Wet or dry cutting: Which is right when?

Wet cutting: cool, clean and long-lasting

When cutting wet, water cools the diamond segments and traps dust right at the cutting point. The blade stays sharp longer, the cut is cleaner and you work without a cloud of dust.

Wet cutting is especially worthwhile:

• for hard and abrasive materials such as granite, porcelain stoneware and reinforced concrete
• for long, deep cuts with a floor saw, table saw or wall saw
• indoors, where dust must not be produced

Dry cutting: flexible and fast

Without water, you have more freedom to move: no hose, no slurry, no water damage. But the blade gets hotter. Work in intervals and let the blade run freely for a short time between cuts so it can cool down.

Dry cutting is particularly suitable:

• for short cuts and adjustments on site
• with an angle grinder
• when water cannot be used, for example near electrical installations

Protect yourself from dust

Cutting concrete, natural stone and ceramics produces fine silica dust. If you cut dry, use dust extraction and a suitable respirator. Wet cutting significantly reduces dust.

Which blade for which method?

Check the marking on the blade: many diamond cutting blades are approved for both wet and dry cutting, while some are approved for wet cutting only.

Segmented blades with cooling slots and turbo blades handle dry cutting well. Continuous-rim blades for tiles and porcelain stoneware work best wet and produce the cleanest edges.
