flows over it. The water serves three purposes:
- Cools the blade to prevent overheating
- Reduces dust — especially important when cutting ceramic or stone
- Improves cut quality by minimizing chipping
Tiles are either pushed into the blade on a sliding table, or the blade is guided across a stationary tile, depending on the saw design.
Key components:
- Diamond blade — designed to cut hard materials
- Water reservoir or pump — supplies water to the blade
- Sliding table or tray — supports and guides the tile
- Fence or guide — helps ensure straight, accurate cuts
Why Use a Wet Saw?
A wet saw is preferred over dry cutting tools because it produces cleaner cuts, reduces airborne dust, and extends blade life — making it the right tool for any serious tile work.
Common uses:
- Cutting ceramic, porcelain, and stone tile
- Making straight cuts, angle cuts, and small notches
- Trimming tile to fit around edges, corners, and fixtures
