CAUSE

REMEDY

Use the correct blade with a softer bond.

Excessive cutting pressure, or jamming or twisting the blade in the cut can cause the blade core to bend or flex. When subjected to extreme stress and metal fatigue, the blade's steel core will eventually crack.

The saw operator should use steady, even in-feed pressure, and be careful not to twist or jam the blade in the cut.

Overheating through inadequate water supply or improper use of dry cutting blades.

Use adequate water to cool wet cutting diamond blades (for example, 2 to 5 gallons per minute (7-18 liters per minute) for concrete saws). Allow adequate airflow around dry cutting diamond blades to prevent overheating.

RPM is too high.

Check the operating RPM of the blade shaft. Change equipment or blades if necessary.

Blade is out of tension

Replace the blade or have the blade re-tensioned by manufacturer.

CAUSE

REMEDY

Blade is too hard for the material being cut.

Use a blade with a softer bond.
job.

Blade is being flexed in the cut by misaligned saw, or operator making dramatic saw course corrections.

Align saw. If cut has slightly wandered offline, gradually steer the saw back on line. If the cut is way offline, remove the blade from the cut. Align the saw/blade with the cut line, plunge the blade to proper cut depth and resume sawing.

Blade is overheated.

Apply proper cooling.
