Symptom:Eccentricity Cause:The diamond saw blade shaft may have a groove scored in it, caused by a diamond blade spinning between the flanges. A new diamond blade, installed on the arbor shaft, will seat into the groove, and immediately run eccentrically when the saw starts. Remedy:Replace worn shaft. Diamond saw blade

Sympton:Eccentricity Cause:The bond is too hard for the material being cut. The hard bond retains the diamonds, and they begin to round off, causing the diamond blade to become dull. Instead of cutting, the diamond blade begins to “pound,” causing the blade to wear out-of-round. Remedy:Change to a softer bond, which will wear away more readily allowing the dull diamonds to be released and sharp, new cutting edges to become exposed.  granite cutting blade
