Use Dry Or Wet Diamond Blade While Cutting
May 26, 2014
Diamond blades work best when cutting wet. The water will prevent the diamond blade from overheating and distorting in shape, it reduce harmful dust created by cutting, and will remove the slurry from the cut. Diamond cannot withstand the forces involved at the elevated temperatures of dry cutting ceramic and abrasive materials, and will be subject to rapid tool wear and possible failure. Blade life is greatly extended by wet cutting. However, many saw blades are designed to operate either wet or dry.

Dry diamond blade should be limited to situations where water isn't available easily or used in electrical saws machine.

When doing dry cutting, the diamond blade should be allowed to cool off periodically. Cooling can be increased by allowing the blade to spin freely out of the cut. Cut this way for a few minutes, then you should start to see the cutting surface get some shape back, this causes the bond to wear away and expose the diamonds which do all the cutting. This allows cool air to pass between the segments.

Dry diamond blade cutting is dangerous for persons unfamiliar with the risks and process.

After choose the right diamond blade, how to let diamond blade to cut faster? If the blade starts to cut slower than normal, the best way to adjust this problem is to find a hard surface like cured concrete and drop the level of water you are pumping over the blade.

Cut this way for a few minutes, then you should start to see the cutting surface get some shape back, this causes the bond to wear away and expose the diamonds which do all the cutting.


Sometimes, people found their diamond blade is easy to distort. Many people apply more pressure to the saw to force the blade harder into the material when it’s not cutting as fast as they would like, but this can cause the blade to overheat and distort in shape, throw a segment, this is unsafe for the operator and bad news for the diamond blade.

Generally speaking, it is better to cut with water if the condition allows.
